Detroit teachers return to uncertain future

News media reported that Detroit’s teachers returned to work May 5 after officials promised they would be fully paid for their work. But the system still expects to run out of cash in June, and it is not clear where the salary funds will come from. The district faces problems not unfamiliar across the country. Thirty-one states still have failed to raise per-pupil spending to pre-recession levels. Charter schools also have introduced competition.
