A personality testing apparatus which tests the personality of a subject has a display means (1) which displays question items (10) of MMPI (Minnesota Multiphasic Personality Inventory) to the subject, an input means (2) for inputting answers of the subject to the question items (10), a storage means (31) which stores test data obtained from the answers of the subject, a data processing means (3) which reads the test data, calculates the test data according to each criterion and generates a result table (20) obtained by aggregating the calculation result. The apparatus enables the subject to easily answer to MMPI, and makes it possible to accurately and speedily score and aggregate the test data.
