PROBLEM TO BE SOLVED: To easily evaluate the possibility of developmental disability for a large number of subjects. A developmental disability possibility evaluation device for evaluating the possibility of developmental disability evaluates each test data of ASSQ test, ADHD-RS test, DCDQ test, SDQ-T test, and PSI-C test, respectively. , The test data evaluation unit 120 that obtains the evaluation result of each test data that is an index for obtaining the result of each test, and the developmental disorder that obtains an index indicating the possibility of developmental disorder based on the evaluation result of each of the above test data. It has a possibility evaluation unit 130.
