This publication lists and describes diagnostic reading tests available from United States publishers. Critical reviews by outside experts are included and supplemented by the compiler's comments. The external reviews are abstracted from "The Mental Measurements Yearbooks," edited by O. K. Buros, and cited by Yearbook edition and entry number. The introductory material serves two purposes: (1) to outline some considerations to be followed in selecting diagnostic tests and (2) to provide background for the understanding of technical information provided in test manuals and reviews.
