Objective Structured PRACTICAL Veterinary Examination Setting Pass/Fail score Linear Regression method Constant Group Size method

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

Marks Linear Regression method GP jp jf BF 3 2. 5 2 1 pass fail 4 Grades

Objective Structured PRACTICAL Veterinary Examination Linear Regression method 46. 8

Objective Structured PRACTICAL Veterinary Examination FAIL Pass 46. 8%=8. 5

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

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

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

Number of students Constant Group Size method with each mark, within grades. pass fail (Idealised) N set by assessor Nf & Np jp Total Number of candidates in each group remains jf constant BF n=n Marks

The End. Thank You
