From the summary:
While the results from pre-K education are well documented, the current funding and availability of early education varies widely. The recent recession has made it difficult for states to continue funding state-run pre-K programs, resulting in a decrease of $442 in the average state pre-K funding per child. Enrollment in state-run pre-k programs has remained relatively flat.
