There are many factors that are considered in the college’s admissions decision. Some factors such as grade point average, standardized test scores, and rigor of course curriculum can be measured. Other factors, such as the college visit, attending an information session, having a positive attitude about the opportunity to attend a particular college or university, and social networking might be considered “demonstrated interest” and are not measurable. Attending college fairs and local events, completing supplemental essays, contacting admissions personal for more information about programs, sending a thank-you note, and completing and early admissions application can all be considered to be showing a high degree of interest in the institution. When you are making the decision to apply to a college, find out whether “demonstrated interest” is a factor in the application process.
