Context: Mental workload is a concept used in many industries to investigate operator performance, but it has only recently been used in the educational setting. It has been suggested that excessive mental workload in assessors may impair the validity of objective structured clinical examination (OSCE)-type assessments.
Objectives: This study aimed to establish the feasibility of measuring the mental workload of examiners during an OSCE assessment and to establish methodologies and baseline values to guide future study design.
