Some schools use ApplyWeb to inform applicants of their admissions decision, while other schools notify their applicants through other means. To determine how your school will be informing you of your admissions decision, please contact their admissions office directly.
If the school to which you have applied has notified you that they have assigned you a decision letter, you should be able to check your application's status and decision letter by logging into your Activity Page.
A button to access your decision letter should appear under the appropriate application.
If there is no decision button, contact that school's admissions office to let them know. It might be that they have either yet to give you permission to view the decision letter, or the decision letter has not been assigned to your account. Their contact information can be found on their website.
