The link below is to one of the various companies offering online courses to earn the credits necessary to maintain NICET certification. The great thing about Jensen Hughes is that they actually offer one basic course for FREE. You earn one credit and you get a feel for what the rest of the courses are like.

The necessity to continually earn credit hours seems like a noble cause, you want educated and skilled people designing systems that may one day save a life. But to think for the next 20, 30, 40 years you will need to find ways to earn these credits seems nearly impossible. How many different ways are there to continue to earn these credits while working in the field full time already? I believe this side of NICET Certification is very much about the money and not so much about the level of expertise.

Now, I don't want to sound like I am whining when it comes to earning the extra 18 hours needed if you've actively worked full time for the 3 year certification period, but unfortunately the company I work for has lost its most experienced designers to other companies... So I no longer have the group of professionals just across the hall to seek advice from. And, as stated in my first post, I'm not finding any easy answers online.

Check out the course below, it is not timed. There are short review sessions in between the course sections. And for being such a basic subject, it was actually very useful to refresh myself on some of the subject matter. Once completed you have access to review the courses whenever you want and upon receiving a passing grade you receive a printable certificate for the credit hour.
