A supplier has delivered the film and agreed companion files. Your organisation now needs an independent view of whether the intended experience meets its accessibility requirements. What should you purchase: a caption check, a media review, a player assessment or a wider evaluation?
Those engagements answer different questions. Before comparing fees or accepting an “accessibility checked” statement, define what the evaluator will examine and what evidence your organisation needs from the work.
Independent evaluation can provide a separate assessment from the people who produced or implemented the material. Independence alone does not establish competence, sufficient coverage or a particular result. The scope and method still need scrutiny.
Name the decision the evaluation will support
Explain why the assessment is needed. You may be deciding whether a new video is ready for a specified public page, investigating a reported barrier or obtaining evidence required by an internal procurement policy.
Obtain the actual requirement, including its version and the person responsible for interpreting it. Do not ask a consultant to guess what your organisation means by “fully accessible”. Equally, do not turn a limited review into a promise of compliance with every possible obligation.
Separate the evaluation result from the authority to publish. A specialist can report findings; your organisation still needs a named owner who decides how those findings affect release or remediation.
Define the experience being bought and tested
Identify the exact film, language versions, companion files and viewing destinations in scope. A downloadable file, an embedded website player and a social-platform upload can present different experiences even when they contain the same picture edit.
Ask whether the engagement covers the media content, the player controls, the surrounding route to required alternatives or a defined combination. Include access to any restricted staging page through your approved process. Do not assume a public link and a private preview behave identically.
If only a sample of a larger library will be examined, record how the sample will be chosen and what conclusions it can support. A report on one film should not be presented as an assessment of every video your organisation holds.
Ask what the evaluator will actually do
W3C's evaluation overview explains that tools can assist, but cannot alone determine whether a website meets accessibility standards; knowledgeable human evaluation is needed. A dashboard result should therefore be described as the evidence it is, not treated as a complete judgement by default.
Ask the prospective evaluator to explain its method in relation to your scope. What will people inspect? Which tools or assistive technologies will inform the work? Will participation by users with relevant disabilities be included, and what will that activity establish?
These are questions about the proposed engagement, not a universal testing recipe. The appropriate specialist should explain the limitations and required expertise. Do not substitute a checklist of technology names for a coherent method.
Request findings that can guide a purchase or correction
A useful report should make its scope and evidence traceable. Ask how findings will identify the affected version, location or time range, the observed issue and the requirement being assessed. Discuss how the evaluator will distinguish a confirmed finding from a question needing further information.
Also ask what the report will say about limitations. Missing access, untested destinations and excluded versions should be visible. A short summary may help decision-makers, but it should not conceal the basis for the conclusion.
Clarify whether remediation advice, production consultation and a later check are included. Evaluation, fixing an issue and confirming the fix are separate pieces of work even when one supplier can provide several of them.

| Field | What to specify or ask |
|---|---|
| Purpose | Decision the organisation needs the evaluation to support |
| Requirement | Exact target and its authorised internal owner |
| Content set | Video identifiers, languages and companion material |
| Destinations | Pages, players or other viewing arrangements to examine |
| Method | Human assessment, supporting tools and any user involvement proposed |
| Deliverable | Report structure, evidence references and stated limitations |
| Exclusions | Material or experience the engagement will not assess |
| Correction route | Who receives actionable findings and who commissions changes |
| Retesting | What will be checked again, under which scope and after what evidence |
Before accepting the engagement, ask for an explanation of relevant experience and, where shareable, a representative reporting format. You do not need another client's confidential findings to understand how the supplier communicates results.
A hypothetical comparison between two quotes
Imagine a property business requests an accessibility check of a project film on its website. One proposal covers the accuracy and timing of the supplied captions. Another covers defined media requirements and the implemented player experience, with a stated retest allowance.
Neither proposal is inherently wrong. The first offers a narrower service. If the buyer's actual requirement includes operating the player and accessing essential visual meaning, the caption-only review does not answer the complete question.
The buyer clarifies the intended scope before comparing the proposals. It may appoint a specialist for the wider evaluation and retain the caption review as a separate production check. This invented example illustrates scope comparison, not actual supplier pricing or a guaranteed assessment outcome.
Preserve the limits when communicating the result
When reporting internally, identify what was evaluated, when and against which requirement. Do not turn a qualified report into a broad “certified accessible” marketing claim. Changes to the film, companion material or player may require further assessment; agree that decision route with the responsible people.
Use the existing accessibility requirements worksheet to organise the production brief. If an evaluation identifies work needed on a construction film, contact Live Images with the relevant findings and version. Ask which production changes can be scoped while keeping specialist assessment and release authority explicitly assigned.
