Is it worth joining key club senior year?

Hello my son is wondering whether its worth it to join Key Club his senior year after not participating in it his previous 3 years. Is it worth going through the trouble simply to put another EC on his resume for colleges or not? Any input would be helpful:)

It’s not worth it for the resume. It might be worth it if he wants to do what the club does.

Ok thanks he said he’s not really into the whole enviromental scene but was willing to do it if it meant strengthening his resume.

Do the group a favor. Do not join if you are not interested in participating.
