Mearns Castle High Catchment & Capacity

The rapid growth of Newton Mearns has transformed the school’s logistics. This is the most critical section for new residents to understand.

• Maidenhill Expansion: The brand-new Maidenhill Primary is now a fully integrated feeder school. The increased pupil numbers from this development have pushed the school roll to approximately 1,400 pupils.

Sports Facilities at Mearns Castle High School

Like nearby Williamwood High School, Mearns Castle was rewarded Gold Status from SportScotland. The school offers elite-level coaching in Rugby and Netball, with a massive 3G pitch complex located just across Waterfoot Road.

Mearns Castle has spent the last few years shedding its reputation for aging sports facilities.

The school now boasts some of the most advanced outdoor athletic spaces in East Renfrewshire, largely thanks to a multi-million-pound investment that replaced the old blaes (red ash) pitches with professional-grade surfaces.

While the New Campus refers primarily to the major classroom and wellbeing extension (completing Q4 2026), the sports hub was the first phase to be fully modernised.
