A vendor demo is designed to impress, not to inform a purchase. The buyers who avoid regret are the ones who ask for evidence before the contract, and know how to read what comes back. This guide sets out the evidence to request from an edtech vendor, using an appraisal table that separates each claim from the study design, population, comparator, effect and transfer limits behind it. It is not about auditing bias in edtech platforms, which is covered separately.

Ask for claims you can check

A useful evidence request names the exact claim, the study behind it, and the setting it was measured in. Vague "proven results" cannot be appraised. The What Works Clearinghouse publishes standards and procedures for judging the strength of education evidence. [c-wwc] Asking a vendor to map claims to designs, in that language, quickly reveals how much evidence actually exists.

A request list that separates signal from pitch

• Outcome evidence: independent studies, with design and comparator, not testimonials or logo walls.

• Population match: evidence from learners and settings like yours, since transfer is not automatic.

• Interoperability: how the tool exchanges identity and results with your systems rather than trapping data.

• Accessibility conformance: a current, specific statement against a known standard, not a general promise.

Interoperability and accessibility are evidence too

Integration and access are not separate from the evidence; they decide whether a result can even apply to your learners. Learning Tools Interoperability defines how a platform and an external tool exchange identity and results securely.

[c-wcag] is one whose claimed results will not reach every learner you serve.

Where DoviLearn® fits

A platform described under DoviLearn® for organisations can be held to the same request list: ask for the claim-to-design mapping, the interoperability and accessibility statements, and how they fit your platform and technology . The standards and the judgement stay with educators and organisations, and the example shows a process rather than guaranteed learning, employment or business outcomes.
