ABSTRACT
Since the publication of the first edition of this book (Wainer et al., 1990), we have learned a great deal about CAT operational problems that perhaps ought to have been obvious, and hence discussed, but alas, were not. Our previous lack of attention to operational issues was a grievous oversight. This chapter is meant to ameliorate that deficiency. In it we focus on three separate, but fundamentally related, issues: examinee access, item pool usage and security, and the economic realities of CAT. This focus is quite different from that taken in the first nine chapters of this book, which are principally concerned with psychometric issues.
