If they hadn't been mostly shut out of bids to run a slew of new L.A. Unified campuses, the groups might have demonstrated how they handle students with challenging needs.
Los Angeles school officials lost a chance this week to test whether the booming charter movement can take on all the problems of the district's traditional, and often troubled, schools.
On Tuesday, the Board of Education denied proposals from three major charter organizations that had sought to run newly built neighborhood schools, which would have included substantial numbers of limited-English speakers, special education students, foster children and low-income families.
That is exactly the population that charter schools have been criticized for not sufficiently reaching.
Charters are independently managed and exempt from some rules that govern traditional schools. They're also schools of choice -- campuses that parents seek and select. And researchers have found that charters enroll fewer students with more challenging, and often more expensive, needs.
