Usage Guidance
-
This metric is intended to capture the efficiency of teachers employed by the school as a proxy for the quality of education provided. Studies have shown that experience has the strongest impact over the first few years of teaching, after which marginal returns diminish. Research also shows that high-poverty schools tend to have a greater proportion of teachers with fewer than three years of experience.
