Sixth form enrolment software provider Applicaa is investigating after its system “crashed” on GCSE results day.
The firm has apologised after its platform “disrupted” the enrolment process for nearly 300 schools until around 2pm on Thursday.
A spokesperson said they were “acutely aware of the gravity of today’s system disruption, especially during such a pivotal period”.
Although the system was rigorously tested in advance it “clearly fell short of the actual amount of stress it was put under,” they added.
