To support high quality learning environments and alignment of effective instruction to student success, all children in First Class Pre-K classrooms are assessed using Teaching Strategies GOLD(R), an ongoing, observation-based, research-validated assessment system. Grounded in current research related to child development and learning, the Teaching Strategies GOLD(R) assessment includes 38 objectives across six domains of development (social-emotional, physical, language, cognitive, literacy, and math) that are associated with school success based on school readiness standards. The purpose of this issue brief is to examine school readiness and growth among students who received First Class Pre-K during the 2015/2016 school year. (author abstract)
