🏠 Homeschool Information
Requirements
Montana does not require immunization for homeschool students. Under Montana Code Annotated §20-5-403, immunization requirements apply to students 'enrolled in a school,' but Montana homeschool statute §20-5-109(4) explicitly exempts homeschool students from the immunization mandate.
Reporting
No immunization reporting required for homeschool students.
Exemptions
Not applicable — homeschool students are explicitly exempted by statute. Montana allows medical and religious exemptions for school-attending students.
Notes
Montana is one of the few states where the exemption is explicit in the statutory text rather than being a matter of interpretation. MCA §20-5-109(4): 'The immunization requirements...do not apply to a child who is being homeschooled.'
