I'm surprised it gave you that much of a breakdown of the results! I was assuming it would just be a pass/fail score.
I agree about the ITE course. It felt very incomplete to me after taking the exam. I'm super raw on traffic related stuff and my company is just starting to break into traffic studies and things of that nature, so my resources are little to none. I've done lots of traffic signal, lighting, signage, and pavement marking type design, but very little "Traffic Engineering". We had our only PTOE leave recently(which meant we lost some prequalifications with the Indiana Department of Transporation) so I decided to take on a new challenge by going after my PTOE and breaking into a new field. So I really have gone out on a limb. Hopefully I'm not one of the 17 who didn't pass, but unfortunately it wouldn't be surprising to me just due to my unfamiliarity with many items tested.
