Applications for admission are accepted from all interested parties throughout the year. Families seeking admission for their child(ren) should communicate with the Director of Admissions. Students applying for admission must complete all procedures before being considered for admission. The school reserves the right to exclude students for academic or disciplinary reasons or to require special supplementary measures at parental expense. In selecting new students, the admissions committee places great importance on the applicant's potential, indicated by testing, teacher recommendation and past performance in prior schools. Other qualities are given significant consideration as well. CGB is looking for well-rounded students of good character, whose families embrace the values and mission of CGB.

It is school policy that the representation of any one nationality within the student body should not exceed 50% between Year 1 and Year 13. The admissions process must respect this proportionality. In all other considerations, all students are eligible for admission if it is believed the school can meet their particular needs and providing there is a place available.

Students with physical, mental or emotional handicaps cannot be admitted unless, in the admission committee’s judgement, adequate provision can be made, and the student can be placed in the regular classroom. Students with learning difficulties may be admitted if it is believed that the Exceptional Needs Department can provide adequate support, and that the student can be placed in the regular classroom.

Students from Year 2 and above seeking admission to the school are required to present English and Mathematics tests. Children who are seeking entry into Nursery, Reception or Year 1 will also need to complete an admissions process. This will involve working with a member of the Exceptional Needs Department or the Head of Foundation Stage and Key Stage 1. The process includes fine and gross motor ability, visual perception, language skills and auditory skills.

Parents will be invited to an interview with the Coordinator of the Department of Exceptional Needs as part of the admissions process for all children applying to enter the school. All students applying to enter years 7 to 13 are also interviewed in English by the Coordinator of this department.

It is the parents’ responsibility to provide additional language support, and to arrange for extra tuition where appropriate, for students whose level of proficiency in English limits their academic performance. Such students may be placed on a conditional matriculation. Generally, students who are not minimally fluent in English as a second language will not be admitted in year 10, 11, 12 or 13. Students who are not fluent in English as a second language will be regularly and systematically evaluated. Continued enrolment requires the demonstration of consistent and significant English language acquisition as determined by the school.

All admission decisions are based on whether the school can provide a programme that meets the individual needs of the student. If these needs are felt to be beyond those which can reasonably be provided by the school’s staff, a student may still be admitted, if special on-campus tuition and/or external professional help can be made available which will permit the student to be placed in the regular classroom and not cause disruption to the classroom administration. The cost of such additional help would be the responsibility of the parents.

Age and previous schooling provide the starting points for a discussion on placement, but the student’s needs, academic record and the school’s initial assessment are other factors that will also be considered.

Pupils who pass the English and Mathematics admissions tests shall be placed into the following year groups according to their age.

New students are given standardised tests in English and mathematics to determine their level on entry into the school. This level can then be used to track progress made by the individual during their time in the school.
