The purpose of this study was to explore the efficacy of using a computer word processing program in the assessment of written expression with college-bound individuals who had been diagnosed with a learning disability (LD) and/or attention-deficit/hyperactivity disorder (ADHD). Fifty-six (35 eleventh and 21 twelfth) graders, attending a private college-preparatory school for students with LD and/or ADHD, were administered the Spontaneous Writing composite of the Test of Written Expression - Third Edition (TOWL-3). The TOWL-3 has equivalent forms, Form A and Form B. One form was administered in accordance with the test manual, using paper and pencil (standard format). The other form (i.e., alternate format) was administered with word processing access. Paired samples tests (repeated measure) and bivariate correlation designs were computed to explore the relationships between measures. Results of the study revealed significant increases (p<.01) in the subtest and composite scores when participants were administered the test in the alternate format. Other components of the research study did not reveal strong meaningful relationships when cognitive ability, graphomotor speed, and keyboarding rate were compared with the standard and/or alternative formats of the writing composite. A high rate of comorbity was exhibited with the majority of participants (75%) having two or …
