Mississippi School Nurse Procedures & Standard of Care
2.4 Conducting Hearing & Vision Screening A public agency may conduct hearing and vision screening without obtaining written parental permission if there is an agency policy stating that any student who has not been successful in the regular education program may be screened for vision and hearing as a means of determining whether hearing and/or vision problems are the cause of the child's lack of success in the regular program. All hearing and vision screening must be conducted according to guidelines set forth by the Mississippi Department of Education.
