Bryk<\/p>\n\n\n\n<p>Heterogeneity of program effects has become a central concern in educational field trials. Increasingly, studies seek to measure \u201cfidelity of implementation\u201d as a key moderator for variation in effects across sites.<\/p>\n\n\n\n<p>Often the programs under study are quite complex by design (e.g., involving multiple work roles, processes, and tools that interact with one another). They also confront a wide range of local contextual and organizational conditions. This has caused me to ponder, \u201cUnder what conditions is the idea of fidelity of implementation an appropriate conceptual organizer\u2026.&nbsp;<em>Read the full blog post&nbsp;<\/em><a
