Kansas public schools are responsible for thorough vision screenings of students but are not responsible for exams by a physician.
Vision exams are the responsibility of the student’s parent or guardian. The Kansas State Board of Examiners in Optometry has more information here.
Missouri public schools require students entering first grade to have a vision exam, “Every Child enrolling in kindergarten or first grade (for those school districts without a kindergarten) in a public elementary school in Missouri is required to receive one comprehensive vision examination.” Read about the Missouri Children’s Vision Law on the Missouri Department of Social Services website.
