Requirements and Prompts

Submit 15 images that demonstrate:

  • Sustained Investigation through practice, experimentation, and revision (P,E,R)
  • Sustained Investigation of materials, processes, and ideas
  • Synthesis of materials, processes, and ideas
  • 2D/3D/Drawing skills (depending on the type of portfolio submitted)

State the following in writing:

  • Identify the Inquiry or Question(s) that guided your Sustained Investigation
  • Describe how your Sustained Investigation shows evidence of practice, experimentation, and revision GUIDED BY your Inquiry or Question(s). (1200 characters maximum, including spaces, for a response to both prompts)

Questions that guide the Sustained Investigation are typically **formulated at the beginning of portfolio development.**Students should formulate their Inquiry or Question(s) based on their own experiences and ideas. These guiding questions should be documented and further developed throughout the Sustained Investigation.

The Rubric

Scoring Criteria - Let's break it down! 🤔

Row A

Row A deals with your Inquiry, "the process of asking questions in order to seek, to search, and to discover". As you can see, this score point assesses whether or not you IDENTIFY an inquiry and if your work is a visual answer to the inquiry.

For instance, if the inquiry identified is "How can I use the translucent properties of oil paint to represent the beautiful variety of skin tones through underlying colors in portraits of POC?", possible points could be broken down like this:

1 pt: You state your inquiry (Guiding Question) and your visual evidence was unrelated paintings in various media. There might be a portrait in there, there might be an oil, there might be a POC, however, they aren't ALL aligned with your inquiry. You didn't support or demonstrate the inquiry statement with the visual evidence. Alternatively, you don't give an actual INQUIRY, but possibly just wrote something like "I wanted to get better in my art".

2 pts: You IDENTIFY the inquiry and may show art that doesn't necessarily showcase portraits of POC, maybe it's all portraits - but not all POC or all done in oil. It relates but doesn't ANSWER your question. The visual evidence demonstrates awareness and an attempt at showing the inquiry but is not entirely successful.

3 pts: You IDENTIFY the inquiry, and it is clearly evident that the question GUIDED all of the work. Your visual evidence SUPPORTS the idea of the inquiry - there are all oil paintings of POC. but there might be uneven success - this means some of the work might be of a better/lesser caliber than others.

Row A counts for 12% of your overall score and is represented by "SI-A" in the self-grading formula above.

Row B

Row B deals with Practice, Experimentation, and Revision (P,E,R)

  • Practice—the repeated use of materials, processes, and/or ideas
  • Experimentation—TESTING materials, processes, and/or ideas
  • Revision—making a purposeful change, connection, or improvement

Breaking down the score points, please notice Row B seems to dovetail nicely with Row A. If you don't have a sustained investigation (guided by inquiry), you can't practice, experiment, or revise it. Make sense? 😉 😎 For the example above, the things you might address for this row would be things like mixing shades, practicing applying paint in a glazingtechnique (building up thin layers of paint to create depth), trying underpainting, posed vs. candid portraits, different compositions and backgrounds, etc.

1 pt: You DO SHOW any or all of the P, E, R, but your work does not show a sustained investigation. Using the example inquiry given for row A, you might have tried a variety of techniques but say you did a variety of paintings - maybe portraits, landscapes or still life, and they might not be in oil.... so it doesn't tie to your Sustained Investigation.

2 pts: Your P, E, or R relates to the SI (notice that you have an SI here, which differs from point 1) AND your written evidence RELATES to your visual evidence. So you have the SI, and it is tied to your visual evidence, similar to the Row A score point 2. So you have an idea, you tried some stuff, but it's still not solid. Example - You try creating different skin tones, but they aren't for POC, it relates.... but it's not the evidence you need for what you wrote.

3 pts: Your P, E, or R is not only obvious but what you learned from it DRIVES the work and you are able to articulate it in the written evidence. Your P.E.R all aligns with and revolves around the different ways you used of oil paint to create varied portraits of POC.

Row B counts for 18% of your overall score and is represented by "SI-B" in the self-grading formula above.

Row C

Row C deals with the Materials, Processes, and Ideas (M, P, I).

