What makes a strong inquiry for a Sustained Investigation, and how do guiding questions keep it generative all year?
Developing an inquiry: form a specific, generative question that can drive a sustained body of work, and break it into guiding questions that direct practice, experimentation and revision.
A focused answer on the AP Art and Design inquiry: how to write a specific, generative central question for the Sustained Investigation, why broad themes are not inquiries, and how to break the inquiry into guiding questions that direct each new experiment so the body of work develops rather than repeats.

What this topic is asking
The Sustained Investigation, 60 percent of your score, must be driven by an inquiry: a question you investigate through making. Skill 1 (inquiry and investigation) starts here. A strong inquiry generates a year of distinct, related experiments; a weak one (a broad theme) leaves you repeating yourself. This page is about writing a question that can carry a body of work.
A theme is not an inquiry
Themes like "the ocean", "memory" or "identity" are starting points, but on their own they cannot be investigated, because they raise no question. The College Board wants a question that demands making to answer it. Compare:
- Theme (weak): "Identity."
- Inquiry (strong): "How can fragmented self-portraits, built from torn photographs and stitched thread, express a divided sense of identity?"
The second tells you what to test (fragmentation, tearing, stitching) and lets a reader see whether each new piece answers the question better than the last.
What makes an inquiry generative
A good inquiry sits in a useful middle ground:
- Specific enough to direct you. It should suggest materials, processes and the kind of image you will make.
- Open enough to sustain a year. It must allow many different experiments, not one idea repeated 15 times.
- Visually answerable. It should be a question your artwork, not an essay, can investigate.
Guiding questions
An inquiry is the big question; guiding questions are the smaller questions that direct each new piece. They are how you avoid the trap of repeating the same image. If the inquiry is "How can layered, partly erased surfaces make a paper image feel weathered by time?", guiding questions might be:
- Which removal processes (sanding, bleaching, scraping) age a surface most convincingly?
- Can erasing part of a finished image suggest loss of memory rather than just damage?
- What happens if I build a surface up, then strip most of it back to a trace?
Each guiding question becomes one or more experiments, and the answers push the next question.
Why this matters
The inquiry is judged twice: directly, through written evidence prompt 1, and indirectly, through whether your 15 images form a coherent, developing investigation. An investigation with no clear question reads as a folder of unrelated pieces and caps the inquiry score; a sharp question with visible development reads as exactly what the rubric rewards.
Try this
Q1. State the difference between a theme and an inquiry. [Recall]
- Cue. A theme names a topic but asks nothing; an inquiry is a specific, generative question that can be investigated through making.
Q2. Turn the theme "the sea" into a strong inquiry and one guiding question. [Short explanation]
- Cue. Inquiry: "How can salt-crystallized and water-stained paper turn a drawing of the sea into an object the sea itself has marked?" Guiding question: "Does drying salt water on the paper before or after drawing change how the stain reads?"
Exam-style practice questions
Practice questions written in the style of College Board exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
AP 2024 (written evidence, style)5 marksSustained Investigation written evidence prompt 1 asks you to identify the inquiry that guided your sustained investigation (600 character maximum). Write a response that would let a reader see your inquiry clearly, then explain why it scores well.Show worked answer →
Written evidence prompt 1 is the single most important sentence in the portfolio, because it tells the reader what to look for across all 15 images.
A strong response identifies a specific, generative question, not a topic: "My investigation asks how the surface of a city wall, its peeling posters, graffiti and decay, can become a record of forgotten time. I explored layering, sanding back and partial erasure on paper and board, testing how built-up and removed surfaces could make an image feel weathered and historical."
Why it scores: it names a clear question (Skill 1, inquiry), points to the materials and processes the reader will see, and is framed so that experimentation is possible. A weak response ("My investigation is about cities") names a topic with no question and gives the reader nothing to track.
AP 2023 (written evidence, style)5 marksExplain why the theme 'nature' would be a weak inquiry for a Sustained Investigation, and rewrite it as a strong inquiry with two guiding questions.Show worked answer →
"Nature" is a subject, not an inquiry: it raises no question, so it cannot drive experimentation or revision, and a reader cannot tell whether the body of work develops.
A strong rewrite turns it into a question that demands testing: "How can pressed and decaying plant matter be used to print images that change as the material breaks down?" Guiding questions then direct each experiment: (1) "Which plants leave the strongest print, and how does drying time affect the mark?" (2) "Can I revise a print by reprinting over it as the original plant decays, so the image records its own decay?"
Markers reward a question specific enough to generate distinct experiments and guiding questions that show how the investigation will move forward rather than repeat one idea.
