The 2013-2014 North Carolina Pre-Kindergarten (NC Pre-K) Evaluation study was designed to examine the longitudinal outcomes through kindergarten for children who attended the Pre-K program, along with comparisons to previous cohorts of program attendees. A sample of 561 children was included in the study, with data gathered at the beginning and end of NC Pre-K (2012- 2013) and kindergarten (2013-2014) to examine their growth in skills. Researchers conducted individual assessments of children's language, literacy, math, and general knowledge skills and gathered teacher ratings of behavior skills. For 119 Spanish-speaking dual language learners (DLLs) in the sample, parallel assessments were conducted in both English and Spanish to examine their progress when measured in both languages. In addition, program characteristics and services were examined for the 2013-2014 NC Pre-K Program using data from the statewide databases, as well any changes over time since the program became statewide in 2003-2004. Information about the observed quality of classroom practices was obtained from NC rated license assessments of a sample of 374 NC Pre-K classrooms conducted by the NC Rated License Assessment Project (NCRLAP) in 2013-2014.
