The City of Chattanooga's Office of Early Learning serves as a strong model for collaboration across early learning programs. By utilizing a uniform assessment tool and fostering cross-program collaboration, they developed inclusive communities of practice, and ensured a smooth transition for children from Head Start into Kindergarten. The study highlights the benefits of data-driven decision-making and the importance of collaboration between Head Start and public schools.

The pilot of Cognitive ToyBox was successful, providing early childhood leaders with better insights into school readiness and areas for improvement. The implementation expanded to support over 2,000 children across different early childhood education programs. The use of the assessment tool facilitated cross-program collaboration and allowed the city to monitor school readiness and respond quickly to educators' and families' needs. The data-driven decision-making approach led to collaborative adjustments and improved program effectiveness. Additionally, the implementation created a digital portfolio for each student entering Kindergarten, providing a clear picture of their developmental strengths and areas for improvement.
