<p>Race is self identified on the college applications form. You may mark how you identify or even multiple categories, I believe. If my grandmother grew up on a reservation and I visit there I would mark it and Caucasian as they both seem to apply. If college have any special requirements of ‘proof’ needed for that to help you they will inquire and at that time you can explain your connection. DAR is not anything recognized by colleges that I have ever heard.</p>
