This study examines the relationship between TABE-R performance and performance on selected, more focused reading component tests after 42 hours of adult education classroom instruction. Specifically, measures of expressive vocabulary, reading fluency, sight word reading, and decoding were administered to 98 participants along with the TABE-R. This study asks, "What value is added by administering additional reading component tests?" Results indicate that when tests of fluency, sight word reading, and decoding are administered with the TABE-R, similar skill level scores are obtained for all but the decoding test.
