Apple Green Private School, Muscat

Small Omani-owned private early-years and primary school in Al Athaiba, Muscat, founded 2009 and described as bilingual Arabic-English with an EYFS-style framework. Parent base is local Omani rather than the embassy-circuit expat crowd.
Five Google-sourced reviews on International School Advisor average and are around six years old. One parent said the school is "one of the best schools I ever went in my life," another simply called it an "excellent private school from nursery to grade 6."
The substantive review is more useful: one parent said safety and welfare are clearly a priority, that teachers and students seem happy, and that parent-teacher communication is constant. The same review flagged the absence of school transport as a downside.
Reddit and expat-Muscat forums do not surface the school by name. There is no second pool to triangulate against.
Treat as a small, locally-rooted school with a positive but very thin online signal. Useful for parents living in Athaiba, less so as a comparator against larger Muscat international schools.
