I'm trying to find a report of federal early childhood education funding levels by state, by year. Any ideas?
ED.gov's State Fact Sheets on Proposed Federal Funding for Preschool for All is the report you are seeking. These reports are all about "Increasing Access to High-Quality Early Childhood Education", divided by state, and include federal funding data:

not what you asked for
this resource library has data, essentially comparing each state's performance (or lack thereof), as well as local government activities/spending and comparisons. Its actually really high quality data.
