ISO is a private Cambridge school in Bausher, founded in September 2008 and serving students from age 3 to 18 on the British curriculum culminating in IGCSE and A Level. Mid-market fees of roughly OMR 2,331 to OMR 4,347 a year.

The school sits on Al Maha Street near Bausher Medical Center with light, ventilated classrooms, a cafeteria, gym and outdoor play areas, plus a shaded kindergarten garden. The Cambridge programme is the academic backbone, and the school has earned Cambridge Learner Award recognition. Long-serving kindergarten teachers come up repeatedly as a strength.

Parent experiences are mixed. Families who praise it cite the KG department and the social progress of younger children. The flip side is concerns from some families about consistency of teaching across years and value for money against newer rivals. Best fit for families looking for a mid-priced Cambridge pathway in central Muscat who can confirm the right teachers in the right years for their child.

  • Public review pool is small. International Schools Database shows a 4.2 average across only three reviews, which is too thin to read into.
  • Reviewers who do post praise the early-years team specifically, including long-tenure KG teachers, and describe a state-of-the-art campus.
  • One review from a parent who had been at the school since KG1 describes the school as having declined over time and become "greed fueled".
  • No meaningful Reddit, Mumsnet or expat-forum coverage surfaces. Available signal sits on aggregator pages with low review counts.
  • British curriculum stream through Cambridge International, with the campus on Al Maha Street in Bausher; positioned mainly to expat and well-off Omani families.
