Ninth Grade Applicants

Entrance Exam

As part of the admissions process, Justin-Siena usually requires all 9th grade applicants to take an Entrance Exam (PSAT 8/9) as part of the admissions process. This year we have decided to go test optional and will not require the test for admissions.  If you have not taken the exam, you can still apply! Please contact the Admissions Team with any questions.

Application Materials

You must also ask your current school for the following, to be returned by your school to Justin-Siena:

Most recent copy of your 7th and 8th grade/high school transcript.

Principal/Math Teacher/English Teacher Recommendations
  • You will be able to enter their contact information in your admissions application and Justin-Siena will request them directly.

Please contact the Admissions Office to request recommendations.
