The human brain develops rapidly in the first five years of life. High-quality early learning experiences can have a profound and lasting positive effect on young children during these years, setting the stage for success in kindergarten and beyond. This is especially true for young children with high needs who are from low-income families; who have disabilities or developmental delays; who are English learners; who reside on "Indian lands"; who are migrant, homeless, or in foster care; and other children as identified by the State. The Race to the Top--Early Learning Challenge (RTT-ELC) program, authorized by Congress in 2011, is designed to improve the quality of early learning and development programs for young children. The RTT-ELC grants support States' efforts to design and implement an integrated system of high-quality early learning programs and services. RTT-ELC States submit Annual Performance Report (APR) data to ED and HHS each year as a requirement of the grant. In the spring of 2014, Phase 1 States and Phase 2 States submitted their APRs for 2013, their second and first APRs, respectively. This summary report provides information about the progress the 14 Phase 1 and Phase 2 States reported in their APRs for 2013. This report provides information from the 14 States about the impressive progress they are making in reforming their early learning and development systems. The document describes some of the initiatives that 14 RTT-ELC States undertook in the first or second year of their grants, as reported in their Annual Performance Reports (APRs). It is not intended to be a comprehensive look at all the activities and progress States have made to date. Yet even in this short period of time and in this brief report, it is clear that the RTT-ELC grantees are making progress toward improving the quality of early learning and development programs in their States and providing access to these high-quality programs for more children with high needs. These efforts are moving States toward the RTT-ELC goal of providing more children from birth through age 5 with a strong foundation that is needed to succeed in school and beyond. The infusion of funding, coordinated technical assistance from RTT-ELC, and firm timelines are giving States the needed impetus to develop a systems-based approach to improving the education and development of their youngest citizens.
