Poland's Central Examination Commission received reports that an hour before tests on Polish literature started on Tuesday morning, there was a spike in internet searches for one of the topics in the exam.
The head of the examination commission, Marcin Smolik, said that if there had been a leak, he suspected that the source could be a head teacher with "a really strange notion of how to help" pupils.
"This needs to be checked," he added.
Smolik said that if the school in which the leak took place was identified, the exams taken there would be declared void and the culprit would be charged.
Poland's matura school-leaving tests are a rite of passage and determine teenagers’ future to a large degree.
