This last report from Mathematica's evaluation of Upward Bound analyzes data from the final round of survey and transcript data collection as well as administrative records from the National Student Clearinghouse and the federal Student Financial Aid files. It provides the first estimates of the effects of Upward Bound on postsecondary completion. The report also updates previous estimates of the program's effects on postsecondary enrollment and receipt of financial aid. Except for a statistically significant increase in the likelihood of earning a postsecondary certificate or license from a vocational school, the report finds no detectable effects on postsecondary outcomes, including enrollment, financial aid application or receipt, or the completion of bachelor's or associates degrees. In addition to these results, the report includes the findings from extensive subgroup and sensitivity analyses. Nine appendices are included: (1) Sample Design, Unit Nonresponse, and Weights; (2) Data Collection and Outcome Measures; (3) Sensitivity Analyses Pertaining to the Measurement of Outcomes; (4) Sample Sizes and Weighted Standard Deviations for all Outcome Variables; (5) Estimation of Impacts and Standard Errors; (6) Methods used to Estimate the Effects of Additional Upward Bound Participation; (7) Sensitivity Analyses Pertaining to Sample Weighting; (8) Other Supplemental Service Programs; and (9) Additional Subgroup Tables. (Contains 17 tables, 1 figure and 32 footnotes.)
