What a Book Accessibility Check Can and Cannot Prove

An automated accessibility check can identify conditions its rules are designed to detect. It cannot establish that every reader can understand and use the book. Review the actual exported format, test meaningful reading tasks, and describe the evidence precisely instead of treating a passed report as universal approval.

Start with a reading task and the delivered format

Accessibility review becomes more useful when it begins with something a reader needs to do. A reader may need to find a chapter, understand a chart, follow a sequence of instructions, or distinguish a warning from surrounding explanation. Write down those tasks before interpreting a report. Otherwise, a list of passed checks can become detached from the book's purpose.

Keep the format explicit. A printed workbook, a fixed-layout file, and a reflowable ebook present different reading experiences. KDP provides format-specific preparation guidance, so evidence gathered from one deliverable should not be casually transferred to another. A comfortable desktop reading experience does not tell you whether a printed exercise has usable space or whether another version presents information in a sensible order.

Read each result as a statement about a particular rule

When a tool reports a problem, identify what it inspected and what condition triggered the result. When it reports a pass, identify the same boundaries. A checker might establish that an image has an associated text field without judging whether that text communicates the image's purpose. These are different questions, and both can matter to the reader.

Consider a chart that compares three stages of a process. The phrase “process chart” identifies the object's general type but may omit the comparison the reader needs. A technically present description can still leave the teaching task unfinished. Record the automated result separately from the editorial judgment about whether the explanation conveys the necessary information.

Look for meaning that depends on appearance alone

Read the book's instructions while deliberately questioning references to color, shape, and location. Phrases such as “choose the green option” or “continue with the box on the right” can become ambiguous when the presentation changes or the visual distinction is difficult to perceive. Ask whether a stable label or a direct description would help the reader identify the same item.

This does not mean every visual detail needs a long textual repetition. Determine what the detail does. A decorative flourish may have no role in understanding the lesson, while the direction of an arrow may define the order of a procedure. Preserve the information needed to complete the task and remove unnecessary references that make the explanation depend on a fragile visual arrangement.

Test navigation and reading order with a complete example

Choose a chapter containing several different elements: headings, a table, an illustration, and a reader exercise. Follow the intended route through that chapter in the exported file. Check whether references lead to identifiable destinations and whether explanations appear before the task that depends on them. A well-organized source document is useful evidence, but the exported result is the deliverable readers encounter.

If a specialist or reader uses assistive technology to review the book, agree on the tasks and record the file version and reading environment. Their findings can reveal important problems without becoming a claim about every possible device or reader. Keep observations concrete, such as a missed heading or an unclear relationship between a question and its answer choices, so the author can make and verify a correction.

Distinguish content corrections from technical repairs

Some findings require rewriting. An instruction may assume a visual distinction that the text never explains. Other findings may require changes to document structure or export settings. Record these as different repair tasks so a formatting adjustment is not mistaken for a completed explanation, and a clearer paragraph is not assumed to repair the underlying file structure.

After a repair, repeat the relevant reading task in the new export. Also examine nearby material when the change affects layout or navigation. For example, replacing a diagram with a longer explanation may move an exercise away from its introductory instructions. The revised paragraph can be accurate while the chapter becomes harder to follow, which is why the result needs another contextual read.

Keep the final claim proportional to the evidence

A release record can say that a named checker ran against a particular file and that identified issues were resolved or documented. It can also describe the manual tasks reviewed. Those statements are more informative than a vague claim that the entire book is accessible. Avoid suggesting certification, comprehensive coverage, or universal compatibility when no such assessment occurred.

Preserve unresolved findings with their practical consequences and next steps. If an important task remains difficult in a planned format, address that problem before relying on a favorable summary score. The purpose of the review is to improve the reader's ability to use the book. A report supports that work when its boundaries remain visible throughout editing and release preparation.
