A longitudinal study was designed to investigate the possibility of improving current accuracy in prediction of reading disability, using phonological awareness (PA), oral language, and auditory temporal processing (ATP) as predictors. Preschoolers (n = 106) were tested on PA, and two groups were selected from the upper and lower quartiles of the PA distribution for initial testing as prereaders on ATP and oral language, and later testing on reading and oral language at the end of years 1, 2 , and 3. Oral language markedly improved levels of prediction previously achieved using PA alone. However, although ATP is related to PA and oral language in prereaders, it contributed little to prediction of reading achievement beyond that afforded by measures of PA and oral language. Options for improving the levels of prediction achieved here by increasing the sensitivity of our measure of AJP are discussed.
