Pupils taking GCSE, AS and A-level exams in 2023 will know the topics they will be questioned on ahead of testing.
The approach in Northern Ireland is similar to that already announced in Scotland and Wales.
In a letter to school principals, Education Minister Michelle McIlveen said the move would help to support pupils and increase their confidence.
It is similar to changes to exams brought in for summer 2022 to account for disruption due to Covid-19.
But Ms McIlveen said that pupils would study and be tested on all parts of GCSE, AS or A-level courses in 2023.
