Our courses & exams are based on the NCEES Continuing Professional Competency Guidelines, which is the guide used by most states for their continuing education requirements. Our state coverage map can be viewed at the top of the page. We make every effort to stay current with the engineering licensing boards for each state, including Iowa. However, with always changing rules by the state boards, we cannot guarantee that all information here is always accurate & up to date. We encourage you to use this page as a summary of some of the key points for each state's P.E. licensing requirements only and be sure to frequently fully review your board's current PDH rules.
