A hearing evaluation may consist of pure-tone thresholds or otoacoustic emissions (OAE).
After a failed screening, if a referral is warranted, Tri-County Special Education processes these referrals from its member districts nurses to the designated contractual audiologists. A request for this testing requires parent and administrative consent and may or may not be part of a special education referral.  Hearing Referral & Consent Form



Through the APD Screening process, a child may be referred to an audiologist, for a Central Auditory Processing (CAP) evaluation by his/her educational team and in agreement with the parents as part of a multidisciplinary review of the listening and learning abilities and behaviors in the classroom.

There are a variety of screening measures and tools used to determine if further testing is needed.
A request for this in-depth testing, conducted by an audiologist, is part of a full case-study evaluation, not an isolated test  AND requires parent consent through an  Individual Needs Assessment / Domains Meeting(INA).

Auditory processing is what our brain does with what it hears. This is a central nervous system issue related to how the brain translates signals and sounds that are heard. Most of the tests of APD require that a child be at least 8 years of age because the variability in brain function is so marked in younger children that test interpretation may not be possible. Although the human auditory system is fully developed at birth, auditory pathways don’t mature until age 10-12 years old.

The child must be 8 years or older
The child must have cognitive functioning in the average range
The child must be proficient in English
The child must have normal hearing
