Conducting 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 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

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?

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

Completing the Assistive Technology Assessment Checklist

• How will the individual access printed information?– Regular Print– Large Print– Use Optical Devices– Non-optical Devices– Braille & Tactile– Auditory– Reading Rates– Electronic Calculator and Dictionaries

How will the individual access printed information?


• Regular Print– Can the individual read regular print

without modification or an optical device?• At what distance• Which fonts• Is this effective and efficient?

– Can the individual read regular print with standard spectacles or contact lens?

• At what distance• Which fonts• Is this effective and efficient?


How will the individual access printed information?• Enlarged Print

– Can the individual read enlarged print without modification or an optical device?

• At what distance• What % of enlargement is needed?• Is this effective and efficient?

– Can the individual read enlarged print with standard spectacles or contact lens?

• At what distance• What % of enlargement is needed?• Is this effective and efficient?

– Does the reduced clarity cause problems?



• Large Print– What point size at what distance?

• Various sizes for reading• One size for writing

– What’s the preferred font?



• Optical Devices– Has individual received a Clinical Low Vision

Evaluation?– What was recommended? Need for multiple

tools• Manual tools• Electronic tools• Tools for spot reading• Tools for continuous reading• Tools for distance reading tasks

– How well does the individual use the devices?
