This paper presents a preliminary model for a table of specifications for Language Curricula Development Center Language Arts materials. Description of the development of the Criterion-Referenced Unit Achievement Tests, including the tests' design, precedes the recommended model. The model categorizes the main components and behaviors of the SCDC Structud Reading Series, demonstrating how test items are developed keyed to each level of Bloom's Taxonomy. This type of test item costruction has been basically followed in developing SCDC tests. The Language Arts Vernacula Strand follows an eclectic approach in reading instruction. At the Primary One Level, it offers a dual purpose Spanish Vernacular reading program: structured reading and related skills of comprehension and interpretation, and language experience reading with oral language development. At the Primary Two Level, it is broadened by a Language Analysis component and by adding creative expression dimensions to the language experience and oral development skills. (Author/CLK)
