Evidence

Leonard Tetzlaff, Florian Schmiedek & Garvin Brod. (2021). Developing Personalized Education: A Dynamic Framework. Educational Psychology Review. https://doi.org/10.1007/s10648-020-09570-w

q3 · i0 · review · r2

The review reports meta-analytic evidence for formative assessment (learning progress assessment / curriculum-based measurement), quoting 'several meta-analyses reporting effect sizes' with the printed value d = 0.32 in regular classrooms and higher effects for special educational needs. All procedures share dynamic, individual assessment of learning progress.

"This has been shown in several meta-analyses reporting effect sizes of d =0 . 3 2 in regular classrooms (Kingston and Nash 2011), and higher ones for students with special educational needs (Jung et al. 2018)."
