As a society, are we investing enough in our youngest children? The BUILD Initiative's latest report, Early Learning Left Out, by CFPC director Charles Bruner, provides a clear answer that current investments fall far short. The report draws upon the most recent federal, state, and public school budget information--and what we know about effective investments in young children. It offers valuable information for those seeking to build early learning systems, based upon fiscal analysis and the latest research and evidence of the need for and value of additional investments in early childhood services. "Data Sources and Apportionment" is appended.
