A system for on-site collection of evaluation data at a vehicle repair site installation is disclosed. Generally the system includes a mobile computing tool wirelessly connected to a database, a workflow operations guiding module that runs on the mobile computing tool, an evaluation module, a comparison module, a data-mining module, a certification module, a legal compliance module, and a repair procedure compliance module. As a vehicle is repaired, the workflow operations guiding module prompts a coach with questions. The evaluation module performs a quantitative analysis of the answers provided by the coach and the comparison module compares the result of the quantitative analysis against aggregated or averaged information. The certification module compares information from the comparison module against predetermined certification criteria and the data mining module identifies correlations, trends or patterns in collected data by the system.
