Most anti mandatory license posts that come from US engineers revolve on two main themes.
I know some idiots who are licensed.
Or
My industry does not require licensing so why should I get it?
As to the first, yes there are some idiots with engineering licenses out there. There are also some idiots with driver’s licenses out there but that does not stop anyone from driving. Just because the process allowed someone who you feel is un-qualified to become an engineer, why should that stop you from proving that you are at least as qualified as they are.
If your industry does not require licensing, then why not? What is it about some industries that make them less of a risk to public health and safety than others? A badly designed baby carriage can kill just as a badly designed building can collapse and kill someone.
Some industries have qualifications that are said to be harder to get than a PE and more relevant to being an engineer in that industry than the PE process. My response to that is why not make that qualification (plus academic and experience requirements) a sufficient condition to becoming a PE?
This does not mean that the US path to becoming licensed is a good one and cannot be improved. Under the US system, performance on two one day exams, one of which is open book and both are multiple guess format, is the main gateway to entry to the profession.
Exams are a bad gateway for two reasons. Firstly it is impossible to simulate the range of actual practices and procedures that exist in a real professional engineering job. The questions that I have seen are of the type of how much water will flow in this pipe. The real question is to first determine how much water you need to be able to drain, examine the use and application and then pick the material and size and slope necessary to do this with full regard for safety, economy and durability.
Secondly the exams have trouble keeping current with the vast range of engineering. The electrical exams have been said to be mostly generation and power transmission related. This does not adequately test the knowledge of someone who is an electronic designer.
I am Canadian. We have mandatory licensing. If you are not a P.Eng than you cannot legally call yourself an engineer nor can you practice engineering. There is no industrial exemption.
In the US any idiot can call himself an engineer. Anyone wonder why the profession is not as highly thought of in the US as is the case elsewhere?
