Brian Nyabvure Physical Education Teacher

Brian Nyabvure

PE Teacher


 I studied Sports Management with Boston City Campus in South Africa. I completed my cricket studies in Zimbabwe and I am a Level 2 coach with the Zimbabwe Cricket Union. After completing my cricket courses I went on to do my rugby studies and qualified as an IRB Level 2 Rugby Coach. Football was a sport I had played for years and as a result I was fortunate enough to go and study it in Manchester, England. I studied Football Fitness, Match Analysis and I am a qualified FA Coach with a valid coaching licence. As a Physical Education teacher and Sports Coach I have eleven years of experience, working at a private boarding school in Zimbabwe.


I believe that any pupil can be the best at what they want to achieve if they put their mind to it and are surrounded by people who believe in them. My aim for all my pupils is to ensure sport plays a part in developing the whole child.


Apart from coaching, I was a dorm master for senior boys at a private boarding school. During my high school holidays I worked at a law firm as a personal assistant, lodging documents.

I’m also involved with establishing fields and gardens, and liaising with various persons in FQML to develop the school facilities. I am assisted by the very capable Ruddy Mukaro and Mpandika Phiri, who were with me in the Zambezi Valley for many years, who also help in making the lives of Educore employees in Kalumbila as comfortable as possible.
