The Department of Education says oral and practical tests for the upcoming State exams are being cancelled.
Instead, Leaving and Junior Certificate students will be awarded full marks.
The deadline for submission of project work and coursework in a number of subjects has also been pushed out to May 15th.
The department says the decision was taken in light of the closure of schools as a result of the COVID-19 virus.
The change means all students who were due to take oral and practical performance tests will be given full marks.
This include oral tests in Leaving Cert Irish and the modern languages (French, German, Spanish, Italian, Russian and Japanese).
It also covers practical performance tests in Leaving Certificate music, as well as Junior Certificate music and home economics
