The 2026-27 school year for Simi Valley Unified School District begins Wednesday, August 12. Families with children entering Transitional Kindergarten should have the required enrollment materials and immunization records completed before the first day. The district lists records for polio, DPT, MMR, varicella, and hepatitis B among the required documentation, and says children may not begin school without a completed immunization record on file.
