Such experience may be gained during periods of college or university enrollment, and shall be credited at one-half the time value of preprofessional experience gained after receipt of a baccalaureate degree. No more than one year of subprofessional experience may be counted as preprofessional experience. Such preprofessional experience may include one or more of the following:

(i) supervised engineering experience; or

(ii) supervised construction experience.

(b) Preprofessional experience is gained following receipt of a baccalaureate degree. Such preprofessional experience may include:

(i) no more than one year of subprofessional experience as defined in (a);

(ii) progressive experience on engineering projects which indicate the experience is of increasing quality and required greater responsibility;

(iii) experience not obtained in violation of the licensure act;

(iv) experience gained under the supervision of a licensed professional engineer/land surveyor or, if not, an explanation of why the experience should be considered acceptable;

(v) credible teaching experience at an advanced level, post graduate or senior graduate, in a college or university offering an engineering curriculum of four years or more that is approved by the board;

(vi) experience gained in engineering research and design projects by members of an engineering faculty, in an engineering curriculum approved by the board;

(vii) a master's degree in engineering will be credited as one year of experience;

(viii) a Ph.D. in engineering will be credited as two years of experience, but the applicant shall not count an additional one year for a master's degree, if earned. All degrees shall have been obtained from colleges or universities with board-approved programs.

(c) Professional experience is gained after initial licensure by a state, territory, or possession of the United States.

(3) Experience should be gained under the supervision of a registered professional engineer and, if not, an explanation should be made showing why the experience should be considered acceptable.

(4) Engineer applicants may be asked by the board to provide a more detailed explanation of their knowledge of fundamental principles of engineering design and the practical solution of engineering problems.
