The chapter demonstrated how we could evaluate the advantages and disadvantages of each assessment method from a measurement perspective, given an assessment design or selection context.
Our choice of assessment method should be guided by the assessment purposes, the targeted population, and the substantive nature of the construct to be assessed. The chapter recommended that both developers and users evaluate the pros and cons of employing one assessment method over another, or of combining more than one assessment method, in particular testing situations. Such decisions would affect the validity, reliability and utility of an assessment and its application. Justification of the assessment method during assessment design is detailed in later chapters as a part of the process model for assessment design/selection, validation, and use.
