9 Objective Structured PRACTICAL Veterinary Examination Timing Screens in all rooms with sound

10 Candidates given label with name/ number/ starting station number/ and then walked round the circuit Objective Structured PRACTICAL Veterinary Examination

11 Laboratory or examination room based. Objective Structured PRACTICAL Veterinary Examination

12 Preparing a patient for radiology (Hip) including up to taking the x-ray Objective Structured PRACTICAL Veterinary Examination

13 Gowning for closed gloving Objective Structured PRACTICAL Veterinary Examination

14 Objective Structured PRACTICAL Veterinary Examination Station 21: IM injection Cow (outside)

15 Objective Structured PRACTICAL Veterinary Examination Station 21: IM injection Cow (inside boxes) Box 1 Box 2

16 Station 22: Hoof Trim-Sheep

17 Station 1: Communication - horse history taking Objective Structured PRACTICAL Veterinary Examination No Flash to avoid startling animals Temp: 6°C

18 Station 1: Communication - horse history taking Objective Structured PRACTICAL Veterinary Examination

19 Station 1: Communication - horse history taking Objective Structured PRACTICAL Veterinary Examination

20 Station 1: Communication - horse history taking Objective Structured PRACTICAL Veterinary Examination

22 Station 10: Remove Horse Shoe Objective Structured PRACTICAL Veterinary Examination Ouch !

23 Objective Structured PRACTICAL Veterinary Examination Re-Shoeing Spares & Tools

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

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

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

27 46.8 Objective Structured PRACTICAL Veterinary Examination Linear Regression method

28 Pass FAIL 46.8%=8.5 Objective Structured PRACTICAL Veterinary Examination

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

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

33 The End. Thank You
