What do the two Sustained Investigation written responses have to do, and why can weak writing cap an otherwise strong portfolio?

Sustained Investigation written evidence: answer the two prompts (identify the inquiry; describe development through practice, experimentation and revision) within the 600 character limit so the writing identifies materials, processes and ideas and unlocks the full score range.

A focused answer on the two Sustained Investigation written responses: prompt 1 (identify your inquiry) and prompt 2 (describe development through practice, experimentation and revision), each capped at 600 characters. Explains the decision rule that writing which fails to identify materials, processes and ideas can cap the portfolio at the lower score points, and how to write both prompts well.

What this topic is asking

The Sustained Investigation is not only images. You also submit two short written responses, each capped at 600 characters including spaces. Skill 3 (communication) is scored here, and a decision rule means weak writing can cap an otherwise strong portfolio. This page covers what each prompt asks, the gating rule, and how to write both within the tight limit.

The two prompts

  • Prompt 1 (inquiry). State your guiding question and the materials, processes and ideas you used to investigate it. This tells the reader what to look for across the 15 images.
  • Prompt 2 (development). Show the investigation moving: a thing you practiced, a thing you experimented with, a thing you revised, each tied to something visible in the images.

The gating decision rule

This is the most consequential fact about the written evidence. It means the writing is not decoration: it is a gate. The fix is simple but easy to forget under the character limit, you must explicitly name materials, processes and ideas.

Writing within 600 characters

Six hundred characters is roughly three to four sentences. There is no room for warm-up or feeling-words; every clause must carry information.

Why this matters

Readers score the images, but they read the writing first and apply the gate. A student who writes "My art is about my feelings and I tried lots of things" has, in one sentence, capped a portfolio they spent a year on. A student who names lint, fixative and the idea of absence has unlocked the full range before the reader even studies the images. The writing is the cheapest points in the course to win or lose.

Try this

Q1. State what each Sustained Investigation prompt asks and the character limit. [Recall]

  • Cue. Prompt 1, identify the inquiry; prompt 2, describe development through practice, experimentation and revision; each limited to 600 characters including spaces.

Q2. Explain in one sentence why "My work explores my feelings about home" is a risky prompt 1 response. [Short explanation]

  • Cue. It identifies no materials or processes and only a vague idea, so it risks failing the decision rule and capping the portfolio at the lower score points.

AP 2024 (written evidence, style)5 marksWrite both Sustained Investigation written responses for an imagined investigation into how household dust and lint can be used as a drawing material, staying within roughly 600 characters each, and explain how they support each other.
Show worked answer →

The two responses work as a pair: prompt 1 sets the question, prompt 2 shows it moving.

Prompt 1 (inquiry): "My investigation asks whether the dust and lint a home sheds can become a material for drawing absence, the trace of people who are no longer there. I fixed collected lint to paper with diluted glue and matte medium to build soft, gray, fragile images of empty rooms."

Prompt 2 (development): "I practiced fixing lint without flattening its fibers, then experimented with sieving it for tone and pressing it through stencils. When glue darkened the lint too much, I revised by spraying fixative from a distance, which held the fibers while keeping their pale gray."

Why it earns credit: both responses identify materials (lint, glue, fixative), processes (fixing, sieving, stencilling) and an idea (absence), which unlocks the full score range, and prompt 2 names practice, experimentation and revision with visible results.

AP 2023 (written evidence, style)5 marksExplain the decision rule that links the Sustained Investigation written evidence to the available score points, and what it means for how you must write.
Show worked answer →

The rubric uses a gating decision rule: if the written evidence does not identify materials, processes and ideas, the portfolio is only eligible for the lower score points; if it does identify them, the portfolio is eligible for the full range.

A strong answer draws the consequence: no matter how strong the images are, vague writing that never names what you used, what you did and what it means can cap the whole Sustained Investigation. So the writing must be concrete and must explicitly identify materials, processes and ideas, not just describe feelings or effort.

Markers reward an answer that treats the writing as a scored gate, not a formality, and that knows the fix is specific identification within the 600 character limit.
