Abstract
There is provided a determination apparatus including: a result acquisition unit configured to acquire test results of tests on a plurality of items which are performed on a device under measurement; and a first determination unit configured to determine whether to retest a device under measurement that has failed the test, in which the first determination unit is configured to perform the determination based on reproducibility of the test results in a case where the tests have been performed on a plurality of devices under measurement multiple times in advance.
