We are grateful that you are making the choice to either enroll or re-enroll in Arlington Catholic. We are excited about some changes for next year including a Fine Arts requirement; a new BYOD program that will allow students to retain their iPads or bring other approved devices; and, new courses in AP Computer Science, Art History, Biotechnology, Engineering, Music, and Theater Arts, while also expanding our Latin and Italian offerings.

The enrollment process makes use of a 'enrollment responsible' parent. If you follow the directions below and do not see a way to start an enrollment packet, then the email you are using is not that enrollment responsible parent. That can be easily changed as sometimes the first email on an application is not the same as the person looking to complete the packet. Simply email and that change process can be completed in 30 seconds. Please let us know if you have any questions or need any help to complete the process.

The online enrollment process allows you to verify the biographical information on file as well as for the family and takes approximately 15 minutes to complete. Your information will be saved if you need to quit and come back later. The enrollment process is not complete until you pay the $300 registration fee at the end.

Attention NEW students (Class of 2022)-- We welcome you to the Arlington Catholic family as well. You may either follow the link in your acceptance email, the 'Congratulations' link at the top of our web page or email for further assistance. 

Attention current Saint Agnes School students coming to AC next year- your Parents Web and re-enrollment will say Saint Agnes School because that is the school you are presently attending. Rest assured that registering there is the correct process to enroll at Arlington Catholic. 

Re-enrollment is still occuring. Students will not be scheduled for courses until this process is complete.  

If you have any questions about the re-enrollment process, feel free to contact us at 781-646-7770 or email