  • Materials—Physical substances used to make works of art and design
  • Processes—Physical AND conceptual (thought, planning, organizing, etc) activities involved with making works of art and design
  • Ideas—Concepts used to make works of art and design (that can be evident virtually or in writing)

For this score point, you need to show how you conceptualized the work, what you used to help plan or visualize it, and the physical media you chose to create it.

1 pt: Little to NO evidence that M, P, and I work together. So, if you just "paint stuff" - that is the use of a material(M). Simplistic, right? 🤔 It doesn't show that you planned or picked (P) painting for any reason other than you just wanted to paint (no idea). There's nothing tying everything together except a media.

2 pts: Visual relationships between M, P, and I become evident. Here, let's say you created those same paintings (M) of different things but added sketchbook evidence showing you tried different things as well. That becomes a process (P). You are showing the relationship of M and P visually.

3 pts: The evidence supports that ALL THREE (M, P, and I) components are working together as a result of your choices. This is SYNTHESIS. So, for this.... you created paintings (M), you used your sketchbook (P), and then decided to make them all portraits (Idea - following your SI guided question)

Row C counts for 18% of your total score and is represented by "SI-C" in the self-grading formula above.

Row D

Row D deals with your skills. You may review those skills here 2D/Draw or 3D. Please note that this is the only portion of this rubric that really addresses how well you actually DO the art. The majority of this rubric is about how well you THINK, EXPLORE, EXPERIMENT, and REVISE your guiding question. It cannot be understated how important it is that the guiding question comes first, as all SI work should spring from it! 🙌🏽

1 pt: Rudimentary (emerging or underdeveloped) skills. Be honest with yourself. If you need to improve, get to work. You can do it! 👍🏽

2 pts: Moderate (adequate) and good (proficient) skills. Lots of work falls here. Remember, it's a range in each band and this one tends to be big.

3 pts: Good (proficient) and advanced (highly developed) skills. Like other bands, place yourself where the majority of the work scores!

Row D counts for 12% of your total score. SI - D for the above formula.

Hopefully, this will help you score your work as you go, identify your strengths and weaknesses, using the rubric, to create the best portfolio possible. 🙌🏽 🥰 🎨

Sustained Investigation Examples🥳

Here are some examples provided by the College Board. Practice using the rubric to evaluate them, since you will know the score - it's a great way to see if you grasp the rubric and to figure out what parts confuse you. At the end of each example, the give a rationale about why that work received the score.

As you practice with these examples, it's important for you to remember several things.

  • These are designed to demonstrate score points and there is a broad range of achievement within each band.
  • They are not listed so you can copy the work. This work is already created. You need to create the work only YOU CAN CREATE. 🥰. Show the what is important to YOU.
  • Do NOT compare yourself to these works. Artists come in all different skill levels, work across many media, and deal with different ideas. Don't feel that your work is less than any work shown..... it's just different. Different is good! 🙌🏽 💯

Frequently Asked Questions

What exactly does "synthesis" mean in the AP art rubric and how do I show it in my work?

“Synthesis” on the Selected Works rubric means the materials, the making processes, and the ideas are integrated—so they work together visually and conceptually across your five pieces. For a top score (5) you need strong, observable relationships among all three: the materials you choose should reinforce the idea, the processes should shape how that idea appears, and the finished visuals should make that connection obvious. Show it by repeating and developing a material/process combination that expresses your concept consistently (but not identically) across all five works, using advanced 2-D/3-D/drawing skills to make the relationships legible. Remember: your short written IDs must match what’s visible—if writing is unrelated, the portfolio can’t score above a 2. For examples and rubric language, see the Topic 4.2 guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX). For more practice applying the rubric to samples, check Fiveable’s Unit 4 resources (https://library.fiveable.me/ap-studio-art/unit-4) and practice problems (https://library.fiveable.me/practice/ap-studio-art).

How do I write artist statements that actually connect to my artwork for the selected works section?

Write statements that literally point to what the image shows and how you made it. For each Selected Work (100-character limits), name: 1) idea(s) visually evident, 2) materials, 3) processes, 4) digital tools/image citation. Use concrete verbs for processes (painted, printed, welded, stitched, layered), specific materials (acrylic on canvas, found wood, graphite), and a short idea phrase that matches visible content (e.g., “urban erosion / layered maps”). Tie the wording to elements/principles you used (line, texture, figure/ground, scale) so readers see synthesis of materials, processes, and ideas. Avoid vague language—if the writing is unrelated, max score is 2. Aim for consistency across your five works so the written idea is visually evident in each piece. For examples and practice prompts, check the Topic 4.2 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and try practice problems (https://library.fiveable.me/practice/ap-studio-art).

