Concerned with potentially compromising the test's integrity, College Board is not making the SAT available online this year and asking universities to loosen admissions requirements.

As many as 16,400 students will be required to retake their exams as confusion over file formats and other technical difficulties muddied the launch of a new online service offered by the College Board.

The standardized testing company College Board says it's preparing to put the SAT online and to help students who don't have access to broadband or devices.
