The results of the longitudinal study are promising for the Arkansas Better Chance program. Overall, ABC students perform better on state assessments than children who did not attend ABC PreK. An important note for analysis of these results is the change in assessments over the study period. The Arkansas Benchmark test was used in 2013 and 2014, the PARCC was used in 2015, and the ACT Aspire was used 2016. (author abstract)
