Initially catering to students from Kindergarten to Grade 7, the institution expanded to encompass classes up to Grade 12 starting from the 2013-2014 academic year. Celebrating the recent graduation of our 10th batch of seniors marks a significant milestone in our history.

In its inception, ISO welcomed students at a temporary, spacious campus in Madinat Al I’lam. However, in September 2021, it made a pivotal move to a cutting-edge, brand-new campus situated in Bawsher.

Originally offering a comprehensive American Curriculum, ISO transitioned to the Omani Bilingual General Education Diploma curriculum from the academic year 2013-2014. Subsequently, in the academic year 2014-2015, ISO introduced the Cambridge IGCSE, Advanced Subsidiary, and Advanced Level Syllabi. This evolution broadened the educational offerings available to our students.
