  Abstract: Empirical evidence regarding the effectiveness of any intervention is key for program improvement and evaluation, and the Learning Assistant (LA) Model is no exception. This presentation focuses on two lines of inquiry regarding the influence of the LA program at the University of Colorado Boulder--persistence to graduation and course-level D/F/W rates. We use logistic regression models to estimate the effects of exposure to the LA program on six-year graduation rates as well as course failure and withdrawal rates in large gateway STEM courses in two departments at CU Boulder. We find that the LA program has differential effects across departments and that both quantitative and qualitative investigation is necessary to understand the effectiveness of the LA Model. The presentation includes not only the relative results but also provides general information regarding the process for conducting this type of analysis, including an explanation of the models used in the analysis.
