Presentation OutlineConducting an Assistive Technology
Assessment– Preparing for the Assessment– Completing the AT Considerations Checklist– Completing the AT Assessment form– Completing the Recommendations form– Writing the Final Report– Presenting the Assessment Report and
Recommendations
Conducting an Assistive Technology Assessment
• Preparing for the Assessment– Selecting the AT assessment team– Gathering Background Information
• Ophthalmologic Exam• Clinical Low Vision Evaluation• Functional Low Vision Evaluation• Vocational Evaluation• Learning Media Assessment• Psychological Evaluation• Academic and Other Assessments
Completing the AT Considerations Checklist
• Identify tasks the student is having difficulty completing?
• What modifications and adaptations have been implemented?
• Are these working?• What assistive technology has been
implemented? – www.gpat.org/resources.aspx?PageReq=GPATConsider#doc
What is the Assistive Technology Assessment Form?
• A guide for service provider wishing to determine technology needs
• Looking for three types of information– Does individual have sensory skills needed
• Visual, tactile, auditory– Does individual have physical skills needed– Does individual have cognitive skills needed
• A checklist of items and tasks• A checklist for recommendations

Completing the Assistive Technology Assessment
• May require multiple team members to complete
• Not all items will be applicable• Materials in alternate formats will need
to be prepared• Team members will need to gather
adaptive equipment and become familiar with its operation
• Multiple sessions may be required
Completing the Assistive Technology Assessment Checklist
