This retrospective study examined the predictive ability of cognitive and non-cognitive factors, including grit, on first attempt pass rate on the National Board for Certification in Occupational Therapy exam. A convenience sample of 226 graduates from six cohorts of one occupational therapy program was used. Binary logistic regression revealed that grit was not a significant predictor. Program grade point average and verbal and quantitative Graduate Record Examination scores were independent predictors of passing on the first attempt. These findings can be used to identify at-risk students who could benefit from support to increase student success on the licensure exam.
