Success International School

A small American-curriculum school established in 2014 in Al Mansurah that runs from kindergarten to Grade 8, with plans to add a full IGCSE secondary stream.

SIS Riyadh sits on a 5,000 square metre campus in Khanshal with a 600 square metre indoor play area, two outdoor playgrounds, science labs and a library, and a teacher-to-student ratio of about 1:20. The programme is built on Common Core US standards integrated with the UK's Early Years Foundation Stage in the youngest year groups, and the cohort represents more than 25 nationalities.

Parents praise the day-to-day communication, including subject notes shared in a parents' group, and consistently flag the discipline ethos, the personal feel and the named contribution of individual teachers. The school is currently a primary and middle school rather than a finished K-to-12 destination, so families with children approaching Grade 9 should ask about the timing and credibility of the planned IGCSE expansion before committing.

• Independent reviews are polarised. The international Schools Database has one parent review (Dec 2025) praising daily subject notes shared with parents and prompt teacher replies; YaSchools carries ten reviews averaging, with several detailed Arabic-language complaints alongside short positive ones.
• Communication with parents is the clearest positive theme. The recent ISD review credits the school for sharing what was taught each day in the parent group.
• Negative reviews focus on teaching depth and administration. One YaSchools parent describes the educational outcome as "zero," criticising rote teaching, weak French and Arabic provision, and an unresponsive administration. Another flags poor handling of a KG1 child's first day.
• Positive YaSchools reviews are short and unspecific ("excellent in all respects"), so weight rests on the longer critical posts.
