BACKGROUND: Objective structured clinical examinations (OSCEs) are used frequently in course subjects owing to their utility in determining the students' clinical competencies under a variety of simulated conditions. In the University of the Philippines (UP) College of Pharmacy, the use of a summative OSCE has already been used as a form of assessment in some of its courses. However, previous batches of students felt unprepared for their summative OSCE at the end of the semester. In particular, students reported unfamiliarity with the content and format of the said examination. To address this concern, formative OSCEs were conducted in a Pharmacy laboratory course.

OBJECTIVE: This study aimed to evaluate the effect of the feedback component of formative OSCEs on the students' self-perceived learning and achievement of the course outcomes, facilitating knowledge, skills and attitudes development towards the course, and preparing them for the summative OSCE. It also sought to identify useful aspects of the formative OSCEs and how they can be improved further.

METHODOLOGY: Four formative OSCEs were administered from January to May 2017 to all fourth-year pharmacy students taking Pharmacy 154 (Dispensing and Incompatibilities). The units covered were: (1) extemporaneous and sterile compounding; (2) over-the-counter (OTC) medicines and prescription drugs; (3) dangerous drugs and medical devices; and (4) therapeutic incompatibilities and medication safety. After each formative OSCE, feedbacks were provided to the students. Once all OSCEs were conducted, an online, self-administered questionnaire consisting of four parts was given to the students. Total population sampling was employed in the study. The responses (n = 44) were analyzed using frequency statistics. Thematic analysis was done for the aspects of the formative OSCEs that were most useful, and how they could be further improved.

RESULTS AND CONCLUSION: The frequency analysis of responses from the questionnaire generally showed that the students had positive perceptions to the feedback component of the formative OSCEs. Still, there was no significant association found between passing the summative OSCE and the formative OSCEs owing to the differences in the content of each examination. Overall, formative OSCEs may be a good assessment tool to track the students' progress and give them constructive feedback in terms of the competencies expected in the course and to better prepare them for the summative OSCE. Increasing the time allotted for each station and orienting them better prior to formative OSCEs were the commonly suggested points for improvement.
