-------In your unit readings, you read about two approaches or models of validity—trinitarian and unitary. In some ways, these two models are competing views of gathering evidence for a test's validity. In other ways, the two approaches have an overlap of elements.
------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.
