The objective of the invention is to provide a driving evaluation system which can evaluate driving skills in a transitional period of acceleration, a driving evaluation method, a program, and a medium. The driving evaluation system evaluates driving skills of a vehicle by a driver, the system including: a data acquisition unit that is configured to acquire traveling data including time series data of acceleration in a predetermined traveling scene; and an evaluation unit that is configured to calculate, on a basis of the traveling data, time series data of snap which is the second-order timedifferential of acceleration and evaluate driving skills in the traveling scene on a basis of time series data of snap in an evaluation target period which is a transitional period of acceleration ina recording period of the traveling data.
