"A Little Now for a Lot Later: A Look at a Texas Advanced Placement Incentive Program" examined whether the Advanced Placement Incentive Program (APIP) affects students' SAT/ACT scores and college attendance. The research described in this manuscript is consistent with the What Works Clearinghouse (WWC) evidence standards with reservations. Strengths recognized by WWC include: Used differences in the timing of APIP implementation across schools to estimate effects. The following cautions were identified. The study compared schools that had implemented APIP to those that had not yet done so. It also examined whether a school's outcomes improved after APIP implementation. Schools implementing APIP early and later in the study period may have differed in ways not controlled for in the analysis. In addition, APIP may have been more likely to be implemented in schools that were about to improve anyway--because of new school leadership, for example. If so, the study might have produced misleading results.
