What says..

Historically, the school has been criticised as being an elitist, academic hothouse, but there is overwhelming agreement that is no longer true, with staff being pushy, but by not overly so. There’s a sense that you can be who you really are at this school. ‘There’s room for every type of person,’ confirmed one student. Parents agree. ‘Whether you’re in the nerdy academic bunch, the sporty lot or the performing arts bunch – or in no particular bunch at all - you are seen as equal,’ said one. Evidence of an ordered and respectful…

What the school says...

After 12 years as Deputy Headteacher, Kay Mountfield was appointed permanent Headteacher in April 2018. Passionate about education in its widest sense Kay advocates a rich curriculum that excites and extends all learners alongside a wide range of cultural, creative and sporting opportunities. She is proud of the mutually respectful culture at the school where teachers and pupils share a passion for their subjects and can readily express an enthusiasm for learning and where so many young people recognise their responsibility for the wider and global community. As Headteacher she tries to keep in touch with the students as individuals, meeting with all Year 7 for tea, and helping direct school musical productions. ...Read more

Please note: Independent schools frequently offer IGCSEs or other qualifications alongside or as an alternative to GCSE. The DfE does not record performance data for these exams so independent school GCSE data is frequently misleading; parents should check the results with the schools.

Special Education Needs

Special Needs issues are addressed in the first instance within the classroom context. Additional support and advice is provided by members of the Leadership Team, with each of the three Assistant Heads taking a specific interest for one Key Stage. The Assistant Heads are also supported by Heads of Key Stage 3 and 4 and by full time Learning Mentors, each of whom works with a single year group, following them through their school careers. Screening for specific issues, such as dyslexia, is undertaken on intake in Year 7. The school also works closely with the Local Authority's SEN support services, including an attached Educational Psychologist.

Interpreting catchment maps

The maps show in colour where the pupils at a school came from*. Red = most pupils to Blue = fewest.

Where the map is not coloured we have no record in the previous three years of any pupils being admitted from that location based on the options chosen.

For help and explanation of our catchment maps see: Catchment maps explained

Further reading

If there are more applicants to a school than it has places for, who gets in is determined by which applicants best fulfil the admissions criteria.

Admissions criteria are often complicated, and may change from year to year. The best source of information is usually the relevant local authority website, but once you have set your sights on a school it is a good idea to ask them how they see things panning out for the year that you are interested in.

Many schools admit children based on distance from the school or a fixed catchment area. For such schools, the cut-off distance will vary from year to year, especially if the school give priority to siblings, and the pattern will be of a central core with outliers (who will mostly be siblings). Schools that admit on the basis of academic or religious selection will have a much more scattered pattern.

*The coloured areas outlined in black are Census Output Areas. These are made up of a group of neighbouring postcodes, which accounts for their odd shapes. These provide an indication, but not a precise map, of the school’s catchment: always refer to local authority and school websites for precise information.

The 'hotter' the colour the more children have been admitted.
