Wright (1977) shows that a debate is developing between those who strongly advocate use of the Rasch model and those who have certain reservations about the extent to which the model meets some traditional concerns in trait measurement. In an earlier article, Whitely and Dawis (1974) presented the Rasch model in the context of least squares estimation, and noted some features that may limit the utility of the model in test development. Wright (1977) questions several of the specific interpretations and conclusions that were given in the earlier article. The current article is a response to those questions.
