Engineers have to graduate from an ABET accredited Engineering scool, pass two 8-hour exams and have 5 years of progressive engineering experience after the first test to become "Professional" (PE's).
Planners have to have the following Level of Education to sit for a test, and be a member of APA:
Total Number of Years of Professional Planning Experience Required
Accredited graduate degree in planning** 2
Accredited bachelors degree in planning** 3
Non-accredited graduate degree in planning 3
Any other post-graduate, graduate, or undergraduate degree*** 4
No college degree 8
There are codes of ethics for both professions.
The AICP test seems to reflect that "anyone" can become AICP certified, given the work experience. Doesn't this de-value the certification by not requiring the "formal" planning education? or by permitting non-planner degrees, does this certification de-value the planning degrees? Why do AICP planners not have a "stamp" similar to engineers or architects to certify site plans or studies? Just curious as to your thoughts. I have always thought of them (planning/engineering) as similar professions respect-wise, but the pay -for the most part - is not commensurate. Maybe I am missing something here.