I'm confused about the difference between materials, processes, and ideas - can someone explain with examples?

Materials = the physical substances you use (oil paint, charcoal, clay, found wood, digital pixels). Processes = the physical and conceptual activities you do with those materials (glazing, collage, carving, welding, printmaking, digital layering, cross-hatching). Ideas = the concepts or themes guiding the work (identity, memory, environment, systems, narrative). Examples: - Painting: Materials = oil on linen. Processes = underpainting, glazing, impasto. Idea = fragmented memory. The visual shows thin underpainting + thick impasto to mirror how memory adds/erases detail. - Sculpture: Materials = salvaged wood and metal. Processes = cutting, welding, assembly. Idea = consumer waste → reuse. The joins and patina make the concept visible. - Drawing: Materials = charcoal on paper. Processes = smudging, erasing, cross-hatching. Idea = light vs. shadow in urban spaces. For Selected Works you must identify each (100 characters each) and show visual relationships—judges look for synthesis across materials, processes, and ideas (strong synthesis = score 5). Need practice? See the topic study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and 1,000+ practice problems (https://library.fiveable.me/practice/ap-studio-art).

What's the difference between "good" and "advanced" 2-D skills according to the AP rubric?

“Good” (proficient) vs. “advanced” (highly developed) 2-D skills on the Selected Works rubric is basically about degree and consistency of craft, composition, and use of 2-D elements/principles across your five works. Good/proficient means your works show clear control of line, value, color, space, figure/ground, composition, balance, contrast, etc., and choices support the ideas—competent, deliberate, and effective. Advanced/highly developed means those same skills are pushed further: more sophisticated composition, nuanced handling of color/value/texture, complex relationships (layers, transparency, hierarchy), and skill that consistently elevates and deepens the concept across works. The rubric expects “advanced” to be evident across the portfolio and to contribute to synthesis with materials/processes/ideas (Score 5), while “good” can earn Score 4 when synthesis and written evidence are solid. For examples and tips, see the topic study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and practice problems (https://library.fiveable.me/practice/ap-studio-art).

How do I know if my written evidence is strong enough or if it's "completely unrelated" to my work?

You’ll know your written evidence is strong when it directly matches what the images show—not just thematically but through observable materials, processes, and ideas. The CED says written evidence should identify materials, processes, and ideas; if it’s completely unrelated, the portfolio can’t score above a 2. So: - Be specific and observable: name the actual materials (e.g., "oil on linen"), the process you used (e.g., "glazing, sgraffito"), and the visual idea (e.g., "fragmented identity") within the 100-character limits. - Make sure the visual work shows that claim in every piece (preponderance of evidence across five works). - Show relationships: link how a material/process supports the idea (this is synthesis and raises Row C). - Test it: have someone who hasn’t seen your work read only your captions—can they match each caption to its image? If not, revise. For step-by-step tips and examples tied to the rubric, check the Topic 4.2 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX). For extra practice, Fiveable has many portfolio-related problems (https://library.fiveable.me/practice/ap-studio-art).

What does "visual relationships among materials, processes, and ideas" actually look like in real artwork?

“Visual relationships among materials, processes, and ideas” means that what you use and how you make something directly supports the concept you’re communicating—not random choices. For example: if your idea is “memory as decay,” you might use aging paper, tear and bleach processes, and layered collage so the texture, marks, and composition all evoke erosion. In a 2-D portfolio that shows that idea across five works, you’d use consistent 2-D skills (value, composition, figure/ground) while experimenting with materials (ink, coffee stains) and processes (rubbing, sanding) that reinforce the concept. For synthesis (Score 5) those relationships are strong and clear across the set: materials aren’t just listed in writing, they’re visibly integrated with processes and the idea in every image. For more examples and rubric language, see the Topic 4 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and the unit overview (https://library.fiveable.me/ap-studio-art/unit-4). Practice applying this to your works at (https://library.fiveable.me/practice/ap-studio-art).

