CCE: Why is grading system better than marks system?
Students scoring 71, 75 or 79 marks will be awarded the same grade. Is it justified? In what ways are grades better than marks?
Awarding of grades has number of advantages over awarding of numerical marks. It considerably reduces inter and intra examiner variability in marking. It also takes care of imperfection of tools used for assessment. Statistical research in assessment techniques indicates that there is a possibility of variation of scores awarded to individuals to the extent of 5% to 15%. Putting students of similar potential in same ability bands (grades) automatically takes care of all these abbreviations in assessment techniques. Lastly, it will reduce undesired and unsound comparison of small difference of marks.
