Comparing teacher effectiveness in high- and low-poverty schools
Blog by Stephen Sawchuk/Education Week
Teachers in high-poverty schools in Florida and North Carolina are on average only slightly less effective than those in low-poverty schools. However, within schools, the least-effective teachers in low-income schools are generally worse than the least-effective ones in more-affluent schools, according to a new analysis from the National Center for Analysis of Longitudinal Data in Education Research, or CALDER. What's more, such differences in effectiveness seem to be exacerbated by how things like teacher experience play out in the different types of schools. For example, additional years of teaching experience seem to improve a teacher's effectiveness in a low-poverty school, but less so in a high-poverty school, the analysis states. The bottom line of the study, according to the authors: Simply attempting to import teachers with great credentials into high-poverty schools probably won't make a long-term difference. Instead, "measures that induce highly effective teachers to move to high-poverty schools and which promote an environment in which teachers' skills will improve over time are more likely to be successful."
