Quizplus · Accepted Answer

Test-retest reliability assumes that the characteristic or trait being measured is stable over time and that there are no significant changes in the test conditions or participants' knowledge that could affect their performance on the retest. It does not assume that it is only valid for measuring situational traits; rather, it is applicable to a wide range of stable traits and characteristics.
