A driving diagnosis apparatus temporarily records a diagnosis result of the user before changed when a user is switched, and starts to diagnose the user after changed. Accordingly, since driving status of each user is independently diagnosed, the diagnosis result is proper. Further, when a driving distance of the vehicle is smaller than a threshold, the diagnosis result of a driving interval is not recorded so that the driving interval is removed from an object of giving a point. Influence to environment is also considered in evaluation of the driving status. Accordingly, in the driving diagnosis apparatus and a driving diagnosis system for diagnosing driving status and for evaluating a driver based on the diagnosis result, the diagnosis and the evaluation are properly performed.
