The OT Assessment Package (OTAP software) is used to implement many-facet Rasch analyses that convert a student’s raw item scores for at least two schoolwork tasks into linear school motor and school process quality of performance measures. These School AMPS measures are adjusted to account for the challenge of the tasks and the severity of the rater who scored the student’s schoolwork task performances. This process enables evaluations based on the performance of different tasks and/or scored by other School AMPS raters to be equated. The resulting School AMPS measures are quantitative representations of a student’s overall ability to perform schoolwork tasks, reflecting the level of clumsiness or physical effort, efficiency, safety, and independence the student demonstrated while performing schoolwork tasks. One school motor and one school process measure is generated by the OTAP software and those measures are based on an analysis of all schoolwork tasks the student performed. A minimum of two schoolwork tasks is required to obtain school motor and school process measures that are valid and reliable.
The occupational therapist can use the OTAP software to generate several reports that assist with analysis of a student’s quality of schoolwork task performance, documentation of the results of the School AMPS observation, intervention planning, and interpreting the significance of a change in quality of schoolwork task performance upon re-evaluation.
