5/10GreatSchools RatingParent Rating AverageAs a current teacher and Alumni of CGHS, this is, without a doubt, the worst school I have ever taught and studied at. The primary factor for this is the teachers, especially Diana Van-Wyk. She is the "IB Coordinator" of the school, who demonstrates clear favoritism, laziness, apathy, and sexism. As a counsellor and coordinator of such a prestige program such as the IB, I would expect her to care for her students and support them fully through their academic journey, as would most people. However, since she has joined this school years ago, I have seen a noticeable decline in student mental health, overall happiness, and communication with teachers. This is what inspired me to become a teacher, so I could be everything she isn't. Furthermore, I have received multiple student complaints about her, and her failure of communication as well as her stubbornness. I don't think she understands that the students she deals with are socially maturer than most, perhaps indicating why she refuses to admit she's wrong. It is in the best interest of the school to remove her as a faculty.Teacher Review3mo ago
