CHAPTER 3. Estimating Item Parameters CHAPTER 3: Estimating Item Parameters 47. CHAPTER 3. Estimating Item Parameters Because the actual values of the Parameters of the items in a test are unknown, one of the tasks performed when a test is analyzed under item response theory is to estimate these Parameters . The obtained item parameter estimates then provide information as to the technical properties of the test items. To keep matters simple in the following presentation, the Parameters of a single item will be estimated under the assumption that the examinees' ability scores are known.
