Monday 6 - Friday 10 July 2020

For 11+ entrants and parents i.e. Year 5. Entry to Year 7 in Sept 2021.

We invite prospective students and parents/carers to find out more about CCHSG by visiting the school for a tour during our Open Week. Tours are led by our current Year 7 students.


CCHSG is one of the highest performing schools in England winning national awards for both attainment and student progress

CCHSG is delighted to announce that following the publication by the Department for Education of the figures for last year's GCSE results, according to the Telegraph ranking, CCHSG students performed the best nationally in 2018.  The school shared this top slot with Queen Elizabeth's School, Barnet. These figures are based on the percentage of pupils achieving five or more A*-C/9-4 grades, combined with the DfE's Progress 8 measure.  

Please click on the link below for more details.

If a student makes the progress expected, the school’s Progress 8 score is 0.0. A score of 0.5 means pupils made, on average, half a grade more progress across their subjects than expected. CCHSG has a Progress 8 score of 1.22, which is particularly pleasing given that students join us already achieving at a high level.

We are extremely pleased for our students and truly grateful for the support provided by our staff, students, parents, carers and governors. 


We congratulate Year 13 on an outstanding set of results. The students have achieved the highest percentage of A* grades in the history of the school.

58% of all grades were A*/A

28% of all grades were A*

82% of all grades were A*/B

18 students achieved 4 A*/A grades, including EPQ and a further 17 achieved 3 A*/A grades.

Each year around a quarter of our Sixth Form students join us in Year 12 from other local secondary schools. Credit is due for the foundation they received at these schools which, in addition to the support at CCHSG, helped them to achieve excellent A level results.

Mrs Marshall said “We are extremely proud of the students and these outstanding results will form a stepping stone to future success. We thank them for the tremendous contribution that they have made to CCHSG and wish them every happiness in the future.” 

Last year, we celebrated the best results in the history of the school; this has once again been repeated. We thank students, staff, governors and parents for all of the hard work and support on our journey.

There were 140 students taking GCSEs in 2019. The school was ranked the fourth state school in the country for GCSE performance in The Times.

Progress 8 Score (provisional) +1.01

Attainment 8 Score (provisional) 82.0

% 9 Grades 46%

% 9-8 Grades 74%

% 9-7 Grades 90%

% of students achieving a strong pass (5+) in English and Maths 100%

% achieving English Baccalaureate (from entries) 100%

% Achieving 5 GCSEs (Grades 9-5) 100%

17 students gained 9/9/9 in English Language, English Literature and Mathematics.

We are proud of all of our students and their efforts. Many congratulations to our Year 11 on such an outstanding set of results and the exciting opportunities that lie ahead.

Newly released provisional figures from the Department for Education for the August 2019 GCSE results, place CCHSG top in Essex, as judged by both the Progress 8 and Attainment 8 measures.  Progress 8 is a measure of the progress that students make from arrival in Year 7 until GCSE results. Based on the student’s best 8 GCSE grades, including English and Maths, if a student makes the progress expected, the school’s Progress 8 score is 0.0.  A score of 0.5 means pupils made on average, half a grade more progress across their subjects than expected.  Our Progress 8 score of 1.01 means that students on average achieved a whole GCSE grade higher than they would have been expected to achieve.  This is particularly pleasing given that students join us already achieving at a high level and provides strong evidence of the value added by the school to the overall academic progress of our students.

Mrs Gillian Marshall, Executive Principal said:  “While we are delighted with the school’s performance in both attainment and progress, the students also deserve to be commended for attributes not reflected in league tables, such as their kindness, support of each other and community spirit.  It is a pleasure and a privilege to work with them and we thank the students themselves, our parents and governors for their consistent support and our hard working and loyal staff who aim high and always want the very best for all our students.”   

CCHSG is one of only 16 grammar schools, across 12 counties in England to have been given a share of the Department for Education's £50m selective school expansion fund. The fund supports the expansion of selective schools that have plans to improve access for students from disadvantaged backgrounds.


We are delighted that our partner school, The Gilberd School, has secured an Outstanding Ofsted judgement at their recent inspection.
