Illinois PE license requirements

In Illinois you don’t need approval to take the PE: register with NCEES at any time. You then apply for licensure to the Illinois Department of Financial and Professional Regulation (IDFPR) with four years of professional, non-structural engineering experience and an NCEES Record. Illinois licenses structural engineers separately, and since April 2024 it no longer accepts the NCEES PE Civil: Structural exam toward the PE license.
