The compound noun 'test-taking' is a modern formation that transparently combines two established English words. The first element, 'test', has a journey from Latin testum, an earthen vessel used as a witness in transactions, evolving through Old French to signify a 'trial' of one's qualities. The second element, 'taking', originates from the Old English verb for seizing or capturing. When fused, the literal sense of "seizing or undergoing a trial" logically crystallizes into the contemporary abstract meaning: the specific activity or skill of participating in an examination. This compound exemplifies how English readily creates precise terms for modern concepts by joining familiar morphemes.
