 Axios - California is missing out on $810.7 million in federal education funding that was expected to be accessible on July 1 but has yet to be released by the Trump administration.

The Department of Education's funding delay has exacerbated the uncertainty for after-school, summer and other programs, leaving schools in limbo, advocates and policy experts say.

• The Education Department said in a last-minute notice that the funds would not be released while the programs were under review, according to the School Superintendents Association.

By the numbers: Some $6.2 billion in K-12funds across five programs remains unavailable to schools across the country, according to the Learning Policy Institute.

• That includes funding for after-school and summer learning to support migratory children, educator development funds and more.

California is among the states that could be most critically hit since about 16.5% of the state's overall federal K–12 funding could be at risk.

Threat level: If unreleased 21st Century Community Learning Center funds — the chief stream for academic enrichment outside of school hours — remains blocked, "the fallout will be swift and devastating," Boys and Girls Clubs of America President and CEO Jim Clark said in a statement.
