Educational Philosophy
At Stoneridge Preparatory School, we believe each student has unique talents. We strive to cultivate each student’s strengths and empower their full potential. We do not expect “fish to climb a tree”; instead, we teach fish how to find the ocean. We provide one-to-one class setting, small classroom setting, or combined classes setting based on students’ needs. Students who need more challenge, students who need extra attention, students who need a flexible schedule, students who just don’t fit regular school socially or academically, no matter which countries they come from, we are here for them. We tailor each student’s study plan and help the student become a confident, open-minded global citizen with professional knowledge and entrepreneurial skills.
Mission
Stoneridge Preparatory School commits to cultivate entrepreneurship skill sets to prepare our students to advance worldwide as global citizens.
