Restricted Scholarships are a form of gift aid and may be available to those students meeting scholarship guidelines, as determined by the specific college. Restricted scholarships are available from many colleges and typically have a very specific target recipient and set of criteria associated with them, such as ethnic background, geographic locality, program of study, ancestry, family legacy, and/or descendants of members of certain graduating classes. Those are just a few examples of restricted scholarship examples.
As far as the restricted scholarship application process, you should check with the specific colleges you are applying to and inquire if there are restricted scholarships that can be applied for directly or if students are considered as a result of their financial aid or admissions application. If there is a separate application, be sure to complete it on time and attach any requested supporting documentation.
