Table 5 reports our findings for the period 2003–2011 and two sub-periods, 2003–2007 and 2008–2011. We selected these sub-periods in part because of the significant regulatory changes in 2006 and also to assure that we would have sufficient data for individual students within a sub-period to estimate models with student fixed effects. In fact, the basic findings are not sensitive to the specific sub-periods.

Notes: Entries in each cell come from separate regressions. The FE regressions include the charter school indicator, student FE, grade-by-year indicator variables, and seven time-varying characteristic of students, including lagged test scores. The value added models (VAM) include the charter school indicator, time invariant and time varying student characteristics, as well as grade-by-year indicator variables. “All” refers to the full sample; “switchers” refers to the set of students who switched between the charter and the traditional public school sector during the relevant time period.
