Abstract

A non-transitory computer readable medium contains an evaluation program that causes a computer to perform steps of obtaining a vehicle stability score of vehicle driving skills based on measured data, obtaining a turning performance score of the vehicle driving skills based on the measured data, obtaining an overall evaluation result of the vehicle driving skills based on the vehicle stability score and the turning performance score using conversion information, and conveying the overall evaluation result to an output unit. The conversion information defines the overall evaluation result such that the overall evaluation result decreases as the turning performance score increases if the vehicle stability score is lower than a threshold and such that the overall evaluation result increases as the turning performance score increases if the vehicle stability score is higher than the threshold.
