<p>What is this thing about becoming a Professional Engineer? I read that all engineers that "directly serve in public" or something along those lines, all need a license, that's given by the state. How does this work and what is it necessary for? thanks in advance</p>
<p>All US states have post-graduation examination and licensing programs for Professional Engineers, just as they do for accountants, lawyers, doctors, architects, surveyors, and other professionals. The difference is that most engineers are legally exempt from licensure. Only about 20% of practicing engineers actually become licensed.</p>
<p>In practice, you typically need a PE license to design customized structures, roads, or utilities that will become part of the nation's permanent infrastructure. You typically don't need a PE license to design mass-produced portable products that could be used anywhere. Examples: </p>
<ul>
<li><p>You probably don't need a PE license to design a bulldozer. But you probably do need a license to prepare a grading plan that will change the local landscape.</p></li>
<li><p>You probably don't need a PE license to design a server. But you probably do need a license to design the power or HVAC systems for a server farm. </p></li>
<li><p>You probably don't need a PE license to design a car or an airplane. But you probably do need a license to design a highway or an airport.</p></li>
</ul>
<p>A PE license is typically required for CEs (including structural, geotechnical, traffic, etc), some EEs (power engineers), and some MEs (HVAC engineers). You may also need a PE license to provide consulting services or expert witness testimony, or to use certain engineering titles. </p>
<p>The licensing process typically involves two 8-hour exams. The FE exam is usually taken by college seniors; the PE exam is usually taken after a few years of qualifying professional experience. The PE exam (like the Bar or CPA exams) is generally considered challenging.</p>
<p>I thought I'd chime in that I agree with Corbett--good explaination!</p>
<p>Also, most engineers won't get their PE license unless they are the head engineer on the job...and then the blame, etc, falls on them!</p>
