(d) Referral. The schools shall provide the parents or guardians of children who fail the hearing tests with a written notification of the test results and recommend that a medical and audiological evaluation be obtained whenever the test demonstrates:

• (1) A hearing level of 30 decibels or greater for two or more frequencies in an ear at 500, 1000, 2000 or 4000 Hertz, or a hearing level of 40 decibels or greater for one of the frequencies tested, 500 through 4000 Hertz, on two threshold tests completed at an interval of at least two weeks; or
• (2) There is evidence of pathology, such as an infection of the outer ear, chronic drainage, or a chronic earache.

The California State University shall notify the parent or guardian of each pupil for whom the assessment has detected health problems and shall recommend further consultation with a physician. If there is no physician available, the coordinating center shall direct the parent or guardian to an appropriate medical referral.
