I tend to disagree a little. I worked for a "Lenel Certified Company" which was actually owned by UTC, and I feel like there were some non Lenel Certified companies in our area that did it much better than we did. The training was sub-par, the best part of it to me was just getting to play around with the software, and I felt like after I worked on Lenel a bit, I was answering my own questions when I called into Lenel Tech Support.
Lenel is not that tricky of a system to learn, the training can help to give you the basics. Really I felt the only upside to being "Certified" is at least tech support would talk to me when I called in, not that they were always of much help.
I think it just comes down to experience with the product, plus the certification. In my limited experience it seemed like Lenel would hand out training to anyone, and then companies tout their "Lenel Certification" while installing maybe one system a year.
I will add that I had petitioned to my employer to send me for more training, but they were cheap and felt like the first week long introductory course was sufficient. Perhaps if I had been granted the additional training I would have felt it was more worthwhile.
