You can contact the main office of RID and they will tell you which programs are currently available. Many college programs have closed or changed in the last few years.
Go to RID -, RID's homepage. In the lower left part of the page is a purple box labeled "Search Tools". Click on the choice labeled "Find Interpreter Education Programs".
The page that comes up will offer some blank boxes for refining your selection. To go state by state, just select what level of education you're seeking under 'Programs', then pick a desired state in the 'State' column. Click search.
