Welcome to Commonwealth School's application process! Commonwealth uses an online application system called Ravenna. To apply, please register with Ravenna and create a basic profile. Then, select "Commonwealth School" from the School Directory to begin our process.

The application fee is $60 for U.S. residents and $120 for international applicants. If the application fee presents a challenge to your family, please contact our office to request a fee waiver and we will gladly provide one.

If you indicate in the application form that you wish to receive information on financial aid, we will send you instructions by the end of the calendar year. Both admissions and financial aid decisions will be released on March 10, 2020.

If you are interested in admission for the fall of 2020, please contact us before submitting an application. Although our deadlines have passed, we are willing to consider additional applicants on a case-by-case basis.
