Adapt the access, not the thinking: a before-and-after task rewrite

A student can understand the science and still get stopped by the page. They can see the mathematical relationship and still struggle to write the explanation. They can have a defensible interpretation and still lose it inside unfamiliar vocabulary, a crowded layout, or a response format that measures more than the curriculum asked for.

The answer is not to make every task easier. It is to separate the thinking you need from the barrier you accidentally added.

Before adapting a task, write two sentences:

1. The thinking students must do is…
2. The evidence I need to see is…

Change the route only after those are clear. Adapt the access, not the thinking.

A task contains more than one demand

Imagine this Grade 7 science prompt:

Read the two-page article. Then write three paragraphs explaining how the removal of one species could affect the rest of the food web. Use at least six vocabulary terms.

The intended curriculum demand may be causal reasoning about ecosystems. But the task also demands sustained reading, vocabulary retrieval, paragraph organization, handwriting or typing, and enough working memory to coordinate all of them.

Some of those demands may belong. Others may be accidental.

If the goal is to assess independent reading comprehension, replacing the article with an audio summary would change the evidence. If the goal is to assess ecosystem reasoning, however, the print density may be blocking students from showing the thinking you actually need.

That distinction comes first. There is no universally accessible format and no adaptation that is right regardless of the goal.

Step 1: name the cognitive demand with a verb

Return to the expectation or learning goal and identify what students must do: explain, compare, model, justify, evaluate, design.

Then finish this sentence:

A successful response must show that the student can…

For the ecosystem task:

A successful response must show that the student can trace a change through at least two connected parts of a food web and explain why each effect follows.

Now you have something to protect. Word count, handwriting, vocabulary quantity, and independent decoding do not get to become hidden requirements unless they are part of the stated learning.

Step 2: locate the barrier

Do not begin with a label about the student. Begin with the point where the task blocks useful evidence.

Ask:

• Can the student perceive the information: see it, hear it, distinguish its important parts?
• Can the student make meaning from the language, symbols, examples, and assumed background knowledge?
• Can the student hold and organize the steps long enough to complete the task?
• Can the student express the required thinking through the response mode?
• Is the task asking for a skill that the learning goal does not actually require?

CAST's Universal Design for Learning Guidelines 3.0 organize practical options across engagement, representation, and action and expression. CAST also makes an important point in its guidance: a tool or alternative format is not automatically “UDL.” It matters only when it reduces a barrier in service of a clear, challenging goal.

Step 3: change one layer at a time

There are four useful places to adapt a task.

Change how information is available

You might provide:

• a text with clearer spacing and headings;
• audio alongside—not automatically instead of—the text;
• a diagram connected to the same concepts;
• a glossary for vocabulary that is not itself being assessed;
• a worked example that shows the structure without supplying the answer.

Change how the work is organized

You might:

• reveal the task in stages;
• separate planning from producing the final response;
• use a checklist that names the decisions, not every tiny action;
• let students rehearse an explanation before recording it;
• reduce copying and unnecessary switching between pages or apps.

Change how students can respond

When the response format is not the target, students might show the same reasoning through:

• a written explanation;
• an annotated diagram plus a short explanation;
• an audio or video response;
• a teacher-recorded conference;
• manipulatives or a model accompanied by an explanation.

The response can vary. The evidence cannot quietly disappear.

Change the support, then plan to remove it

A sentence starter, partially completed model, word bank, or prompting question can make a first attempt possible. But a scaffold should have a job and an exit.

The OECD's 2025 synthesis on formative assessment and adapting to student thinking notes that scaffolds are not automatically beneficial; they require deliberate use in response to a specific need. It also frames adaptive teaching as keeping expectations high while varying the route and support.

Write down what you will watch for and when you will reduce the support. Otherwise, a temporary bridge can become a permanent ceiling.

Before and after: the ecosystem task

Before

Read the two-page article. Then write three paragraphs explaining how the removal of one species could affect the rest of the food web. Use at least six vocabulary terms.

After

Use the article, audio, and food-web diagram to examine what may happen if the frogs disappear. Show a chain of at least two effects. For each arrow in your chain, explain why the first change could cause the next. You may respond with an annotated diagram and explanation, a written explanation, or a recorded explanation. Use the scientific terms that make your reasoning precise.

The revised task changes several access conditions:

• information is available through connected text, audio, and visual representations;
• the causal chain is visible as the structure of the response;
• students can choose a response mode when writing fluency is not the target;
• vocabulary serves precision rather than an arbitrary quota.

The thinking is not lower. In fact, the evidence requirement is clearer: two connected effects, each justified.

Two more quick rewrites

History: compare sources

• Hidden barrier: two dense sources use unfamiliar syntax and vocabulary.
• Protected demand: compare how the sources represent the same event and use details to explain a difference.
• Adaptation: preserve both sources, add chunking, audio, a small vocabulary note, and a side-by-side evidence organizer. Accept an oral or written comparison. Do not reduce the task to listing one fact from each source.

Mathematics: justify a comparison

• Hidden barrier: the task requires a full written paragraph before students can show their fraction reasoning.
• Protected demand: compare two fractions and justify the relationship using a valid representation.
• Adaptation: offer fraction strips, a number line, or a drawing tool; allow the justification to be spoken and recorded. Do not replace the comparison with simpler fractions that remove the intended challenge unless the numbers—not the reasoning—are the barrier you are deliberately addressing.

Run the equivalence check

Before giving the adapted task, compare it with the original.

1. Same verb: Are students still explaining, comparing, modelling, justifying, evaluating, or designing?
2. Same important content: Are they reasoning with the concepts the curriculum requires?
3. Same evidence threshold: Would success convince you of the same learning?
4. Fewer accidental barriers: Did you remove difficulty that was unrelated to the goal?
5. No answer embedded: Does the support open the task without doing the thinking for the student?
6. A plan to review support: Will you notice when the scaffold can change or fade?

If the answer to the first three questions is no, you may have changed the target rather than the access. That can sometimes be an appropriate decision, but it should be deliberate, locally authorized, and described honestly—not hidden inside a worksheet rewrite.

One boundary worth keeping visible

This framework is general instructional guidance, not individualized special-education or legal advice. Required accommodations, accessibility plans, individualized plans, assessment rules, and terminology vary by jurisdiction and learner. Follow the student's documented plan and consult the appropriate specialist or local authority when it applies.

The practical principle remains: make the goal clearer, locate the barrier precisely, vary the route with purpose, and preserve the evidence that matters. Students do not need every task to look the same. They need a fair opportunity to do the thinking the curriculum actually asks for.
