C. Personality tests are designed to measure enduring traits, characteristics, and behaviors that define an individual's unique way of interacting with the world. This matches I. Measures the traits, qualities, or behaviors that determine a person's individuality.
D. Achievement tests measure what a person has already learned or accomplished in a specific domain, such as mathematics or reading. This matches II. Measures a person's degree of learning, success or accomplishment in a subject or task.
Therefore, the correct pairings are A-III, B-IV, C-I, and D-II.
Step 3: Final Answer:
