Education
Candidates for Federal Government professional engineering positions must meet certain basic professional knowledge requirements. Generally these knowledge requirements are met by having a bachelor's or higher degree in a relevant professional engineering discipline (e.g., mechanical, metallurgical, materials, nuclear, structural, chemical, electrical) from a school of engineering with at least one professional engineering curriculum accredited by the Accreditation Board for Engineering and Technology (ABET).
However, if you do not possess such a professional engineering degree, you may still satisfy the professional knowledge requirements if you have current Professional Engineer (P.E.) registration in one of the relevant disciplines from any U.S. State or Territory; or if you successfully passed an Engineer-in-Training (EIT) written examination administered by a State Board of Engineering Examiners; or if you have either a related professional degree or at least 60 semester hours of specified engineering-related college courses COMBINED WITH at least a year of professional engineering work experience performed under professional engineer supervision and guidance.
Note: Engineering technology degrees are not generally qualifying unless supplemented by other evidence of the individual's professional knowledge (e.g., current P.E. license or EIT examination results, as discussed above).
More detailed information about these alternatives for meeting the knowledge requirements for Federal professional engineering jobs are described in the U.S. Office of Personnel Management Qualification Standards Operating Manual which may be accessed at the following Web site:
You must include an unofficial or official copy of your college and/or university transcripts with your application. Transcript must include the School Name, Student Name, Degree and Date Awarded (if applicable). Education must be from an accredited (or pre-accredited) college or university recognized by the U.S. Department of Education. If you have multiple degrees (e.g., BS, MS, PhD) please submit transcripts for each degree.
FOREIGN EDUCATION: Education completed in foreign colleges or universities may be used to meet the requirements. You must show proof the education credentials have been deemed to be at least equivalent to that gained in a conventional U.S. education program. It is your responsibility to provide such evidence when applying. For special instructions pertaining to foreign education and a list of organizations that can evaluate foreign education, see the Department of Education website. If you are qualifying on foreign education, you MUST submit proof of creditability of education as evaluated by a credentialing agency. Transcripts must be uploaded with your application to verify education. All documentation must be in English or include an English translation.
