Grange School is an all through 5 to 16 day and residential School in which pupils, teachers and parents, work and learn together. Grange operates as a not-for-profit, co-educational, English National Curriculum, independent, day school set on beautiful grounds within the Government Reservation Area (GRA), Ikeja, on the mainland part of Lagos in Nigeria. An off-campus “House” has been included to provide a boarding service to parents and pupils. Our spacious campus includes a variety of well maintained facilities which create an attractive environment for learning. Grange School was founded in 1958 by a group of well-meaning British expatriates, to provide education of equivalent standard to that which obtains in the UK. Grange School's population is 430 girls and boys in the Primary Section which is from Reception class to Year 6, between the ages of 4+ and 11. There are 326 pupils in the secondary phase being, Year 7 to Year 11, between the ages of 11 and 16+. The School Policy maintains a class size of 18. The aim of this policy is to ensure that a family ethos is maintained in the school and that at Grange every child is known as an individual. We take pride in our enduring legacy for the provision of a child oriented atmosphere and our aim is to promote matured self-discipline citizens. Our Primary Phase prepares pupils for the KeyStage 2 CheckPoint examinations while our secondary school continues into Key Stage 3 culminating in the Checkpoint Exams and Key Stage 4 which culminates in the IGCSE (International General Certificate of Secondary Education). Both exams are under the auspices of the University of Cambridge Local Examination Syndicate (UCLES). Grange encourages every pupil to discover their own strengths, whether they are academic, sporting, musical or creative. Academic standards are a priority, but we also believe that by educating the whole child we can bring out the best in each and every individual. A vital part of our education presentation is teaching to think independently and creatively. Our pupils are challenged to question, analyse and debate, forming their own opinions, yet upholding an attitude of respect towards others. The school is one of only three in Nigeria to be accredited by the Uk’s Independent Association of Preparatory Schools. (IAPS). The school’s Patron is the Deputy British High Commissioner to Nigeria.

Grange School was founded in September 1958. It was established as a primary school to provide education of a standard equivalent to that which was obtainable in the UK. The idea of a school in Ikeja grew from about May 1957 when a group of interested parents applied to the West African Airways Corporation for permission to rent one of its buildings for use as a school. The group formed Grange Education Limited as a Company to be run as a non-profit making organization, and based on GRA NiGEria, called Grange School. Flying to the UK during the 1950's and 1960's was not as straight forward and smooth as it is today. There were no direct flights to England. At that time, children came to Nigeria to be with their families while on school holidays, and then had to fly back to the UK when schools re-open to continue their education in the United Kingdom. A trip to the UK in those days could take up to two full days, with stop overs in Liberia and Rome. Originally, the school was established to provide the children of West African Air Corporation (WAAC) personnel with education. There was no other school in the Ikeja vicinity, therefore admissions were open to all children in the vicinity regardless of race or employers and catered for children from 4 to 11 years old. Over the years however, our School has expanded to accommodate children of parents who wanted an English National Curriculum Education regardless of nationality or background. The school was officially opened by Lady Robertson, wife of the then Governor- General of Nigeria on the 15th December 1958. During the 1990's there was increasing pressure on the School Board to expand the primary school curriculum up to the British General Certificate of Secondary Education (iGCSE) level. This would accommodate the large number of pupils who either had to leave home at an early age to attend secondary school in the United Kingdom or enter the Nigerian educational system temporarily only to re-enter the British system at Senior Secondary School or University level. As part of the school's 40th Anniversary celebration, in September 1998, the Board agreed to address the need to establish a Secondary Section as a co-ed day school, located adjacent to the primary school. The secondary school building complex facing Harold Shodipo Crescent was to be a symbol of onward-going British traditions in Nigerian society. Due to pressing demands from parents, a residential provision was established in 2006, to support those who struggled to get their children to school in the week. Over the ensuing decade standards in keeping with internationally accepted practices have risen. With the acquisition of new boarding facilities just five minutes from the main school, up to 100 pupils in Y5-Y11 are comfortably accommodated in eight terraced houses in a self-contained compound, In its drive to constantly align itself with the school’s original vision and mission, the Board reaffirmed in 2013 the school’s ethos to be distinctly British within the Nigerian context. ‘British tradition with Nigerian innovation’ became the watch word of the school’s approach. Membership of the prestigious Council of British International Schools (COBIS) was granted in early 2014 and shortly afterwards the school was accredited by the UK’s Independent Association of Prep Schools (IAPS). In late 2013, the Deputy British High Commissioner to Nigeria most graciously accepted the invitation to become the Grange School Patron.
