Engineering License from Washington to Illinois: Does It Transfer? (2026)

Last verified: 2026-07-21 · source: Illinois Department of Financial and Professional Regulation (IDFPR), Division of Professional Regulation — Board of Professional Engineers ↗

A PE license transfers from Washington to Illinois by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Illinois Department of Financial and Professional Regulation (IDFPR), Division of Professional Regulation — Board of Professional Engineers, verify your Washington license, and meet Illinois's endorsement requirements. FE and PE exam results transfer via your NCEES Record and are not retaken; Illinois requires passage of both the FE and PE exams for licensure, but an endorsement applicant whose FE was waived in another jurisdiction may submit a waiver request to the Board (68 Ill. Adm. Code 1380.280); Illinois has no separate state law exam. Note: Professional Engineer (PE) and Structural Engineer (SE) are separate Illinois licenses.

Verdict

Licensure by endorsement

Illinois grants PE licensure by comity, so a Professional Engineer licensed in Washington does not start over — but does file a full Illinois application. Your Washington license, ABET degree, qualifying experience, and FE and PE results reach the Illinois Department of Financial and Professional Regulation (IDFPR), Division of Professional Regulation — Board of Professional Engineers through your NCEES Record; the board's task is to confirm they meet Illinois's practice act, not to re-test you. FE and PE exam results transfer via your NCEES Record and are not retaken; Illinois requires passage of both the FE and PE exams for licensure, but an endorsement applicant whose FE was waived in another jurisdiction may submit a waiver request to the Board (68 Ill. Adm. Code 1380.280); Illinois has no separate state law exam. Note: Professional Engineer (PE) and Structural Engineer (SE) are separate Illinois licenses. Two things govern your timeline: keeping your Washington license active and unencumbered while the Illinois application is pending, and clearing any Illinois-specific exam or statutes review before the license issues.
