In order to pass the OSCE candidates must obtain the overall pass mark for the OSCE, where Law and skills are weighted equally. The interview and attendance note are also weighted equally.
The pass mark will be set using the borderline group method. In essence an overall view is taken of whether or not a candidate reaches the standard of a newly qualified solicitor in England and Wales. The mark of those candidates who are judged borderline is then used to determine the pass mark. A correction will be made for error measurement in the test using standard psychometric procedures (SEm).
In this way a pass mark which is empirically justified is established. Following the examination the OSCE will be reviewed statistically to confirm its reliability (co-efficient alpha) and accuracy (SEm). Equality impact assessments will be conducted as appropriate. The marking of the OSCE will be subject to review by External Examiners appointed by the SRA.
