Charles Dale Memorial International School (CDMIS) is the secondary school arm of Bereton Montessori Nursery and Primary School located in Port Harcourt, Rivers State. As part of Bereton Montessori School’s 25th anniversary in September 2003, the Management of the school decided to take a further step to achieve its goals by further training pupils to secondary school level. Parents were concerned about the future of their children/wards since it is without doubt that there are not enough Secondary schools of International standard in Rivers State and the Niger Delta sub-region. They had to travel to other parts of Nigeria in order to get high standard secondary schools, which they desire.

Charles Dale Memorial International School is named after Late Mr. Charles Ernest Dale, a renowned British Educationist who contributed greatly to education in Nigeria. Late Mr. Charles E. Dale is the father of the School’s founder, Chief (Mrs.) Victoria O. R. Diete-Spiff. This honour was to commemorate the 40th Memorial of his death in 2004 with laying of the foundation stone of the school on 25th May, 2004.

Construction of the school’s state-of -the-art facilities went on for two years to achieve an Administrative building, Modern Classrooms, Science laboratories, Workshops, ICT room with internet access, Art rooms, Music studio, Sport field, Library, Student hostels, Staff residence, Principal’s residence, Clinic and Dining hall.

Charles Dale opened fully for operations on 30th September, 2006 with 14 teaching and 7 non-teaching staff and 32 students comprising of 20 boys and 12 girls, which grew to a total of 38 students by April 2007.

As at September 2007, the student population grew favourably to 149 students ranging between Years 7 to 9 with our classes still maintained at a maximum of 25. This indicates a 366% growth within 12 months. We have progressively grown to 237 as at January 2009. We give all glory to the Almighty God.

We run an International curriculum which is based on both the Nigerian and British curricula. In Year 9 students will sit for the NECO Junior Secondary School Examinations (JSCE). At the end of the Senior school, students will sit for the Senior Secondary Certificate Examinations (SSCE). We are accredited as a Cambridge Centre for the Cambridge Lower Secondary Programme and Cambridge Checkpoint tests in the Year 9 and the Cambridge IGCSE in Year 12.
