Immunizations

Oregon law requires students to maintain certain levels of immunizations throughout their K-12 experience. Parents must present proof of immunizations when a child enrolls in school. We require immunizations prior to entering preschool, kindergarten, grades 1-6, and grades 8-12, with updates before grade 7. If students do not have proof of immunization by a certain date each year, the school could exclude them from the classroom until the vaccines are brought up to date.
