A study examined the effectiveness of the Reading Recovery program in the Irving, Texas, Independent School District. Subjects were students discontinued from the Reading Recovery program because they scored at or above the 40th national percentile, selected students from Chapter/Title I programs on campuses that did not implement Reading Recovery, and randomly selected students from the same grade level cohort. Subjects' scores on the reading comprehension subtest of the Iowa Tests of Basic skills were compared. Results indicated that (1) Reading Recovery students showed a potential to achieve the objective of the 50th national percentile; (2) Reading Recovery students tended to score higher than Chapter/Title I students but lower than non-Chapter I students; (3) a majority of the discontinued students avoided referral to additional remedial programs; and (4) Reading Recovery students tended to maintain gains in reading comprehension across the years. Findings support the continuation of Reading Recovery as an effective early-intervention strategy for improving reading performance of at-risk students. (Contains 4 tables and 9 figures of data.) (RS)
