At some schools, special categories are factors that may give students an edge in the admission process. Some of these categories are:
In-State/Out-Of-State Status
If you are applying to a public institution, state residency will give you an admission edge over out-of-state applicants. Many state schools will publish their in state vs. out-of-state accept rate and profile for applications. While policies vary from state to state and from college to college, some public universities consider children of alumni within their in-state pool no matter where you live. Out-of-state enrollment quotas vary from school to school.
Legacy Status
At many schools, sons and daughters of graduates are given a preferred status in the selection process. Some colleges define legacies based on parents alone, while others may include grandparents, cousins, aunts, uncles, and siblings. Ask the colleges how they define legacy status. Legacy status may give you an edge, but it will not make up for a weak academic record.
Special Talents
Students with exceptional talents in an area who meet basic academic standards may receive special admission consideration. Your special talent may be in music, sports, writing, photography, etc. If you have a special talent, write about it in your application - it may give you an edge.
