According to NZQA, NCEA is the only secondary school qualification worldwide where marked examination papers are returned to students. After the examination papers have been returned, a student can apply for certain papers to be reviewed if a marking or clerical error has occurred (e.g. the paper has not been fully marked, the marks have been added up incorrectly, the examination paper shows a different result from their results notice), or they can apply for certain papers to be remarked ("reconsidered") if they feel they have not been assessed correctly. To prevent students cheating, any blank writing space is crossed out by markers before the papers are returned, and students cannot request a review or reconsideration on any paper where they have written in pencil or used correction fluid.
