The leagues I have known have three levels - rec, select, and travel in increasing order of competitiveness.

What is the difference between house (rec?) and select (not travel but more competitive)?

Lots of teams will still be looking for players. I know DC/MD for boys, so I can't help, but one idea --- you might consider emailing Jonathon Scribner (sp?), the director of HoopEd and the coach of the St. John's girls. He should be very plugged in to local teams and at the very least know where you can look for info. I'd contact through Hoop Ed rather than St. John's just because you could also learn about HoopEd programming (they have a girls camp in the summer, for example).

I know I am very late to look, but does anyone know of any basketball leagues that are either house or select level for 7th grade girls this Spring?
Anything one step below travel would be great.
McLean/Arlington/Washington DC also great.
I know the signups/tryouts may be over, but never hurts to still ask.
Thanks!
