Does Teaching Experience Increase Teacher Effectiveness? A Review of the Research

This paper reviews 30 studies from the past 15 years on the effect teaching experience has on student outcomes and concludes that teaching experience is positively associated with student gains, both on standardized testing, and on other measures, including attendance. The report finds that student gains are steepest in a teacher’s earliest teaching years, but can continue into their second and third decades in the classroom, and that teachers are more effective when they work in a supportive and collaborative environment or accumulate experience over time in the same grade level or subject.
