Assistive Technology Continuum

Assistive technology exists on a continuum and can range from low tech to high tech.  When considering technology, you should first start with low-tech and then progress to mid-tech or high-tech if you still haven't met the student's needs.  Assistive technology does not have set rules in which certain devices work for certain people.  It depends on the individual person and their individual needs. What device is appropriate for one person, may not be appropriate for another.  You can find the most beneficial device through careful evaluation and by actually using it and trying it out.
