CIOs, what are your current professional memberships? And which do you find most valuable?

None. I used to be a member of AMS (American Meteorological Society), ACM (Association for Computing Machinery), IEEE (Institute of Electrical and Electronics Engineers) and PMI (Project Management Institute). Then a few years ago I took a hard look and decided the benefits didn’t justify the cost. YMMV - I think a lot depends upon where you are in your career and where you’re trying to go

I am in K-12 Education. Member of ISTE and CoSN. Both are great. ISTE is more for teachers. CoSN is better for CIO/CTO.
