Under Wyo. Stat. §21-4-309, no child may be admitted to any Wyoming public or private school without proof of immunization on file. The Wyoming Department of Health maintains the Wyoming Immunization Registry (WyIR), and schools can access it directly. The Docket app is also available for parents to view their child's WyIR record on a mobile device.
Where to get your child's record: Your child's pediatrician can access the WyIR and print a current certificate. Parents can also use the Docket app to view and download WyIR records directly. Contact the Wyoming Department of Health Immunization Unit or your county public health office for record lookups.

Wyoming does not have a statewide mandate for a physical exam as a condition of public school enrollment. However, individual school districts may request a health history form or physical exam — particularly for students participating in athletics. Check with your specific district's enrollment office for local requirements.
For athletics, the Wyoming High School Activities Association (WHSAA) requires a pre-participation physical exam before students can compete in interscholastic sports. The exam must be completed by a licensed healthcare provider and is typically valid for one calendar year.

Full immunization certificate required before enrollment. Laramie County SD 1 (Cheyenne), Natrona County SD (Casper), and Campbell County SD (Gillette) all process enrollment through their central or school-level offices. Immunization records must be on file before the first day.
Tdap booster required for 7th-grade entry. Schedule with your child's provider in spring so the updated WyIR record is ready before fall registration.
Students transferring from other states must meet Wyoming's immunization requirements. Bring all prior immunization documentation to your first Wyoming provider visit for WyIR entry. Wyoming allows provisional enrollment with a written schedule for completing required immunizations — confirm your district's provisional enrollment timeline.
