While I am a member of CLARB, I cannot recommend them unless you anticipate working in a number of different States. IMHO, they have a monopoly on the LA licensure program. You can frequently obtain reciprocity/comity in other States if you’re willing to fill out the paperwork and pay the required fees. This does take more time, but it is another option.
Once I let my CLARB registration lapse for several years. In order to reinstate my account, I was required to pay for the three prior years. (This may have changed. I haven’t checked recently).
If you do need registration in other States, I would recommend bumming your fees a little to cover these “extra” charges. I have never used my CLARB account for anything other than obtaining registration in another state.
