Project Northstar provides tutoring for students in long-term temporary housing in Washington, DC. Tutoring takes place for about two hours a night most days of the week at six sites around the city. You can pick which site is most convenient for you. Best part is -- Project Northstar works hard to empower the students and incorporates the tutors to create a close-knit, supportive community that the kids seem to really respond to. I've been tutoring there for six months. It's been hard at the times I didn't know how to deal with misbehaving kids, but the staff of Project Northstar was always super helpful. I very much recommend it.
