A testing company has admitted that it made additional errors on gifted and talented exams for city kids.
The Department of Education said Pearson made several mistakes in their grading formula.
It follows a similar disclosure of other errors on the same test, which affected nearly 5,000 students.
Because of the most recent mistakes, Pearson said that 82 students who did not initially qualify for gifted and talented programs actually did qualify.
64 students who qualified for district programs now also qualify for citywide programs, and 159 students were bumped into a higher percentile.
School officials said parents have been notified.
Chancellor Dennis Walcott said the problem is deeply disturbing, and that terminating Pearson's three-year contract is one of many options the DOE is considering.
