The world of EdTech evaluation and evidence is complex and the Needs-Based Evidence Mapping report provides a practical framework for clarifying what evidence is needed, by whom, and for which decisions across the EdTech ecosystem.

Built around a five-domain model, the report organises evidence according to purpose rather than methodological hierarchy. Instead of asking whether a product “has evidence”, the framework asks: which decisions does this evidence meaningfully inform — and which does it not?

The report argues for a shift from a narrow focus on “proof of impact” toward a broader culture of “proof of trust”: evidence that is credible, context-sensitive, explainable and socially responsible. Impact evidence remains important, but on its own it cannot address questions of pedagogical fit, usability, equity, safety, implementation feasibility or long-term sustainability.