I don't understand what "preponderance of evidence" means for scoring my portfolio - help?

“Preponderance of evidence” just means the score you get should reflect what most of your five Selected Works show—not whether every single work is perfect. Readers look across all five pieces and decide which score level most of your works support for the three criteria: A) written evidence, B) 2-D/3-D/drawing skills, and C) visual relationships among materials, processes, and ideas. If 3 of 5 pieces show “good” skills and synthesis, the preponderance supports a higher score even if 2 pieces are weaker. Remember: if your written labels are completely unrelated to the images, the portfolio can’t score above a 2. Use this quick check: for each criterion, count how many works clearly meet the level you think they do—the majority determines the score. For more detail, see the CED Selected Works rubric and the Topic 4.2 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX). Practice more samples at (https://library.fiveable.me/practice/ap-studio-art).

How do I make sure my 5 selected works show consistent skill level across all pieces?

Pick five works that all demonstrate the same level of technical control and clear synthesis of materials, processes, and ideas. Practically: - Start with the skill level you want (good vs. advanced) and only include pieces that visibly meet it across composition, mark-making/value (drawing), or 2-D/3-D principles. - Make sure your written idea for each work is actually visible in the image (the rubric rewards that) and that each caption identifies materials and processes (100-char limits). - Use similar or related materials/processes across pieces so visual relationships are consistent—that strengthens Row C (synthesis). - Revise weaker pieces or replace them; prioritize images that show clear craftsmanship and consistent skill across all five. - Photograph each work cleanly (no distracting backgrounds) so skills are obvious. For examples and scoring language, see the Topic 4.2 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and the Unit 4 overview (https://library.fiveable.me/ap-studio-art/unit-4). For practice, check the 1,000+ problems (https://library.fiveable.me/practice/ap-studio-art).

What's the difference between 2-D art skills and drawing skills in the rubric?

2-D art skills and drawing skills overlap but aren’t identical on the rubric. 2-D Art and Design skills refer to the full range of two-dimensional elements and principles—point, line, shape, plane, layer, color, value, texture, figure/ground, unity/variety, scale, etc.—and how you arrange them on a flat surface (this is what AP 2-D portfolios must demonstrate). Drawing skills are narrower: they focus on mark-making, line, surface, space, light and shade, and composition (the AP Drawing portfolio centers on these). So: if you’re in AP 2-D, show a broad use of elements/principles across media (graphic design, printmaking, collage). If you’re in AP Drawing, prioritize evidence of refined mark-making, tonal modeling, edges, and compositional choices. Both rubrics value synthesis of materials, processes, and ideas—make sure your written evidence matches the visual work. For more detail, see the Selected Works/Sustained Investigation rubrics (study guide: https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and practice problems (https://library.fiveable.me/practice/ap-studio-art).

Can I get a score of 5 if one of my pieces is weaker than the others?

Yes—you can still earn a 5 even if one piece is weaker, because scoring is based on the preponderance of evidence across the five Selected Works. To get a 5 you need: advanced 2-D/3-D/drawing skills (Row B), and strong synthesis of materials, processes, and ideas across the set (Row C). Written evidence must identify materials, processes, and ideas and be visually evident in the works. If four pieces show advanced skill and clear synthesis and your written statements link those ideas to the works, one weaker or inconsistent piece won’t automatically prevent a 5. However, if that weaker piece makes synthesis or skill unclear across the set, it can lower your score. Make sure every caption ties the idea to the visuals; that strengthens your overall preponderance of evidence. For tips and examples, check the Unit 4 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and other Unit 4 materials (https://library.fiveable.me/ap-studio-art/unit-4). For extra practice, see the AP Studio Art practice problems (https://library.fiveable.me/practice/ap-studio-art).

How long should my written evidence be for each selected work?

Keep each written entry very short and precise—the CED limits each field to 100 characters (including spaces). For every Selected Work you must fill: Idea(s) visually evident, Materials used, Processes used, Digital Tools, and Image Citation—each one has a 100-character maximum. So your “written evidence” for a single work is five separate short lines (up to 100 characters each), not long paragraphs. Make those lines clear and directly tied to the image (if the writing is unrelated, the portfolio can’t score higher than a 2). Use compact, specific phrases (e.g., “urban isolation,” “oil on linen,” “layered glazing, palette knife,” “Photoshop: color balance,” “photo: student, 2024”). For help tightening language and examples, check the Topic 4.2 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and more practice prompts at (https://library.fiveable.me/practice/ap-studio-art).

