This descriptive and cross-sectional study used literature review and structured observation as data collection methods. Students’ performances were assessed using checklists by 4 examiners in 27 OSCE stations. Stations 24-27 were manned and stations 1-23 were in written format. Statistical analysis was carried out using SPSS computer packages. The written stations were too many in proportion to the clinical stations for an OSCE. The mean scores in the stations were between 5-78% and pass mark was set between 0-97percent. The tasks were either too easy or too difficulty in 26%(7stations, n=27) of the stations, the variance was generally too high for a criterion referenced test and none of the means was centrally located. Station 19 was extremely difficult. Examiners’ error was moderately high at 66%, stability was too high (Alpha was 0.6, ideal is up to 0.5) and internal consistency ranged from -0.4 to 0.6 (alpha) . Gcoefficient was low at 0.22. Item analysis was good in 30%(8) but poor in 19%(5) of the stations. The analysis recommended that 19% of the stations was to be discarded, 52% of the stations to be reviewed and 30% of the station (whose properties were good) were to be banked for future use.  \nKeywords: OSCE scores, SPSS computer packages  \nINTRODUCTION  \nThe objective structured clinical examination (OSCE) is increasingly being used as a major method of clinical assessment in sub Saharan Africa, yet its psychometric characteristics have not been well documented because its implementation can be challenging especially in resource limited institutions [1] . A number of issues (such as station length which may be too short to achieve reliable results, how to define pass/fail criteria, to mention a few) have been raised about how well the OSCEs practiced in resource limited medical schools is able to measure knowledge and skills necessary for competent clinical practice. The quality assurance machinery in place in most medical schools currently, involves mainly human raters which can be subjective, biased and inconsistent [2] . Psychometric analysis, offers a stable, objective and cheap means of measuring and improving consistently  \nthe quality of the OSCEs and all other forms of assessments [3] .  \nA lot has been documented and published about the psychometric qualities of the OSCEs practiced in the Medical Schools of the developed countries, but even there, psychometric analysis has not yet been incorporated into the University policies for r","cbCaiq1EwP8g1gGR","https://ap.wps.com/l/cbCaiq1EwP8g1gGR","pdf",388512,"English","# Introduction\n# Methods","[{\"question\":\"What was the purpose of this study?\",\"answer\":\"To describe the psychometric properties of July 2015 Paediatrics OSCE scores with the goal of improving assessment.\"},{\"question\":\"How was student performance assessed?\",\"answer\":\"Students were assessed using checklists completed by four examiners across 27 OSCE stations, with written and manned station formats.\"},{\"question\":\"What statistical and evaluation approach was used?\",\"answer\":\"Statistical analysis was conducted using SPSS.
