The 111 tests cited in this bibliography are used to diagnose students' reading problems so appropriate instructional and remedial strategies can be planned and implemented. Many of the tests described are included because one or more or their subtests measure some aspect of written knowledge and how students process and comprehend words and sentences. Although grades preschool through 12 are represented, the tests are primarily designed for grades preschool through 6. This document is one in a series of topical bibliographies from the Test Collection (TC) at the Educational Testing Service (ETS) containing descriptions of more than 18,000 tests and other measurement devices prepared by commercial publishers, teachers, educational institutions, professional associations, departments of education, counselors, etc. Each description contains the following basic information: TC Accession Number (a six-digit identification number assigned by the Test Collection); the title of the instrument; personal or institutional author; year of publication or copyright; availability source; grade level for which test is suitable; age level for which test is suitable; and abstract. Other information, which is provided when known, includes subtests, number of test items, and time required to complete the test.
