Nearly one in five leaving cert students will receive a grade lower than their school's estimated result for them.
The cabinet's agreed not to use schools’ track records to determine how students would've done, if they'd sat the State exams.
83 per cent of students are due to receive a grade based on their teachers’ estimate, or higher, while 17 per cent will get below the school prediction.
An additional 1,250 higher education places are being created for the class of 2020.
Students are welcoming the decision by government to remove the school's previous performance from the grading system.
Former student at St Mel's College in Longford, Luke Casserly is waiting for his results to be issues next Monday.
He is also the Vice President of the Irish Second Level Students Union.
Luke says the change will mean alot more weight will be given to the grades provided by teachers and that's a good thing.
