In this report the authors examine high school completion and postsecondary enrollment (a.k.a. "educational attainment") of the cohort of 9th grade students who were in the Milwaukee Parental Choice Program (MPCP) at the beginning of their state-mandated evaluation of the MPCP in 2006. After tracking the MPCP 9th graders following the 2006-07 year and comparing them to a carefully matched sample of 9th graders who were in Milwaukee Public Schools (MPS) during the 2006-07 year, they use a combination of parent surveys and administrative (school) records to estimate attainment. Overall, the primary finding of this report is that MPCP students had slightly higher rates of attainment than their MPS counterparts. This difference is primarily explained by the fact that more MPCP than MPS students both graduated from high school and enrolled in a four-year college. Some of the MPCP attainment benefit appears to be due to family background, as the attainment differences between their MPCP and MPS samples become smaller and lose statistical significance when they control for such factors as mother's education, income, two-parent families, and religious attendance in attending a two-year or technical college. Students in both sectors were far more likely to graduate and enroll in college if they remained in their initial sector (always in MPCP or always in MPS) from 2006-07 to 2009-10. This effect was stronger than any other attainment outcome they estimated, although it was particularly strong for MPCP students. Appended are: (1) Covariates and 2010 Graduation Survey Response Information; and (2) Other Model Results: Ordered Probit Estimates of Overall Attainment.
