The demand for seats for 2-year-olds in an expanded public preschool program in New York City is far outpacing the spots available, raising questions about whether this approach will gather momentum in other parts of the country. There were nearly 5,700 applications for 2,000 new seats for 2-year-olds in the city’s pre-K program, which had already provided free, public preschool for 3- and 4-year-olds for a decade. Policymakers and educators have advocated for years for states and school districts to establish free, public preschool programs but few offer it for 3-year-olds. New York City offering free, public preschool to 2-year-olds is a big step, and one that some early childhood education advocates hope will lead to public programs for children starting at birth. Lessons New York City can take from New MexicoBoth New York City and New Mexico are attempting to make preschool available to a larger age range of children but have gone about it differently.
