Engineering License from Illinois to Indiana: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: Indiana State Board of Registration for Professional Engineers (Indiana Professional Licensing Agency, PLA) ↗
A PE license transfers from Illinois to Indiana by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Indiana State Board of Registration for Professional Engineers (Indiana Professional Licensing Agency, PLA), verify your Illinois license, and meet Indiana's endorsement requirements. FE (Part I) and PE (Part II, the NCEES PE exam) results transfer via your NCEES Record and are not retaken (the FE is waived if already passed elsewhere); HOWEVER Indiana requires every comity applicant to complete Part III of the Indiana PE examination — a take-home (open-book) exam on professional conduct and Indiana registration law, submitted with the application.

Verdict
Licensure by endorsement
Indiana grants PE licensure by comity, so a Professional Engineer licensed in Illinois does not start over — but does file a full Indiana application. Your Illinois license, ABET degree, qualifying experience, and FE and PE results reach the Indiana State Board of Registration for Professional Engineers (Indiana Professional Licensing Agency, PLA) through your NCEES Record; the board's task is to confirm they meet Indiana's practice act, not to re-test you. FE (Part I) and PE (Part II, the NCEES PE exam) results transfer via your NCEES Record and are not retaken (the FE is waived if already passed elsewhere); HOWEVER Indiana requires every comity applicant to complete Part III of the Indiana PE examination — a take-home (open-book) exam on professional conduct and Indiana registration law, submitted with the application. Two things govern your timeline: keeping your Illinois license active and unencumbered while the Indiana application is pending, and clearing any Indiana-specific exam or statutes review before the license issues.
