C) split-half method
D) internal consistency method

The test-retest method involves administering the same test to a group of individuals at two different times and correlating their scores. This method is specifically designed to measure the consistency of test scores over time, making it the best choice for this scenario. The alternate forms method involves administering two different but parallel forms of the same test to the same group of individuals, which is not happening in this scenario. The split-half method involves splitting a test into two different halves and correlating scores on each half, which is also not happening in this scenario. The internal consistency method involves examining the extent to which items on a test are interrelated, which is not being done in this scenario.
