Some schools in Christchurch have taken the unprecedented step of requesting special consideration of the marks for all students who sat NCEA exams this year.
The exams end on Wednesday and blanket applications have been made for the Qualifications Authority to compare students' marks to their internal assessments before deciding what results to give.
The 'derived grade process' would ensure students are not disadvantaged if the trauma and disruption caused by February's earthquake means they fail their exams.
Principals say as many as 12 schools have made blanket applications for their NCEA students.
The Qualifications Authority has not commented.
