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 · i2 · review · r2
A statewide study of North Carolina high school students over four years; initial analyses showed gains largely in the first two years, but teacher fixed effects models comparing each teacher to him or herself over time printed effect sizes of about "0.27 standard deviations" for teachers with more than 27 years versus about 0.06 standard deviations at 1–2 years.
"a teacher with 1-2 years of experience raises student achievement by about 0.06 standard deviations, while a teacher with more than 27 years of experience raises student achievement by about 0.27 standard deviations."
Discussion¶
Related Claims¶
- A Florida study found experience effects in elementary and middle school math and reading up to 0.16 SD for teachers with 15–24 years, but no returns to experience for high school teachers — reports the opposite
- In a North Carolina middle school study, a teacher with 12 years of experience raised scores 0.08 SD in ELA and 0.18 SD in math versus a novice teacher, with returns persisting through 21–27 years — related
- Teachers improve faster when they teach the same grade level and subject for multiple years — related
- Teacher improvement is fastest in the first five years of teaching — a broader claim this one bears on
- Teaching experience is positively and significantly associated with student achievement gains throughout a teacher's career, per a review of 30 studies — a broader claim this one bears on
