ATLANTA — An accrediting agency has placed Atlanta Public Schools on probation, giving the system nine months to start making improvements.

Mark Elgart, president and CEO of AdvancED, said Tuesday the board is "struggling to perform its roles and responsibilities on a day-to-day basis."

Elgart says the decision to place the school system on probation resulted from an onsite investigation and review. The review came after complaints that the board of education was not governing effectively.

Elgart informed the school system of the probation Tuesday morning before a news conference at AdvancED's headquarters.

Elgart stressed that the schools remain accredited during the probation, which applies only to the system's high schools.
