Inside This Unit: The Full Breakdown
Unit 3 explains the Sustained Investigation (60% of the portfolio): a cohesive body of 3-D work that develops a guiding inquiry through practice, experimentation, and revision, with written evidence of that development.
Why it matters
The Sustained Investigation is the largest and most distinctive part of the portfolio — coherence and evidence of development raise scores.
Key concepts
- Sustained Investigation = a developing inquiry, not unrelated finished objects.
- Show practice, experimentation, and revision over time.
- Written evidence names the inquiry and how the work evolved.
Sustained Investigation
Frame a specific yet open inquiry you can explore through materials, sequence images to show evolution, include experiments and revisions (even unsuccessful ones), and write clear evidence of inquiry, practice, experimentation, and revision.
AP exam tip
Pick an inquiry you can explore through multiple materials and forms — too narrow or too vague stalls the investigation.
