Does anyone know where to get training on all the is and outs of residential LEED certification?

Check your local continuing education places, community colleges, adult schools, trade group seminars, in your area. In the Eastern PA area there are a number of classes offered at schools in the area by local practitioners. Also, check at the Leeds site and the NAHB sites.

If your in Georgia try Southface, FSEC in Florida hold frequent trainings as well
