From Our Students

  • I would like to mention the following aspects of our school: Our school's small class size allows teachers to communicate with students completely and answer students' questions quickly. All teachers are responsible and willing to help students with studying in a prompt manner.

    Review from Greatschools.org

  • Students have a wide variety of study options to choose from, from in-person or live online, from regular, Honors, and AP courses to test preps. The school system is designed so it can flexibly support and help students

    Review from Greatschools.org

  • While the school was relatively small when I was a student at the school, the environment made me feel involved in many activities and helped me make friends

    Review from Greatschools.org

  • The principle, Mr. Lee, checks in with each student regularly to make sure that we're staying motivated and encouraged which helps when the course works becomes heavy.

    Review from Greatschools.org

  • This school was honestly a life-saver for me. The staff here is incredibly supportive; each teacher is very knowledgable in their respective field of study and keep the students on task.

    Review from Greatschools.org

  • Principle, Mr. Lee, is always on each student's case when it comes to finishing course work (in the best way). If he saw that my pace was slowing down, he'd encourage me to finish what I started, which I was ultimately able to do. Overall, coming to this school saved my grades (no exaggeration) and I'd recommend it to anyone who's willing to put in the work!

    Review from Greatschools.org

  • How many schools can say that 100% of their students have gained admissions to major universities? My son was one of those students. When he transferred to Solomon, he had a 3.3 GPA and little chance of getting into any of the top colleges. But, by the time he graduated, he had a 3.93 GPA and offers of admission from top 5 universities

    Review from Greatschools.org

  • I attribute my son's success to a school administration that genuinely cares for and supports their students, and excellent teachers who create a high-achieving, yet encouraging, academic environment. I could not be happier with Solomon International School and the success they helped my son achieve!

    Review from Greatschools.org

  • I joined this small but warming community in my sophomore year. After almost two years studying here, I would like to reflect on the path of my learning and share a few points about Solomon helped me achieving my academic goals.

    Review from Greatschools.org

  • The population of the classes is small, and the teachers are always there when you need them. I remember a picture of a meme posted on the wall of our math classroom. On it says: “have questions? Just ask.” In the class room, I never feel hesitate to ask, and my questions get solved right away without having to wait until after class or tutorial time.
