The Grange Secondary School endeavors to provide a qualitative British education in a happy, caring and supportive environment. We believe that this can best be accomplished when children feel valued and are treated with dignity. Our curriculum, both in and out of the classroom, provides experiences for children which are academically, socially, physically and aesthetically challenging, while promoting in them a spirit of tolerance and understanding towards others. Our children are given opportunities to develop open and enquiring minds through problem solving and co-operative learning activities. At the same time we believe in the need for an academically demanding program which emphasizes traditional values of hard work and self discipline. We endeavour to value pupils for their achievement and turn failure into future success.

We believe that children learn best when they are actively engaged in their day to day learning, and where they are given considerable responsibility for their studies. We value what children achieve rather than focus on their failures. Ultimately, we believe that when children enjoy school, they will make accelerated progress towards intellectual maturity, while taking advantage of the social and cultural activities which we share with them.

We value parents, engaging them as full partners in their child's education and we do everything we can to make them feel welcome in, and committed to the school.

We also believe in the need to nurture and develop all our staff both professionally and personally, since it is they who create the climate in which our children will learn most effectively. We enrich our staff by providing opportunities for personal and professional development both in-house, within Nigeria and where possible training abroad. It also means that we keep up to date with educational developments, particularly in the United Kingdom to ensure that we uphold a British tradition.
