Pros:•Portability

•The transmitter (microphone) and receiver can be brought among multiple classrooms

•Ease of Use•The student turns on the receiver, the teacher turns on the transmitter and clips it to their clothing

•Upkeep•Rechargeable batteries- plug in the unit nightly to recharge!

•Benefits for other students•There has been some evidence to indicate personal amplification systems benefit children with learning disabilities. (Source)

Cons:•Upkeep

•The student and teacher need to be mindful of the power still in the system- it needs to be recharged nightly

•Easily observable by others•If a student is afraid of bullying due to FM system use, the student may be reluctant to use it. Alternatively, a student can use a non-invasive system such as a Pocketalket Ultra.
