With an increased demand arising from stake holders to provide more complex clinical experiences and to have students better prepared for clinical rotations, educators need to develop instructional tasks and measures to teach and assess clinical reasoning. The purpose of this article is to highlight a clinical simulation measure revolving around the A SECRET reasoning approach, which is also generalizable to other conditions and interventions. Preliminary findings of 1st year Master of Occupational Therapy students (n = 8) who took part in a pilot of the A SECRET case scenario reported positive, yet not strong, attitudes toward the A SECRET assessment and the sensory processing related content delivered in an online format as a part of a larger study. Overall the student perceptions and the processes of the measure development suggest an inherent value of using the proposed type of simulated case scenarios in assisting occupational therapy students in their program's first year with the development of clinical reasoning.
