Schools and colleges are shut out from submitting teacher grades, just a day before the deadline, after an exam board’s submission portal crashed today.

OCR realised at lunchtime today that schools and colleges were unable to submit results to its grade submission system.

A spokesperson said “urgent action” is being taken to resolve the problem, but they said it “may take the rest of the day” to resolve.

The deadline for submitting grades is tomorrow (June 18). OCR said it “anticipates that all schools and colleges who would have submitted today will be able to submit tomorrow.”

A spokesperson said: “We would like to apologise to our schools and colleges for the inconvenience this is causing at such a busy time.”

Teachers also complained on Twitter this morning they were unable to access the AQA grades portal. AQA said it had “systems” issues, but tweeted that the portal for submitting grades was not affected.

The systems were up and running by 10am. AQA said the issue was caused by “a problem at an internet service provider that affected systems around the world”.
