Typically its just bringing us up to date on code changes wrt keeping endorsements current, best practices, which parts of IPC/UPC have ammendments, etc. very rarely do we get actual changes in methodology, like this last year when the ASTME changed up the approved procedure for soft soldering copper pipe, and silver bearing solder brazing. It eventually gets updated for all the up and comers when they test for practical exams.

No ‘practical’ stuff, nearly every bit of it is clerical.

Texas is sort of on its own when it comes to plumbing. We have the most stringent testing requirements in the US. Other states have modeled their tests and procedures to be more like ours. Some years back we had a scare, where the state was going to defund the current plumbing board, and roll us under the Dept of Licensing and Regulations purview, which would have rendered a statewide license null, basically every city/county/township would have its own licensing fiefdom. As is, i work in five or six towns/fishing villages around me, probably the same amount of different counties. Id have to hold between 5-10 licenses, and keep up with each locale’s various requirements to be current to work there. I like to keep up to date with this stuff since it directly affects my livelihood, and the only way to get the current info is from the instructor of the class i am in right now, because he’s a bigwig on the state plumbing board.
