Need is not always a consideration with a scholarship. It depends on the scholarship and the criteria. Some scholarships are need-blind and entirely merit-based… awarded to the most-qualified applicant regardless of financial need. Some scholarships do take financial need into consideration. You should read the criteria for the particular scholarship you are applying for.
But remember it is an application, not an automatic acceptance simply because you filled out a form. You must meet all the requirements, whether that means additional essays, interviews, etc. and then your application “package” will be considered. Even then it may or may not be selected for the scholarship depending on the quality of your application as compared to the other applicants.
