Step 1: Request Information

Step 2: Attend an Admissions Event

Step 3: Schedule an Interview

We can’t wait to get to know you—and for you to get to know us—during your online interview. You and at least one parent or guardian will connect with a member of the admissions committee and begin a dialogue about what might make Commonwealth the perfect fit for you.

To set up a Zoom interview, please call 857-505-1274 or email admissions@commschool.org. Deadline: February 1.

Step 4: Apply

Please note that our application deadlines for Fall 2023 entry have passed, and it is unlikely that we will accept any additional applications. We would, however, be glad to include you on our email list as families' plans sometimes change and we may find ourselves in a position to consider late applicants in the coming months. If you would like to keep in touch, please complete our online inquiry form.

Commonwealth uses an online application system called Ravenna. Start by registering with Ravenna, creating a basic profile, and selecting "Commonwealth School" from the School Directory. (We also offer the option of downloading and printing an application to fill out by hand. Please contact us to learn more.) 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 us to request a fee waiver, and we will gladly extend one.

Deadline for international students: January 1 (Learn more about admission for international applicants.)
Priority deadline for domestic students: January 1*
Standard deadline for domestic students: February 1

*Students who submit the preliminary application form in Ravenna by January 1 will be prioritized in visiting Commonwealth in person to tour and attend classes.

Step 5: Visit

There are two options for applicants and families to get to know Commonwealth better and to complete the application process:

1. If you apply on or before January 1, you can spend a partial day at Commonwealth taking a student-led tour of the school with one or two parents/guardians, attending classes, and completing a writing exercise that will become part of your application. If you cannot visit in person, we would be happy to arrange an alternative virtual experience (see below).

2. If you apply after January 1, you will be able to complete the process with us virtually. We encourage you to sign up for a virtual Q&A session with our student ambassadors, and we will set up a virtual appointment during which you’ll complete the writing exercise that will become part of your application. We will do our best to accommodate an in-person visit should space remain. While we wish that we could offer an in-person visit to every eligible applicant, we need to be mindful of building and classroom capacity.

Visiting in Person:
In the interest of safeguarding the health of our students, faculty, and staff, as well as visitors, applicants and parents/guardians must either be fully vaccinated against COVID-19, as recommended by the CDC, or wear a mask while inside our building. Please consult our COVID-19 guidelines for more general information about Commonwealth’s safety measures.

Visiting Virtually:
A virtual “visit” includes the opportunity to connect with current students through a Zoom Q&A session and a separate appointment for completing a writing exercise. We also recommend exploring our school building through our virtual tour. It’s important to note that students who complete virtual visits—for whatever reason—will not be disadvantaged in the application process.

Step 6: Submit Additional Materials

As part of your application, you will need to submit a transcript, three school recommendations, and other materials. You’ll find detailed instructions below.

Standardized Test Scores

We require prospective students to submit either Secondary School Admissions Test (SSAT) or Independent School Entrance Exam (ISEE) scores, as they provide the admissions committee with a standard metric among applicants. We consider test scores within the context of each applicant’s overall application and educational background. Deadline: February 1.

Commonwealth’s SSAT code is 2542, and our ISEE code is 220222.

If students have taken any other standardized tests—MCAS, ERB, MAP, etc.—during middle school, we encourage them to share those results, too. Typically, upon request, a student's current school can send these score reports directly to Commonwealth.

Information on the SSAT

Please see below for details on testing options. Students are welcome to take the SSAT in whatever format they wish. If the SSAT registration fee poses a financial challenge for your family, please do not hesitate to contact us for a fee waiver.

We welcome (but do not require) students who have taken the Character Skills Snapshot, an online character development assessment through SSAT, to share their reports with us.

SSAT Testing Options for Domestic Applicants

Paper-Based SSAT: Paper-based testing will be available for the 2022–2023 school year, and registration opens on August 1.
Computer-Based SSAT at Prometric Test Center: Students may take a computer-based version of the SSAT at a local Prometric Test Center location.
Computer-Based SSAT at Home: A secure, browser-based version of the SSAT will be available.

SSAT Testing Options for International Applicants*

Please note that SSAT options vary from country to country; you will find a partial list of offerings here. We encourage you to contact us with questions.
Paper-Based SSAT: Paper-based testing will be available for the 2022–2023 school year, and registration opens on August 1.
Computer-Based SSAT at Prometric Test Center: Location permitting, students may take a computer-based version of the SSAT at a local Prometric Test Center location. Please note that this option is not available to students in China, Hong Kong, Korea, Vietnam, Laos, Jamaica, and Myanmar.

*Unless they attend a school in which English is the primary language of instruction, international applicants should plan to take the Test Of English as a Foreign Language (TOEFL) in addition to the SSAT. Learn more about admission for international students.

Recommendations

Commonwealth requires recommendations from three current teachers:

One from an English teacher;
One from a math teacher; and
One from your head of school, principal, guidance counselor, or placement counselor.

Recommendations should be submitted through Ravenna's online recommendation system; directions can be found in your Ravenna application portal.

Personal recommendations—from a music instructor, coach, past teacher, etc.—are accepted but not required. Should you wish to include a personal recommendation, please limit yourself to one.

Deadline: February 1.

Transcript

We ask applicants to complete Ravenna's transcript release form, which they will turn in to their current school. Please note that, as this is a shared form amongst the Boston-area institutions that use Ravenna, it is only necessary to submit the form, which you will find in your Ravenna application portal, to your current school once; simply check off all of the Ravenna schools to which you plan to apply.

Transcripts should include full-year grades for 2021–2022 and partial-year grades for 2022–2023. Many schools will also include grades from 2020–2021, which we gladly accept. School administrators should either upload transcripts to Ravenna or send them directly to Commonwealth by email (admissions@commschool.org) or mail (151 Commonwealth Avenue, Boston, MA 02116). Deadline: February 1.

Writing Sample

We ask applicants to submit a writing sample that they have written this school year and that meets the following requirements:

It should come from an English, history, or social studies class.
It can be either a draft or the final version.
While it does not have to be graded, it should include some kind of teacher feedback in the form of a completed rubric, comments, etc.
If it’s not possible to submit an essay from this school year, please select a piece of writing from the second semester of last school year.
It should be uploaded to your Ravenna account; you will find instructions in your application portal.
