World-Class Curriculum

We offer Inquiry-based International education which prioritizes excellence in academics and overall value-based development.

1) Inquiry-Based – Our students get the chance to ask questions, explore their curiosities, and engage with ideas through real-world and role-play scenarios. 

2) Student-Driven – Learning through student-driven projects encourages students to take ownership of their learning, allowing them to focus on their individual strengths and passions. 

3) Personalized – With our optimal student–teacher ratio of 18 or fewer, teachers can give each learner the attention they need and adapt lessons to suit individual needs, learning styles, and pace.

4) Rigorous – Applicants must pass an assessment test to be admitted, and our students are guided so that they can receive a passing score before advancing to the next grade. 

5) Holistic – Our mainstream curriculum, subject electives, and after-school clubs develop the student’s values, character, and skill development by encouraging traits in the learner profile.

6) Internationally Recognized – Our curriculum takes the best from the UK, Australia, & North American schools, and the International-Bachelorette (IB) is recognized by top universities around the world.

7) Value-Driven – Students are taught universally held international values such as compassion, perseverance, and inclusivity.

8) Expertly Delivered – Our certified, experienced, & IB-trained teachers deliver quality education, supported by the best practices of the Global Schools Group (GSG).
