The Common Application is used by prospective college students throughout the world to apply for admission to colleges in the United States. Most colleges ask the same questions on their respective applications and the Common Application allows students to skip the process of filling out the applications again and again by letting them fill out one application for multiple schools. Once you create a Common Application Account, there is no way to manually delete it, but you can make sure you no longer receive any correspondence from the colleges listed in your account until it expires and is automatically deleted.
Log in to the account you wish to delete. Click the "My Colleges" link on the left side of the window.
Click the "Remove This College" button under every college in the list. When you click this button, you will be prompted to confirm that you want to delete the college from your list.
Click the "Yes" button to remove the college. Repeat this process for every school in the list. This will ensure that you will not be contacted by any of the schools.
Allow the account you want to delete to sit unused until the end of the application season. The season lasts from autumn to the end of spring. Your Common Application Account will be deleted automatically during summer.
