I am a bit rogue, and buy PDF books for my team on trendy tech, some applicable to their day to day, but mostly what is trendy in job postings.
I don’t try to hold them back.
I was also able to send a team member to SF earlier this year for a week to a ML bootcamp.
And last year, I got a few members from multiple teams to attend a 3 day state security con.
Beyond that, I do try to be a mentor, and try to engage by answering why we do what we do and the historical context of how we got there.
I guess I also have some informal documents that are part of a curriculum, but there is no official single source of truth.
