A hearing evaluation may consist of pure-tone thresholds or otoacoustic emissions (OAE).
After a failed screening by the school nurse, if a referral for audiology is warranted, Tri-County Special Education will processes a referral from the member district nurse to our contractual audiologist. A request for this testing requires parent and administrative consent, includes the failed screening documentation along with the treating physicians report provided to parents by the school nurse, and may or may not be part of a special education needs assessment referral.

Hearing Referral & Consent Form


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. This is different from language processing or the skills of attention and concentration.  Valid and reliable testing for possible APD requires that a child be at least 7-8 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.
Through a school’s multi-tiered systems of support, concerns regarding the processing of auditory information to the brain may include a review of the listening and learning abilities and behaviors in the classroom and specific screening measures. There is a variety of screening measures and tools used by speech-pathologists to determine whether further auditory testing may be warranted. These include, but are not limited to, Test for Auditory Processing Disorders in Children (SCAN-C), Differential Screening Test for Processing (DTSP), Fishers Checklist, and the Children’s Auditory Processing Scale( CHAPs). None of these measures are used to diagnose auditory processing disorders. These screening measures allow the educational team to have information regarding these skills PRIOR to a referral if further testing is suggested by the results.  Only a qualified audiologist can diagnosis auditory disorders after they complete a full battery of tests in a soundproof booth and review the additional language, cognitive, academic and health-related testing completed by the school district.  This full assessment of educational strengths and weaknesses allows the audiologist and team to rule out co-existing conditions that may appear to be auditory in nature. Consent for this in-depth testing, conducted by an audiologist, is part of a full case-study evaluation AND requires parent consent through an  Individual Needs Assessment /Review of Existing Data (INA) meeting.
