Delaware sits between Philadelphia, Baltimore, and the DC metro — which means transfers from neighboring states are especially common. Here's what Delaware requires for school enrollment, how to get records through DELPHI, and how to handle the transition whether you're moving to the Red Clay, Christina, or Capital school district.

14 Del. C. §131 and 16 Del. Admin. Code §4202 require proof of immunization for school entry. Your child's new Delaware school will ask for a certificate of immunization showing dated dose records for DTaP, IPV, MMR, Hepatitis B, Varicella, and Hepatitis A (kindergarten) — plus Tdap and MenACWY at 7th grade.
Delaware has only three counties — New Castle (Wilmington, Newark), Kent (Dover), and Sussex (Rehoboth, Georgetown). All follow the same state immunization requirements. District-level enrollment processes vary, but the vaccine documentation is identical statewide.

Your new Delaware school will request cumulative records from your child's former district. Delaware law requires schools to maintain and share student records upon transfer request. Processing varies — typically 2–4 weeks from out of state. Bring your own copies to the enrollment appointment to avoid waiting on the mail.
Once you have a new Delaware provider, they can enter out-of-state doses into DELPHI — the Delaware Immunization System. Contact your child's former pediatrician for a signed immunization summary first — this is the fastest path.
If your family used providers in neighboring states (PA, MD, NJ), those doses may already be in the sending state's registry. Request a printout and bring it to your new Delaware provider for verification and entry into DELPHI.

Delaware families frequently see providers across state lines — a pediatrician in Philadelphia, a specialist at Johns Hopkins in Baltimore, or a dentist in Cherry Hill. Doses administered out of state won't automatically appear in DELPHI. When establishing care with a Delaware provider, bring records from every provider, regardless of which state they're in.
When you establish care with a new Delaware pediatrician, bring:
Your new provider will enter records into DELPHI going forward. Out-of-state doses can be added retroactively with dated documentation.
Red Clay Consolidated School District — Serves much of northern New Castle County including parts of Wilmington. Enrollment is handled at individual school offices. Bring immunization documentation, proof of residence, and birth certificate.
Christina School District — Covers Newark, Bear, and parts of Wilmington. The district's Choice & Enrollment Office processes transfers. Christina follows the state's provisional enrollment rules for students with in-progress immunization series.
Capital School District — Based in Dover (Kent County). The Central Registration Office handles enrollment. Bring all health documentation to the registration appointment — Capital processes new enrollees year-round.
Request a complete medical record summary from every current provider — including any cross-state providers. Ask for a signed immunization history. If your child hasn't completed the Hepatitis A series and is approaching kindergarten age, ask your current provider to start it before the move.
Enroll at the assigned school and bring immunization records, proof of residence, and birth certificate. Ask the school to request cumulative records from the former district. Delaware allows provisional enrollment while the series is being completed on schedule.
Your new Delaware pediatrician will review existing records, enter doses into DELPHI, and provide the immunization certificate the school needs. If you plan to continue seeing providers across state lines, bring each visit's records to your Delaware provider for DELPHI entry.
