The Decoding Skills Test (DST) was developed to provide a detailed measurement of decoding skills which could be used in research on developmental dyslexia. Another purpose of the test is to provide a diagnostic-prescriptive instrument to be used in the evaluation of, and program planning for, children needing remedial reading. The test is criterion referenced, and consists of three subtests: Basal Word Recognition--11 lists of 10 words each (Subtest I); Phonic Decoding--lists of real/nonsense words (Subtest II); and Oral Passage Reading--11 passages corresponding to Subtest I (Subtest III). Although it does not emphasize comprehension ability, a "simple recall" comprehension supplement is included for detection of gross comprehension deficiencies. The manual explains test instructions, administration, and scoring procedures. Diagnostic scoring information and current uses of the DST for research and evaluation are also included; a copy of the DST is appended. (GK)
