History & Ethos

Our reputation for academic excellence stretches back over three decades – with the past few years in particular seeing success after success.

Our Ethos

Charterhouse Square School has a character and ethos all of its own. Perhaps it’s something to do with our central location or the surprising space and colour we enjoy across our two neighbouring buildings. Perhaps it’s that our children don’t wear a school uniform and that they stay together with the same classmates all the way through school from entry at nursery. Or perhaps it’s something to do with the happy atmosphere around the place – where it’s not unusual for our teachers to stay in post for well over a decade, and for our girls and boys to come back for a visit long after they have left the school.

These are characteristics that combine to make the school a special place. We are known for our academic success – and that is a source of great pride to us – but we care more about the safe, nurturing environment that makes this success possible. That’s why we place so much emphasis on schemes such as our ‘buddy’ system, for example, which sees each new girl and boy paired up with one of the pupils from the top of the school. And it explains why we are all – pupils and teachers – known by our first names: it makes the teachers so much more approachable and creates that all-important home-from-home feel.

We also aim to cultivate the right blend of social skills and confidence in our boys and girls. After all, which of us hasn’t encountered the power of confidence in our school and working lives? We believe that it is this quality – coupled with the high expectations we have of our children – that explains the consistent success of our older children in the exam room and readies them for further success in their future academic careers.


Our History

1985

Charterhouse Square School is founded by original headmistress Jamie Mason with school fees set at £425 per term! Over the course of the next two decades we go on to gain a reputation for all-round academic performance.

2008

In March the school becomes part of Cognita – a worldwide group of schools founded by Sir Chris Woodhead, former head of Ofsted. In December Caroline Lloyd takes over as Headmistress fifteen years after first joining the school. Remarkably she is only the second head in the school’s history.

2009

When space becomes available in an adjacent building, the school expands to occupy a total of seven floors in our much-coveted Barbican location. This allows the school to add a dedicated Early Years area, a school library and an art room.

2012

The school is graded ‘outstanding’ by Ofsted in all seven areas assessed.

2014

In further work to improve the school site, the entire basement and ground floor of number 40 is completely remodelled. The addition of bi-folding glass doors to link our Green Room to its outdoor sand and water area is a particular hit with the children.

2015

Charterhouse Square School celebrates its 30-year anniversary with a surprise party for the children and a ball for parents, teachers and friends of the school. The school is also featured in The Good Schools Guide for the first time.

2016

The school is once more judged to be outstanding in all areas – this time in a report by the School Inspectorate Service. We are also delighted to welcome an application from a parent who once attended the school as a pupil – a trend that we hope to see continue as the school moves forward into its fourth decade.
