Grades for thousands of Illinois students in East Aurora School District 131 could be incorrect because of the faulty setup of an online grading system.
Officials say the problems occurred in the last seven semesters. The district will change past grades only if they improve when corrected. Current-semester grades could rise or fall if they’ve been incorrectly tabulated, however.
The error occurred, officials said, when dozens of teachers missed a step in setting up online grade books.
