Early childhood education in Chattanooga, TN, is delivered through a mixed model that includes center-based, school-based, and home-based providers. The City of Chattanooga's Office of Early Learning, established in 2017, aimed to support each program delivery model in providing high-quality care to all children and families. To achieve this, they sought a uniform early childhood assessment tool that would provide detailed data on school readiness across different education settings. The previous observation-only assessment system was time-consuming and lacked sufficient data. They piloted Cognitive ToyBox to determine its effectiveness in assessing school readiness across the region. Study Goals: 1. To introduce a user-friendly, early childhood assessment tool common to all early learning providers in Chattanooga. 2. To understand school readiness holistically and identify areas for improvement. 3. To gather detailed student data (author abstract)
