There could be many reasons why the Board for Teaching and Testing of South Asian Languages does not return marked examination scripts to students ("Parents petition for return of exam scripts"; June 20).

Perhaps there are subject areas where there is only a limited number of questions that can be used in examinations and there is a need to keep these confidential.

It could also be an extra administrative burden on staff if exam scripts are returned.

However, exceptions should be made for students, especially those who failed or obtained poor grades.

With the scripts, they can better analyse their performance with parents or tutors.

The Ministry of Education should set guidelines on the return of examination scripts. It should at least explain why marked exam scripts are not returned.

Hopefully, it is not because of the fear that parents will contest the fairness of the marking or appeal for a review of results.
