"Good School, Room for Improvement"

We've been at CCGS for a year now, and while we're generally pleased with the school, there are a few areas that need attention. The facilities are certainly impressive, and the staff are friendly and approachable. However, we've noticed some inconsistencies in teaching quality and a lack of clear communication about important events and updates.

"Amazing School with a True Community Feel"

We've been part of the CCGS family for three years now, and we couldn't be happier. From the state-of-the-art facilities to the values of hard work, kindness, and respect, everything about this school aligns with our own family's values. Our daughter is thriving academically and socially, and we're grateful for the supportive and inclusive environment.

"Excellent Education, Outstanding Support"

Our son graduated from CCGS three years ago, and we're still in awe of the education he received. The teachers are passionate and dedicated, and the school's commitment to promoting British values, online safety, and wellbeing is truly impressive. We've seen firsthand the impact of the Duke of Edinburgh awards and the CCF(RAF) programs on his confidence and leadership skills.
