The Senior School is a really happy place. We have 12 forms with approximately 16 children in each class. 

Students wear standard school uniform Monday – Thursday inclusive, which should all be clearly labelled with your child’s name. Friday is non-uniform day. 

During year 9 students prepare for and enter their first formal public exams, the University of Cambridge Checkpoint Examinations. Mock exams take place in February in preparation for the real exams in April/May. Students also make the major decisions concerning which IGCSE and GCSE subjects they will opt for. Along with close guidance from subject teachers and our Careers Adviser, children and parents explore what each subject involves before making their choices towards the end of the Lent Term. 

Students are prepared for IGCSE exams in their final two years at the school. All pupils  sit a GCSE in  Maths and IGCSEs in English Language, English Literature and Co-ordinated Sciences or the three Separate Sciences. We recommend that they take at least one foreign language as well. 

They can then choose between a wide range of other subjects at IGCSE and GCSE including:

French, German, Spanish, Latin, History, Geography, RS (Philosophy), Drama, Psychology, Media Studies, Art, Film Studies, Business Studies, Music, PE and ICT.

The Cambridge IGCSE is the world’s most popular international curriculum for 14–16 year olds. The examination centre, run by the University of Cambridge states the following:

Cambridge IGCSE is an international curriculum that develops students’ skills in creative thinking, enquiry and problem solving, and gives them excellent preparation for the next stage in their education. Schools can offer any combination of subjects. Each subject is certificated separately. Over 70 subjects are available, offering a variety of routes for learners of different abilities.

Schools worldwide have helped develop Cambridge IGCSE. It incorporates the best in international education for students at this level. It develops in line with changing needs, and is regularly updated and extended. Cambridge IGCSE teachers can draw on excellent resources, training and advice from subject experts. Cambridge IGCSE has wide recognition from higher education institutions and employers around the world as evidence of academic ability. 

Our exam results are consistently high, with students really benefitting from the small class sizes. Each year, we are delighted with the achievements of our children, with the most able gaining 10 or more top grades and the less academic students achieving so much higher than they expected. 

All pupils are encouraged to take part in our Duke of Edinburgh Award Scheme and in the summer term of Year 10 they spend a week on Work Experience.

Every year the IG1 form spend a week out of school with various employers discovering the world of work.  We are grateful to the many employers in the area and in London that offered a placement to one of the students this year.

All the students kept a note of their experiences and the new skills they had to use in their jobs for the week.

Work experience is part of the careers education at CIS and it seems the whole form had a great week and they have all made a very positive impression on the local employers. Well done to all the form for an enjoyable, if at times challenging, week of work.
