The purpose of this study was to determine if an association existed between student achievement scores and classroom practices used among third-grade teachers in Upper East Tennessee. The variables included classroom environment, instructional context, and social context, employing developmentally appropriate practices (DAP). Teacher characteristics, including type of degree, highest degree, years of experience, level of DAP knowledge, and degree granting institution, were analyzed for characteristics influencing developmentally appropriate practices. The instrument, Assessment of Practices in Early Elementary Classrooms (APEEC), was used to gather information; the Tennessee Comprehensive Assessment Program (TCAP/CRT) Reading/Language and Mathematics scores were used to determine students’ achievement level. A demographic survey was used to collect teacher characteristic information.
