I am an active member of a local Women in Technology group, and it's been interesting to watch the metamorphosis over the past three years. At first it was a core group of women who really leaned on each other for resources, support, connections, etc. in fields that are typically dominated by men. Many of those women helped me tremendously when I started my own tech company.
Now the monthly meetings have a ratio of about 2/3 women and 1/3 men. We've attracted some excellent guest speakers, educational classes, etc., that men have opted into taking part in. We've always welcomed men, but the focus has been on helping young girls and career women succeed in fields previously dominated by men.
I imagine the motive behind this program is similar, so I'd definitely encourage your son to apply.
