WebNov 17, 2024 · 1 Cut score or cut point is a minimum achievement or ability that examinees should get in order to get a 'Pass'. In CTT, MCQ scoring in the form of percent-correct scores are applied. Let say we determined 50% and above as 'Pass' (cut score) and less than 50% is 'Fail'. Then, if an examinee gets 40/80 marks, he will get a 'Pass' result.
