WASHINGTON (AP) — The District of Columbia’s inspector general has found that cheating on standardized tests occurred at one school in 2010 but has found no evidence of widespread cheating across the school system.

The inspector general’s report was released Wednesday. It found at least one teacher at Noyes Education Campus coached students toward correct answers on tests.

Inspector General Charles Willoughby wrote that there was “insufficient basis” to warrant investigating other schools as thoroughly as Noyes.

Schools Chancellor Kaya Henderson said in a statement that she hopes the report will put to rest suspicions of cheating.

The investigation began after USA Today reported unusually high numbers of erasures from wrong to right answers at more than 100 district schools. The federal Education Department is also investigating.
