Vision and Hearing

Washington State law (WAC 246-760) requires schools to conduct auditory and visual screenings of children each year.  All students in grades K through 5 and 7 are screened. Students in 6th, 8th and 9th grades are screened if they meet any of the following criteria:

  • New to the CK District
  • Receiving Special Education services
  • Screening is requested by the parent or teacher

If your child is not scheduled to be screened this year you may request a screening by contacting your child's teacher or by emailing Health Services,giving your child's name, school, grade and teacher and any concerns you may have.

Vision screening is done using a Snellen E chart or standard Snellen distance acuity chart.  Students who wear corrective lenses are screened with the lenses on, and each eye is tested separately.  Visual acuity of 20/30 or better in each eye is considered passing.  Parents are informed by mail if their child does not pass the screening. 

Hearing screening is done using equipment providing tonal stimuli at 500, 1000,2000 and 4000 hertz (Hz) at hearing levels of 20 decibels (dB). Students who do not pass the hearing test are re-screened four weeks later. Parents are notified by mail if their child does not pass the second screening.

A professional evaluation by a physician is recommended for students who do not pass their vision or hearing screenings.  If you have any questions regarding the results of your child’s screening, please contact the school nurse.
