Setting Pass/Fail score
Linear Regression method
Constant Group Size method

25. Objective Structured PRACTICAL Veterinary Examination
Objective ‘Marks’
1 per action= 10 – 40 in different stations
Subjective Grades
Grade 4 = Good Pass
Grade 3 = just pass
Grade 2 = just fail
Grade 1 = Bad Fail

26. Marks 4 GP 3 jp 2 jf 1 BF pass fail 2.5 Grades
Linear Regression method

27. Objective Structured PRACTICAL Veterinary Examination
Linear Regression method
46.8

28. Objective Structured PRACTICAL Veterinary Examination

46.8%=8.5

29. Objective Structured PRACTICAL Veterinary Examination
Linear Regression not work well with skewed marks as this station

30. Constant Group Size method
Student’s are subjectively assessed as grades 1 to 4.
The number of student’s attaining each Grade is counted. The cut; Pass/fail mark is set so that the number of students passing and the number failing is the same as that subjectively determined by the assessor.
Good for stations with skewed marks

31. Number of students with each mark, within grades. (Idealised)
Constant Group Size method
The problem is where to set the ‘cut’ mark? jp
Total Number of candidates in each group remains constant jf BF
