The paper
Wisconsin accepts a statement written at home. Fill in the blanks, print it, sign it.
Wis. Stat. 252.04(3) names those three reasons. Keep the one that is true and strike the others. The Student Immunization Record, form F-04020L, has a box for each and may be used instead.
The paper. Student Immunization Record, Department of Health Services form F-04020L, personal conviction waiver box, or the parent's own written statement. There is no state form to fill in. How long it lasts: None stated in the law or on the form; a vaccine or dose required after enrollment needs its own new waiver.
This is a summary of public law, not legal advice. Requirements change, so always confirm with your state before you file.
