If you’re currently researching independent schools for your child’s secondary education, you may have come across the phrase ‘diamond school’. But what is a diamond school, and what are its benefits for your child?

What is a diamond school?

A diamond school follows a unique model of teaching in which boys and girls are taught separately for some subjects, or entire year groups, at co-educational schools. The most common use of this model includes co-education until the age of 11 and from ages 16 to 18, but single-sex teaching in-between for Key Stages 3 and 4 (Years 7–11).

The diamond model was developed by New Hall School in Essex – a move which resulted in it being awarded the Independent Schools Award for Outstanding Strategic Initiative in 2011. It was the first independent girls’ school – and the only Catholic school – to implement the diamond model of co-education.

15 UK independent schools have since adopted the diamond model – we’ve included a full list below.

What are the benefits of diamond schools?

The purpose of the diamond model is to give pupils the benefits of both co-ed and single-sex education.

The diamond model allows schools to sensitively tailor their pastoral care and academic provision to young people. While co-education is more reflective of real life, many schools argue that there are academic benefits to single sex teaching as young teenagers are more focused when taught separately.

As they become young adults, pupils have to deal with the physical and social upheaval – and in some cases, negative peer pressure – that comes from all the major changes of adolescence. Many believe that single-sex schools are better equipped to support young people through these crucial years.

However, there are plenty of benefits that come from co-education beyond the classroom – which is why most diamond schools have shared extracurricular facilities and programmes. Pupils mix for team sports, music, drama, and activities such as the Duke of Edinburgh Award and CCF, which contributes to a healthy team spirit and a natural overall community ethos.

Meanwhile, the diamond model can suit parents with both sons and daughters. Most diamond schools teach all their pupils on one site (or at a minimum, the senior boys’ and girls’ schools are located close to each other). This makes the logistics of the school drop-off and attending school events easy for busy families who want the benefits of single sex education.
