Step I: Inquire

Complete the Inquiry Form

Complete our inquiry form before scheduling a visit. Once you fill out the inquiry form, domestic applicants will receive our viewbook; international applicants view it online.

If you have a particular interest in athletics or the arts, please fill out an athletics interest form and/or an arts interest form. Your information will be sent to the relevant Middlesex coach(es) or teacher(s).


Step II: Interview

Schedule an Interview

An interview is not required, but it is highly recommended. A visit to campus helps us get to know you, and it helps you get to know Middlesex. If you are an international student for whom English is not your native language, please refer to our International Applicants page for specific instructions about scheduling an interview.

Please call the Admissions Office at 978-371-6524 to schedule an appointment, or you may email us at [email protected]. On-campus interviews are offered every day that class is in session. For appointment times, please see our Admissions Appointments page.


Step III: Complete Testing

Schedule a Test Date

Test scores must be sent to Middlesex directly from the testing service

The Secondary School Admission Test (SSAT) or Independent School Entrance Exam (ISEE) is required for applicants to grades 9 and 10. Applicants for grade 11 may submit current year SSAT, PSAT or SAT scores.

  • 2017-18 Test dates for the SSAT are October 14, November 11, December 9, January 6, & February 3.
  • The Middlesex SSAT code is 5068; for more information about the SSAT, contact S.S.A.T.B. at 609-683-4440, www.ssat.org
  • The Middlesex ISEE code is 220-650; for more information about ISEE, contact 800-446-0320, www.erbtest.org

In addition to SSAT or ISEE, the TOEFL is required for all international applicants whose primary language is not English, unless you have studied in an international school in which English is the language of instruction for more than two years. In general, successful applicants to Middlesex have a high proficiency in English, which is typically demonstrated by a TOEFL score of 100 or higher.

For more information contact TOEFL at 609-771-7100, www.toefl.com. The Middlesex TOEFL code is 8720

Character Skills Snapshot 

All applicants to Middlesex are strongly encouraged to take The Character Skills Snapshot, a 30-minute online evaluation of character skills not currently measured by cognitive standardized tests.  The Character Skills Snapshot is designed to measure essential character skills that we seek to nurture in our students, such as resilience, intellectual curiosity, and open-mindedness.

There is no charge to take The Character Skills Snapshot when you register for the SSAT.  Students planning to take the ISEE must contact Middlesex at [email protected] to gain access to The Snapshot.  There is a $25 fee for ISEE test takers.  Fee waivers are available.


Step IV: Apply

Complete an Application

All applicants apply online, using either the Middlesex application through Gateway to Prep Schools (Gateway) or the Standard Application Online (SAO).  We do not have a preference between the two applications, but we require that applicants submit materials through only one application platform.

The applications require a Candidate Profile or Student Biographical Form, Student Essay Questions, Parent Statement, recommendations from current English and Math teachers, a Principal/Counselor Recommendation, and a transcript report, including current grades and grades from the previous two years.  Through Gateway, you may submit an optional Special Interest Recommendation or a Personal Recommendation.  Transcripts and other materials not submitted through Gateway or SAO may be emailed in the format of a PDF to [email protected].

We do not accept original artwork, scrapbooks, DVDs, or CDs. Instead, please provide additional (voluntary) Athletics or Arts multimedia supplements through the Multimedia section of the Candidate Profile online. Do not delay submitting your Candidate Profile because you are waiting for a website or file to be prepared. In the Multimedia section, note that a link or file will be provided later. Email your link or file to [email protected] with your full name, date of birth and the words “ADDITIONAL INFORMATION” in the subject line of your email.

The non-refundable application fee is $60 for domestic applicants and $120 for international applicants, payable by check or credit card using the Gateway application.

The application deadline for all applicants is January 31, 2018.  While we prefer to receive your parts of the application by January 31, we recognize that grades, recommendations, and testing may follow, and we promise to issue March 10 decisions to all students who have completed their applications by February 10. If you have questions regarding the timing of your application, please call the Admissions Office at 978-371-6524.

The Financial Aid application deadline is also January 31, 2018.  We encourage all families to apply for financial aid, if they believe they will need any level of financial support during their child’s tenure at Middlesex.  If a family does not apply for aid or qualify for aid upon admission, it is unlikely that the family will receive an aid award in subsequent years, unless there is a significant change in that family’s financial circumstances. Visit our Affording Middlesex page for more information.


Step V: Track Your Application

Track Your Application

You may track your application through the Gateway website. Rest assured that, if you sent your test scores through SSAT, we received them.

It may take up to a week for your application materials to be processed, so please be patient. Thank you!


Step VI: Receive Notification

When Will I Know?

Applicants will receive email notification of their admissions decision on March 10.

Accepted students must sign and return enrollment contracts, with specified payment, by April 10 in order to reserve their spot at Middlesex.
