Evidence you can act on, from the four WAC centres
Each paper reviews the best published research on one question, weighs the evidence on both sides, and ends with a framework and recommendations for universities, educators, edtech leaders and policymakers. Every claim carries a numbered source.

How these papers are written
They are desk research: a synthesis of peer-reviewed studies, working papers, official statistics and quality reporting. WAC ran no survey or trial for them, and they say so. Each reference was opened and checked against the claim it supports before publication, the strongest counter-evidence is included, and figures we calculated ourselves are marked.
- Sources listed in full, with links
- Charts drawn from the cited data
- An original framework in each paper
- Recommendations for four audiences
