The College Board disclosed Wednesday that 27,000 SAT college entrance exams missed being rechecked following the initial discovery of scoring problems, with the result that another 375 students were given incorrectly low marks.
In a news release, the College Board said that last week it asked Pearson Educational Management, which scores the exam, to confirm all 495,000 October tests had been rescored; that request followed an earlier oversight in which 1,600 exams were overlooked.
Last weekend, Pearson notified the College Board that 27,000 tests from the pool of October exams still had not been reevaluated. They have since been rescored.
The announcement is the latest in a string of disclosures that have infuriated students and sent college admissions offices scrambling. It brings to 4,411 the number of students who received incorrectly low scores.
The College Board said that from now on, working through Pearson, it would scan each answer sheet twice and take other scoring precautions. It also said it would retain Booz Allen Hamilton, a consulting firm, to perform a comprehensive review within 90 days.
