Subclaims¶
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.
q2 i? The study used a multi-state regression discontinuity design to estimate impacts of school entry age on growth through second grade. → Angela Johnson 2020

Discussion¶
Related Claims¶
- The early academic advantage of entering school older may fade in later grades, per a multi-state regression discontinuity analysis through second grade — possibly the same claim (merge candidate)
- Being a year older at kindergarten entry leads to higher initial achievement — related
- Prior evidence on school entry age lacked causal estimates of growth through early grades — related
