Our Academic Program

At Justin-Siena, we prepare students to succeed in college and beyond by engaging their whole hearts and minds to lead and serve.  

At the heart of the academic experience is our commitment to fostering a personal, caring, and challenging atmosphere in our classes. With an average class size of 23, over 40 AP, Honors, and Advanced courses, and
 electives in engineering and the arts, students learn innumerable ways to problem-solve, create, collaborate, reason, and use their voice with clarity and confidence.
