1. Find out where you can get training for the application, including the cost.
2. Get all of your facts straight about the legality and print out the back up for your position.
3. Go to your boss and tell him about the error you found without making accusations of intentional deception, or whatever.
4. Suggest that you be put into the training program for the application as soon as possible (at the company's expense, including your pay).
5. If you boss balks, tell him you are just trying to keep him from getting in trouble with the licensing board and then start looking for a new job.
Work is tough right now and I'm sure there is a tremendous temptation to bend the rules when vying for projects. But if all you need is a training course to come up to speed, it might not be so bad. IDK, my boss sent out an SOQ a couple of weeks ago and sent an email to all employees asking if anyone had any experience on a particular type of project. As it turns out, I did, but it was 10-11 years ago. I told him what I could recall about the projects, which wasn't much, and he had marketing put that in the SOQ. Then he got a call about a week later from the potential Client wanting the exact names of the developments and other people involved. So don't let your boss think that no one will notice. In my case, I am surprised they checked. I managed to find the information they wanted using Google since I had long purged the projects from my own resume and couldn't take the time to hunt down my old timesheets in my storage locker.
