The Office of the Assistant Secretary for Planning and Evaluation, in partnership with the Administration for Children and Families within the U.S. Department of Health and Human Services, funded Mathematica Policy Research and its partners to conduct the Learning About Infant and Toddler Early Education Services (LITES) project. LITES aimed to identify program models to support infant and toddler early learning in out-of-home early care and education settings to inform future research, policy, and program directions at the federal, state, and local levels. LITES included two main components: (1) a systematic review of the evidence base for program models that aim to support infant and toddler early learning; and (2) a scan of the field for program models that are compelling, but currently lack rigorous research examining impacts on children’s outcomes.
This report summarizes the methodology for the LITES systematic review. To learn more about the systematic review findings, please refer to Monahan et al. 2015.
