The purpose of this study was to compare the effects of word list order (length, alphabetic, and frequency of word use) on the rate with which two groups of students identified targeted words from word prompt lists. The two groups were composed of participants with language and learning disabilities and participants with age-appropriate language and literacy skills. Results indicated that both groups identified targeted words more rapidly when words were ordered by length rather than by alphabet or frequency of use.
