The probability of graduating BRPC according to demographic predictors is shown in Figure 3. Dotted line reflects the average probability of graduating. Points and error bars represent the probability of selection for each demographic category with 95% confidence interval. Age was a strong predictor of BRPC successful completion. The youngest Marines (18–20 years) had a < 50% probability of success whereas Marines greater than 22 years of age had >50% probability of success. Education was also a strong predictor; a college degree was associated with a greater than 60% chance of BRPC completion whereas only a high school degree had less than a 50% chance of success.
