This study was conducted to see if the engagement variables from the "TummySafe 2022" online course as well as the participants' demographic variables were positively correlated with the "TummySafe" certification exam score. The study examined factors that explained participants' exam performance. The results indicated that there was little to no correlation between demographics or engagement variables and the certification exam score. Findings indicated that 22.8% of the overall variance in certification exam performance was explained by number of prior certifications (10%), race (6.5%), gender (3.5%), ethnicity (0.2%), days between last course activity and exam (1.7%), in-course assessment (1%), total activity (2.3%), and page views (0.2%). Participants' in-course assessments and number of prior certifications were good indicators to predict if a student would pass or fail the certification exam.
