Almost 2,000 learner drivers in NI failed their driving test for at least the fifth time last year.
Environment Minister Edwin Poots told the assembly that 14,744 car drivers failed on their first attempt.
SDLP MLA Thomas Burns, who tabled the question to the minister, urged people who failed several times to persevere.
"Many people find the process tough going, but candidates should not view their difficulties as a sign of them being a personal failure," he said.
Of people taking their second test, 11,126 were unsuccessful, while 5,839 failed for a third time, 2,608 failed their fourth attempt while 1,981 failed five or more times.
