According to the Assistive Technology Act, assistive devices are defined as:

The definition provided by the Assistive Technology Act for assistive devices encompasses a broad range of tools specifically designed to aid individuals with disabilities in various aspects of education and daily living. This wide-ranging definition means that assistive devices can include everything from low-tech solutions, such as pencil grips or communication boards, to high-tech devices like speech-generating software and adapted computers. The goal is to support the individual's ability to perform functions that may otherwise be challenging due to their disabilities, thereby enhancing their independence and participation in both educational settings and everyday life.

In contrast, the other options are more specific and do not capture the comprehensive nature of the definition as outlined by the law. For example, while electronic devices that support learning are indeed assistive, they do not encompass the full range of potential devices that could help a student with disabilities. Similarly, merely focusing on efficiency or experimental tools narrows the scope too much and limits understanding of the broad and inclusive intention of assistive technology. The definition must reflect the diverse needs of students with disabilities across various contexts, making the chosen answer the most accurate representation of the Assistive Technology Act.
