The Build Back Better (BBB) framework would create an ambitious $400 billion early childhood initiative -- funding both universal prekindergarten for 3- and 4-year-olds and initiatives designed to improve affordability, quality, and compensation within the child care arena. On November 19, 2021, The Build Back Better Act (H.R. 5376) was passed in the House by a vote of 220-213 and is currently awaiting debate in the U.S. Senate. Based on the House Version and reflecting proposed amendments released by the Senate's Health, Education, Labor and Pensions (HELP) Committee on December 11, 2021, this guide is intended to familiarize policymakers with the major early childhood proposals contained therein.
