I love the progression of the discussion through various graphs. This helps walk readers/students through the rationale behind Rasch, whereas so many other texts just present the various curves and estimates/equations as independent concepts to learn.
Students can really develop a critical insight of all the phases of the test development procedures. The book provides clear information for students to understand what they need to consider when developing an instrument as well as what to look for when choosing an instrument to integrate in practice.
Nicely written and includes many tacit aspects of assessment that will be helpful to students. It is clear from the writing that the author has extensive experience in the field.
Because I hold some additional roles outside instructional duties, I requested this text to gain stronger insight on the "fairness" of the standardized exam process, generally for reporting, following additional research, to the appropriate administrators and admissions department. However, as I reviewed, I discovered little that I did not know or of which I possessed at least basic knowledge. Found it lacked sufficient probative value.
