title: Modified test administration using assistive technology: preliminary psychometric findings.
abstract: This study examined the psychometric properties of test presentation and response formats that were modified to be accessible with the use of assistive technology (AT). First, the stability of psychometric properties was examined in 60 children, ages 6 to 12, with no significant physical or communicative impairments. Population-specific differences were then examined with samples that included 24 children with cerebral palsy and matched control peers. Children were administered standard and modified versions of tests. The type of AT access did not have a statistically significant effect on modified test scores. Measurement stability between the standard and modified versions of quadrant forced-choice format tests was sufficient. The findings support the potential use of AT and accessible procedures for some test instruments in the assessment of children with cerebral palsy.
