Qualifications Definitions: EXPERIENCE: One year of work experience is twelve months working full-time (at least 35-40 hours per week). Part-time experience can be pro-rated (i.e., a year at 20 hours per week is credited as 6 months of experience). If your position consisted of mixed duties, experience credit is given for the percentage of time that you spent on qualifying duties (i.e., if you held a position for 2 years, full-time, consisting of 25% personnel work and 75% budget work, and then applied for a budget position you could calculate your experience as follows: 2 yrs = 24 months. 24 months x 75% [percentage of time spent on budget duties] = 18 months of qualifying experience.) UNDERGRADUATE EDUCATION: A year of undergraduate education is 30 semester hours, 45 quarter hours or the equivalent of college study. This education must have been obtained in an accredited college or university for which high school graduation or the equivalent was a prerequisite. GRADUATE EDUCATION: In the absence of specific graduate program information, a year of graduate education is 18 semester hours or 27 quarter hours of graduate level college course work, or the number of credit hours the school attended has determined to represent 1 year of full time study. This education must have been obtained in an accredited college or university. BASIC REQUIREMENTS: A. Degree in Engineering. To be acceptable, the program must: (1) lead to a bachelor's degree in a school of engineering with at least one program accredited by ABET; or (2) include differential and integral calculus and courses (more advanced than first-year physics and chemistry) in five of the following seven areas of engineering science or physics: (a) statics, dynamics; (b) strength of materials (stress-strain relationships); (c) fluid mechanics, hydraulics; (d) thermodynamics; (e) electrical fields and circuits; (f) nature and properties of materials (relating particle and aggregate structure to properties); and (g) any other comparable area of fundamental engineering science or physics, such as optics, heat transfer, soil mechanics, or electronics. **OR B. Combination of education and experience -- college-level education, training, and/or technical experience that furnished (1) a thorough knowledge of the physical and mathematical sciences underlying engineering, and (2) a good understanding, both theoretical and practical, of the engineering sciences and techniques and their applications to one of the branches of engineering.
