Cognitive accessibility covers people with learning disabilities, brain injuries, attention difficulties, and anybody reading in a second language, under stress, or in a hurry. Clear writing serves all of them and everybody else.

The part that gets skipped

Accessibility work concentrates on the technical layer, because it is checkable. Contrast has a number. Alternative text is present or absent.

Comprehension has no checker, so it gets left out, and a page can pass every automated test while being genuinely impossible for a large number of people to use.

Who that affects: people with learning disabilities or cognitive impairments, people with brain injuries, people with attention difficulties, people reading in a second language, older people, and anybody who is tired, distracted, stressed or in a hurry.

That last group is most of your visitors most of the time, which is why this is not a niche concern.

What actually helps

Unglamorous and effective.

None of this makes writing childish. It makes it faster to read, which is what a reader wants regardless of ability.

The jargon question

Where trades and professional services get it wrong in both directions.

Removing all technical vocabulary is not the goal, because the correct term is frequently the clearest one and customers do search for it.

What works is using the term and explaining it once, in the same sentence, in ordinary words. The reader who knows it skims past; the reader who does not is brought along.

What does not work is a page written entirely for peers, or a page so stripped of specifics that it says nothing.

The test is whether somebody could act on the page without already knowing the vocabulary.

Structure carries as much as wording

Frequently more.

A wall of text is hard for everybody and impossible for some. The same content with headings, short paragraphs and a list is the same words made navigable.

Headings matter twice over here: they let a screen reader user jump, and they let a struggling reader find the part they need without processing the rest.

Lists work because they remove the connective work. Steps in a numbered list are easier than the same steps described in a paragraph, even for a confident reader.

And the summary at the top of a long page is not padding. It is the version some readers will take, and the only version some readers can.

Instructions

Where clarity matters most and fails most.

One action per step. The trigger before the action, so somebody knows when to do it. No conditional branching mid-sentence.

What to avoid: sequences that mix instruction with explanation, so the reader is doing and understanding at once. Put the explanation before or after, not inside.

Deadlines, costs and requirements stated explicitly rather than implied, since a reader who has to infer something has to hold it in memory.

Reading level, honestly

Readability scores are a rough instrument.

They measure sentence and word length, which correlates with difficulty and does not measure it. A short sentence full of unexplained jargon scores well and is incomprehensible.

Useful as a signal that a page has drifted long and dense. Not useful as a target to write toward, because writing to a score produces choppy text that scores well and reads badly.

The better test is asking somebody outside the business to read the page and tell you what it says. Where they hesitate is where the problem is, and no score would have found it.

What this has in common with the rest

Everything on this list also helps a rushed customer on a phone, a search engine trying to understand the page, and a reader deciding whether to trust you.

Which is the recurring shape of accessibility work: the changes that help people with disabilities are almost always the changes that help everybody, and they are frequently the changes a copywriter would have recommended anyway.

The visual half of the same problem, meaning size, spacing and contrast, is covered in making text readable for everyone.

Frequently asked questions

Why does comprehension get skipped in accessibility work?

Because it has no automated checker. Contrast has a number; clarity does not, so a page can pass every technical test and still be unusable.

Who does plain language help?

People with cognitive impairments, brain injuries or attention difficulties, second-language readers, older people, and anybody tired, stressed or in a hurry.

Should I remove all technical terms?

No. The correct term is frequently clearest and customers search for it. Use it and explain it once in the same sentence in ordinary words.

Does structure matter as much as wording?

Frequently more. Headings let a screen reader user jump and let a struggling reader find the part they need without processing everything else.

How should instructions be written?

One action per step, the trigger before the action, and explanation before or after rather than inside the step.

Are readability scores useful?

As a signal that a page has drifted long and dense. Not as a target, since writing to a score produces choppy text. Ask somebody to read it aloud instead.