What does "coalescence/integration" mean and how do I achieve it in my art?

“Coalescence/integration” (aka synthesis) means materials, processes, and ideas visibly work together—each choice supports the concept so the viewer sees one unified purpose. For the Selected Works this means your five images should show consistent visual relationships among what you used (materials), how you made it (processes), and what you’re saying (ideas). A Score 5 needs a strong relationship among all three. How to achieve it: - Pick an idea and choose materials that naturally express it (e.g., fragile paper for vulnerability, rusted metal for decay). - Use processes that reveal meaning (tearing, layering, glazing, printing) rather than random techniques. - Repeat motifs, compositional strategies, color palette, or surface treatments across works so the idea is legible. - Make sure your written labels (idea/materials/processes) match what’s actually visible—AP reviewers check both. - Show advanced skills (composition, mark-making, value, form) and document decisive process choices. For examples and rubric tips, see the Topic 4 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX). For extra practice, try the AP Studio Art practice problems (https://library.fiveable.me/practice/ap-studio-art).

I'm struggling to show visual relationships between my concept and my materials - any tips?

Focus on making the connection between idea, material, and making visible in every work—not just in your written line. Start by picking 2–3 materials/processes that naturally express your idea (e.g., fragile paper for vulnerability, rusted metal for decay). Repeat a visual motif or gesture created by those materials across all five works so the relationship reads as synthesis, not coincidence. Use process-specific marks (tears, stitch, burn, layered collage) as evidence of the process and let those marks echo the concept. In your 100-character written fields, name the idea, materials, and processes clearly and exactly—if writing doesn’t match the images, your Selected Works can’t score above 2. Photograph details that show texture/process and include one full-view plus a close-up when needed. For more rubric-focused steps and examples, see the Topic 4.2 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX). Practice more portfolio-aligned work on Fiveable’s practice problems (https://library.fiveable.me/practice/ap-studio-art).

What exactly are they looking for when they say "strong evidence" versus "good evidence"?

“Good evidence” (Score 4) means your five works clearly show visual relationships among materials, processes, and ideas and demonstrate proficient (good) 2-D/3-D/drawing skills. The connections are observable across most pieces, and the written labels match what you show visually. “Strong evidence” (Score 5) means those relationships are consistently integrated—true synthesis—across all five works: materials, processes, and ideas coalesce so the viewer sees a unified, advanced handling of skills and concept. Practically: for a 4 you have clear intent and competent execution; for a 5 the execution is highly developed, the idea is visually evident in every piece, and the materials/processes aren’t just used—they’re purposefully transformed to support the idea. Remember the rubric uses the preponderance of evidence across five works and caps you at 2 if written evidence is unrelated (see the CED Selected Works Rubric). For more guidance, check the Topic 4 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and try practice problems (https://library.fiveable.me/practice/ap-studio-art).

How do I avoid getting marked down for having unclear visual evidence in my work?

Make the visual evidence undeniable: photograph and present work so materials, processes, and ideas are obvious and match your short written labels. Key moves: - Photograph carefully: even lighting, neutral background, in-focus, straight-on shots; for 3-D include two clear views (required). - Show detail images when a surface, mark-making, or process matters—these prove materials/processes and skill. - Compose so figure/ground, scale, and gesture read clearly; avoid distracting props or low contrast that hide form or texture. - Edit only to represent the finished work (crop, exposure, color-correct) and list any digital tools used—don’t use generative AI. - Make your 100-character idea/materials/process entries directly match what’s visible across all five works so viewers see synthesis of materials, processes, and ideas. For practical tips and photo examples tied to rubric language, check the Topic 4 study guide (https://library.fiveable.me/ap-studio-art/unit-4/sustained-investigation-rubric/study-guide/mtAtz22nuK6uCnQ0XtHX) and other Unit 4 resources (https://library.fiveable.me/ap-studio-art/unit-4).
