Effects of preschool phoneme identity training after six years: Outcome level distinguished from rate of response.

Grade 5 children who had been trained in phoneme identity 6 years earlier in preschool were superior to untrained controls on irregular word reading; on a composite list of nonwords, regular words, and irregular words; and on a separate nonword test. Some of the trained children had become poor readers by Grade 5. These poor readers had made slow progress in achieving phonemic awareness in preschool even though they were eventually successful. In general, the rate at which trained children achieved phonemic awareness in preschool accounted for variance in school literacy progress in addition to that accounted for by the actual level of phonemic awareness achieved. Preschool instruction in phonemic structure had modest but detectable effects on later reading skill, but children who were slow to achieve phonemic awareness tended to be hampered in later reading growth.
