q3 · i2 · review · r2

A study of 250,000 North Carolina middle school students over five years using teacher fixed effects found clear returns to experience through at least 12 years, with printed effect sizes of 0.08 standard deviations in ELA and "0.18 standard deviations in math" versus a novice teacher, per the review's summary.

"A teacher with 12 years of experience raised test scores from 0.08 standard deviations in ELA to 0.18 standard deviations in math as compared to a teacher with no prior experience."

q3 · i0 · review · r2

The same middle school study found returns level off after 12 years, yet printed an effect size showing "math and ELA teachers with 21–27 years were still 0.04 standard deviations more effective" than at five years of experience; this printed effect size of 0.04 standard deviations is below d = 0.2.

"Although the returns level off after 12 years for math and ELA teachers, the study found that math and ELA teachers with 21–27 years were still 0.04 standard deviations more effective than when they had five years of experience."

• 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 — related
• In a North Carolina high school study with teacher fixed effects, achievement returns to experience rose up to 20 years, from about 0.06 SD at 1–2 years to about 0.27 SD beyond 27 years — related
• 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
