Curriculum
From ages 2 to around Grade 12, RISR uses a modified American curriculum that progresses through developmentally aligned standards in subjects such as English, mathematics, science, social studies, arts, technology, and physical education. In the Early Years (ages 2–5), the program blends the Reggio Emilia approach with the Creative Curriculum Units, focusing on child-led exploration across developmental domains. The Elementary School (Kindergarten–Grade 5) follows an inquiry-based model, grounded in internationally recognized standards, alongside social-emotional learning through the Second Step program. In Middle School, learning shifts to integrated, flexible instruction, supported by advisory programs and character development frameworks such as Responsive Classroom and Restorative Justice. At High School (Grades 9–12), the curriculum adopts a STREAM (Science-Technology-Recreation-Engineering-Arts-Math) approach, allowing students to choose Advanced Placement (AP) courses, and prepares them for a future diploma; the school is also pursuing IB authorization.
