The British International School and Montessori Education Freetown was established  in September 2009 by its founder and owner Jenny Condron. It was formerly known as International Montessori School Freetown. 

In 2010 the school was accredited by the Ministry of Education Sierra Leone and in 2012 the school became accredited as a Cambridge International school by Cambridge Assessment International Education.

We have since then adopted the Cambridge Primary school Curriculum to facilitate our primary and secondary school program. Our programs support children aged 16 months to 16 years. The primary school program follows the Cambridge primary curriculum while in the Secondary School follow the Cambridge Lower Secondary curriculum and Cambridge IGCSE curriculum.

More information about the Cambridge Primary and Secondary Program can be found at

The British International School and Montessori Education caters for a diverse community of learners representing more than 40 nationalities making it a truly International School.

Our teaching staff are sourced both locally and internationally thus creating a harmony of culturally blended experience for the children, parents and staff.

The British International School and Montessori Education is a proud member of the Council of British International Schools (COBIS) and the International Montessori Council (IMC).

Children at B.I.S. work together in harmony and our team of dedicated staff are equally competent in ensuring that the children are happy and well looked after.

The school provides facilities for children of ages 14 months to 3 years in our Nursery. The nursery is divided into two main groups. Junior Babies and Senior Babies.  Children in Nursery are introduced to the Montessori programme to develop and nurture the sensitive periods of development.

Children in our Montessori preschool group are aged 3 to 4 years and 4 to 5 years in the Kindergarten group. In our primary school section of Key Stage 1 and 2  the age group of the learners are 6 to 12 years with classes ranging from primary 1 to primary 6. 

In our  Secondary Section which comprises of Key stage 3 and 4 the learners are aged 11-16 years old.

Our classrooms are bright and airy while Our play areas include a safe and child friendly  indoor and out door play areas. Other facilities in the premises are a library, music and ICT room.


The Montessori approach is a unique method of introducing the child to a life time of enjoyable learning. Special materials, largely manipulative in nature, help to answer the child’s developmental needs and to enable the child to experience the excitement of learning through his /her own choice, thereby developing natural desire for learning.
