The Fairview Reading Curriculum Based Assessment (CBA), which was used in a cross categorical elementary school resource program at Fairview Elementary School in Darien, Illinois, is described. The test measures oral reading accuracy, rate and comprehension on passages taken directly from the two basal reading series used in the school. As the child reads orally, a testor records errors and uses a stopwatch to time the reading of the first 100 words of the passage. Immediately after reading, the child answers five comprehension questions for each passage. Procedures for norming the CBA are considered. Also discussed are student selection; testing; and calculation of accuracy, rate, and comprehension. Noted among findings is that improvement in reading rate will not necessarily improve comprehension. It is concluded that the CBA can be used to identify particular reading problems, for initial group placement of new students, and to identify entrance or exit criteria for resource students. Included are sample reading test passages and comprehension questions, a handout on error samples, a volunteer training session handout, and tables with statistical data. (SW)
