I read through the class requirements for NM on their website. Having just taken the class for CA, it appears the NM class is an hour shorter, all the subjects covered, but NM thinks is not close enough to the NM class for a CA permit to be honored.
The only area where the class might be somewhat short is in conflict resolution training, which TX does pretty well. Everything else is covered well, but maybe that is the school I went to.
Now, CA has its nose in the air and nobody's program is good enough for CA to honor anybody else's permits. A number of states honor CA permits, IIRC.
This is not a good way forward.
Loyalty to petrified opinions never yet broke a chain or freed a human soul in this world — and never will.
