our latest endorsement


Throughout the 10 years we have been working with them, CommPro Inc. has always provided prompt, reliable, and professional service, even when we submit a last-minute request.  College students with hearing impairments must be competitive with their hearing classmates.  CommPro’s services continue to help UA students with hearing impairments to participate and compete real-time in classroom activities – something printed notes alone just can’t do.

Note: Tests were given on three separate units. A total of 27 were possible for each test.

Means are adjusted for pretest vocabulary and prior knowledge.
