Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? The benefits of professional development for student mathematics gains are significantly larger for principals with 3 or fewer years of experience, with significant differentials for managing change, leading instruction, and developing people. → Campoli 2022 q3 i? These differentials by principal experience level do not appear when the outcome is student gains in English language arts. → Campoli 2022

Evidence

Campoli 2022

Campoli, A. K., & Darling-Hammond, L. (with Podolsky, A., & Levin, S.). (2022). Principal learning opportunities and school outcomes: Evidence from California. Learning Policy Institute. https://doi.org/10.54300/438.376

q3 · i? · associational · r2

Interaction analysis (Table 5) of professional development components by principal experience group for mathematics gains. The main effect for principals with 3 or fewer years is 2.186* overall, with managing change at 2.685*** and developing people at 1.8*; the 4–9 years and 10+ years groups show negative relative coefficients (e.g., managing change -2.048 and -1.79*), meaning their professional development experiences are associated with smaller gains than those of inexperienced principals. No standardized effect size is printed.

"The greater benefits for early-career principals are statistically significant for professional development associated with managing change, leading instruction, and developing people."
