EdWorkingPapers: Open Education Research

Free open-access working-paper series from the Annenberg Institute at Brown University with Stanford's SCALE Initiative — early education research with strong policy implications, downloadable before journal publication.

Why I recommend it: If you work in education or workforce programs, citing a current working paper makes a proposal much harder to dismiss.
