Is this technology really needed? The answer is sometimes yes, if the technology is assistive technology. Assistive technology (AT) is essentially any device that is needed by an individual with a disability to increase, maintain, or improve functional skills. Assistive technology helps individuals complete activities of daily living, communicate, use a computer, read, write, organize, complete math, hear, see, control their environment, and move around. For students who require AT to achieve in school, it is not just a 'neat tool' for them to use but also essential for success.
