Over 100 appeals have already been lodged since last night with exams body CCEA who produced the grades for each student.
Principals across Derry have been furious over how CCEA had awarded the grades, describing the who proccess as a “shambles”.
But CCEA and the DUP Education Minister Peter Weir have defended how the grades for each student were reached.
One of those principals not happy with the grading system which will lead to appeals is Katrina Crilly of Oakgrove Integrated College.
She said: “We are forgetting the fact that principals are under pressure to get COVID restarts – and get everybody back on the premises.
“Where are the resources coming from to manage all these appeals?”
Pupils going into years seven, 12 and 14 are to return to school on 24 August with all other pupils returning from 31 August.
But despite readying for the return of pupils for the first time since March, a dedicated team now needs to be set aside at her school “to process appeals only out of already strained resources,” she says.
Katrina Crilly said principals feel “like general dogs bodies” whose integrity was “questioned when it came to the results we submitted”.
