An evaluability assessment (EA) of the 55 Alive program, a national older driver refresher course aimed at improving driving skills, was conducted. This EA adds to the evaluation literature as previous outcome evaluations neglected to explore whether this program was prepared for such assessments. A mixed-method protocol was executed across three community sites. Based on the results of this EA, several suggestions for future evaluations are discussed: (a) sampling all stakeholder levels for a more holistic snapshot of the program, (b) using EA to facilitate stakeholders' engagement in the evaluation, and (c) incorporating scientists specializing in the area within the evaluation.
