The schools chancellor has promised to distribute high-needs students fairly across the school system. This comes after years of complaints from school communities that feel over burdened with high numbers of struggling and special-need students.

A record number of parents, student, and teachers responded to the city’s annual school survey.

Eighty percent of teachers said they received feedback on their teaching practices that helped them integrate the new Common Core standards into classroom instruction.

Chancellor Dennis M. Walcott said education officials would meet with the principals of 24 so-called turnaround schools on Tuesday afternoon to go over their budgets and help discern staffing needs, since recent hiring and firing decisions at the schools were reversed in late June by an arbitrator’s ruling.

Officials have identified 71 students who they said were involved in cheating during the administering of Regents exams at Stuyvesant High School last month, schools Chancellor Dennis M. Walcott disclosed on Monday during a radio interview. In all of those cases, the exam results will be invalidated and the students involved will have to retake the tests.

Most of the City Council’s 51 members have signed a letter urging the schools chancellor to lift the city’s ban on cellphones in public schools. The letter calls the current policy “inconsistent and possibly discriminatory” because it’s enforced mostly at schools with metal detectors.
