The ability to alter the Common Application following submission to colleges is a critical concern for applicants. Once the application is transmitted to an institution, certain sections become locked to prevent unauthorized modifications. However, applicants retain some limited capacity to update specific information.
The immutability of the core application aims to ensure the integrity of the admissions process. Allowing unchecked modifications could compromise fairness and create logistical challenges for universities reviewing thousands of applications. Historically, the Common Application system has evolved to balance the need for applicant flexibility with the requirement for a standardized and secure platform.
