——Compare and contrast these two models in terms of how they conceptualize validity.
——Identify at least one advantage and disadvantage of each model.
——Decide which model appears to be the most valid for determining validity of a test.
——-Explain your decision in terms of the implications for decision making about a test’s validity.
