Multi-level random-effects meta-analysis of 88 knowledge effect sizes from 50 studies of professional development for in-service teachers. The pooled effect was "a large effect ( g = 0.93 [0.76; 1.10])", with no difference between self-rated knowledge and tested knowledge.

"The analysis of knowledge showed a large effect ( g = 0.93 [0.76; 1.10]), with no difference between self-rated knowledge ( g = 0.96 [0.70; 1.22]) and kno wledge assessed using tests ( g = 0.91 [0.68; 1.15]"
