Summative assessment takes place after learning has been completed
and provides information and feedback that sums up the teaching and
learning process. Typically, no more formal learning takes place at
this stage, other than incidental learning from feedback and results.
If a student fails a summative assessment, they are usually granted an opportunity to re-take the assessment. They are also often awarded a capped grade - i.e. they cannot be awarded a mark above a predetermined level, and this will therefore influence the overall grading of their degree.
If the student passes an assignment first time - is it right to then allow them a chance to get a better grade (i.e. resubmit), if there is no complaint about the original award?
