Full disclosure labelling. I like that!
So for example:
My Generation
- P. Townsend (didn't write the bass line)
Every breath you take
- G. Sumner (didn't write the guitar part)
Etc.

I'm not an expert you understand, no really I'm not, but off the top of my head from what I remember: managing weight and balance, reducing fretting-hand tension, optimizing reach, breathing and performance anxiety.
Bit of a minefield. There's no 'regulation' just because someone is teaching bass doesn't necessarily mean they know about good technique. Plenty of teachers are great players who are passing on their own bad habits 😆
If i was paying someone to teach me some bass, minimum requirements would be theory, improvisation, and Alexander technique.
YMMV.
As an aside to this thread, remember these pedals don't come with a rule book. I have the one above (the only one from the range that Jack doesn't seem to have 😆) and last night at rehearsal we used it with the trumpet. The octave down setting made for a useable tenor sax sound, and the group setting made for a useable brass section type sound.
"I was at Eric Clapton's wedding when I joined the Beatles" Chas laughs.
"Me and the missus got invited an there was a marquee set up in the grounds with a stage, amps and drum kit in case anyone felt like getting up and having a jam.
"Anyway, this little kid started bashing the drums and called over to me saying "C'mon Chas, sing Gertcha for us". So I go up with the mic and started singing some rock and roll stuff. I looked up and there was Ringo sitting there smiling at me. The next thing I knew Paul was plugging in his bass and George slipping a guitar over his head. And there's me in the middle thinking "I'm the fourth flippin' Beatle here!"
