This Race to the Top - Early Learning Challenge (RTT-ELC) annual performance report for the year 2014 describes Colorado's accomplishments, lessons learned, challenges, and strategies Colorado will implement to address those challenges. As outlined in the grant statement of work, Colorado is implementing the following projects and has identified if there are other state departments involved in managing or receiving grant funds, including the grant monitor role for each project area: (1) Overall Grant Management; (2) Early Learning and Development Guidelines; (3) Next Generation Tiered Quality Rating Improvement System; (4) Building a Great Early Childhood Workforce; (5) Results Matter Expansion; and (6) Kindergarten Readiness/School Readiness. Lessons learned include: (1) The aggressive time line of the Race to the Top - Early Learning Challenge Grant requires government systems to move quickly; (2) Communication is critical; (3) Engaging early childhood professionals and local implementation partners while designing and developing new systems is critical; and (4) Successful implementation of an authentic, observation-based school readiness assessment is dependent, in part, on support from principals and school district administration.
