↵Notes: Standard errors reported in parentheses; * and ** indicate significance at the 5 percent and 1 percent levels, respectively. Standard errors clustered at the school level. Outcome variable: age-11 (Key Stage 2) national standardized test scores. Each column reports results from an OLS model estimated for schools rated Fail in the years 2006 to 2009. Prior ability percentile calculated using age-7 (Key Stage 1) mathematics and writing tests. Students with missing age-7 test scores dropped from the sample. All regressions include full set of student- and school-level controls; see notes to Table 3 for details. Regressions in Columns 1 and 3 also include prior ability percentile as control; regressions in Columns 2 and 4 include prior ability quartile.
