This Race to the Top - Early Learning Challenge (RTT-ELC) annual performance report for the year 2015 describes New Jersey's accomplishments, lessons learned, challenges, and strategies New Jersey will implement to address those challenges. New Jersey's remarkable progress in increasing participation in their tiered quality rating and improvement system, STARS, and the number of programs in the top tiers of STARS, is due to the collective impact of many public/private, cross-sector initiatives. Notable efforts include close collaboration among New Jersey Birth to Five, the Child Development Division (CDD), and the cross-agency implementation team of Act 166 led by the Agency of Education. The report provides details on accomplishments that: (1) improved quality and access of early learning and development opportunities; (2) improved early childhood wellness; (3) invested in a highly skilled workforce through professional development; (4) empowered communities to support young children and families; and (5) strengthened New Jersey's data systems to ensure that New Jersey is making a difference. Lessons learned pertained to financial management, flexibility to promote innovation, and creating stronger linkages between regional and state level work.
