MAT Service Delivery for Assistive Technology Practice Test

Power availability is a gating constraint in AT selection because devices need power to operate, be charged, and be used reliably throughout the day. If there aren’t convenient outlets or stable charging options, the feasibility of using a particular device drops, making power access a primary factor in deciding what AT to choose. Lighting and acoustics influence usability—such as screen readability or how well a device’s audio features work—but they don’t determine the core viability of the device in the same explicit way. Furniture color, meanwhile, generally has no impact on device function or usability.
