A method and system for recertifying an interactive computer simulation station from certification rules provided by an authoritative source. A baseline results of the station, generated upon certification thereof is obtained. While executing a simulation in the station, tangible instruments are stimulated in real-time for generating subsequent test results. Deviated parameters are identified with a test result incompliant with a target value. For the deviated parameters, a previously certified deviated value is obtained from the baseline results. A previously accepted deviation value is computed. A challenged deviation value is computed between the test result value, the target value and the baseline value. A delta deviation value is computed between the previously accepted deviation value and the challenged deviation value. When the delta deviation value is within the acceptable deviation range, the deviated parameter is identified as an equivalent parameter and the original justification from the baseline results is associated therewith.
