A PE license transfers from Illinois to Washington by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Washington State Board of Registration for Professional Engineers and Land Surveyors (BRPELS), Washington State Department of Licensing, verify your Illinois license, and meet Washington's endorsement requirements. FE and PE exam results transfer through your NCEES Record (or issuing-board verification) and are not retaken; comity applicants must additionally pass the open-book Washington Engineer Law Review (minimum score 80%).

Verdict
Licensure by endorsement
Washington grants PE licensure by comity, so a Professional Engineer licensed in Illinois does not start over — but does file a full Washington application. Your Illinois license, ABET degree, qualifying experience, and FE and PE results reach the Washington State Board of Registration for Professional Engineers and Land Surveyors (BRPELS), Washington State Department of Licensing through your NCEES Record; the board's task is to confirm they meet Washington's practice act, not to re-test you. FE and PE exam results transfer through your NCEES Record (or issuing-board verification) and are not retaken; comity applicants must additionally pass the open-book Washington Engineer Law Review (minimum score 80%). Two things govern your timeline: keeping your Illinois license active and unencumbered while the Washington application is pending, and clearing any Washington-specific exam or statutes review before the license issues.
