This research analyzed the combined results of three meta-analyses which examined the extent to which a variety of measures of specific abilities related to reading. More than 450 studies were reviewed and almost 11,000 different coefficients were analyzed. The best predictors of reading proved to be other written language abilities (i.e., abilities involving print). The implications were: (1) professionals interested in improving literacy skills should focus on teaching written language abilities such as print awareness and book handling, letters, phoneme-letter correspondences, word recognition, alphabet knowledge, and comprehension and (2) the current interest in the role of nonprint abilities in reading such as phonological awareness, rapid naming, intelligence, and memory might be overemphasized.
