This paper describes the principles followed by the Educational Testing Service (New Jersey) in adapting, for students with various disabilities, the Scholastic Assessment Test I (SAT I), the commonly used test for college admissions that assesses verbal and mathematical reasoning. The paper notes that developers of standard tests should be informed early in the test construction process that the test will likely be adapted for use with students having disabilities. Examples are offered of ways that questions in both the math and verbal sections can be originally presented that make them easier to adapt later. Specific guidelines are offered for developing the SAT I in five formats: (1) cassette, (2) script, (3) braille, (4) regular type, and (5) large type. The paper stresses that the development of special versions of the SAT I for students with disabilities involves considerable attention to detail, an understanding of the populations being served, and ample time for preparing and fine-tuning the adapted materials. Appendices include a list of symbols and indicators in the Nemeth Code, and some examples of adaptations for both the verbal and mathematics sections. (DB)
