ADA uses prometric to test for the dat.
Once you take the exam, the ada has to do some audits and stuff and that takes 2-3 weeks. Then they send the scores to aadsas(or directly to schools if you did that I think). Then aadsas has to update your application and your new application will be sent to schools. So you will get another mailing date and have to wait 1-2 weeks for it to be sent again.
