This report presents the first year (2015-16) findings from the impact evaluation. Its focus is on children's learning, the classroom quality they experienced, and how learning varied with differences in experiences. In addition to describing these findings for SPP, the report presents comparable findings from other preschool studies including the Head Start Family and Child Experiences Survey (FACES) to contextualize the results. The report also presents findings regarding children's attendance. Although the first year population served is very small and the data come from only 14 classrooms, we present findings for subgroups of students and classrooms as well as the full sample.
