Engineering License from Pennsylvania to Delaware: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: Delaware Association of Professional Engineers (DAPE) ↗
A PE license transfers from Pennsylvania to Delaware by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Delaware Association of Professional Engineers (DAPE), verify your Pennsylvania license, and meet Delaware's endorsement requirements. FE and PE exam results transfer through your NCEES Record and are not retaken; Delaware requires no separate proctored jurisprudence exam, but comity applicants must complete an Ethics & Regulations questionnaire.

Verdict
Licensure by endorsement
Delaware grants PE licensure by comity, so a Professional Engineer licensed in Pennsylvania does not start over — but does file a full Delaware application. Your Pennsylvania license, ABET degree, qualifying experience, and FE and PE results reach the Delaware Association of Professional Engineers (DAPE) through your NCEES Record; the board's task is to confirm they meet Delaware's practice act, not to re-test you. FE and PE exam results transfer through your NCEES Record and are not retaken; Delaware requires no separate proctored jurisprudence exam, but comity applicants must complete an Ethics & Regulations questionnaire. Two things govern your timeline: keeping your Pennsylvania license active and unencumbered while the Delaware application is pending, and clearing any Delaware-specific exam or statutes review before the license issues.
