DeeDee, I do believe that all US dental schools will accept the Canadian DAT in place of the US DAT if you are a Canadian applicant. While I'm not POSITIVELY sure if this applies to every last dental school, I do know that all of the big private schools that we Canadians normally apply to (NYU, Columbia, Penn, Temple, Tufts, BU, CWRU, UMich, UDMercy, Harvard, Marquette etc...) will all accept Canadian DAT scores. If you are somehow permitted to apply to and attend some of the state schools, you may want to check with them b/c they may have more restrictive requirements regarding the DAT. Hope this helps,
MDP
