Just for others worried about CLA-R, be sure and look into the Recertify by Points, that Fab mentioned earlier. The CLA was so hard and I barely passed and never want to do it again. Luckily I'm certified until 2023, and already have some points towards certifying again. I realize not everyone wants to put in the time into getting points, and some don't have enough time to get them before certification expires. But if you have a local LabVIEW user group in your area you get 5 points for attending and 10 for presenting. You also get 15 points for participating in an NI beta. This means if you participate in 2 LabVIEW betas, and attend 4 user group meetings a year, you'll have enough points to recertify in 2 years. But of course valid criticism of NI's recertification is welcome.
