Why families choose UK private schools: Academic results, class sizes & co-curricular activities
School Scout 10 min read
Choosing a school is one of the most significant decisions a family will make. Whether your child is preparing to start at pre-prep, moving into Year 7 or considering sixth form, the right school can shape not only their academic journey, but also their confidence, friendships and wider interests.
For many families, an independent school offers far more than strong examination results. Smaller class sizes, extensive co-curricular opportunities, strong pastoral care and a greater degree of educational flexibility are among the reasons parents choose private education.
That said, there is no such thing as the "best" private school. Every child is different, and the school where one pupil flourishes may not be the right fit for another. Understanding what independent schools typically offer can help you decide which qualities matter most for your family.

Both independent and state schools include excellent examples, and many children thrive in each sector. The right choice depends on your child's personality, interests and learning style, as well as your family's priorities. The comparison below highlights some of the characteristics commonly associated with UK independent schools to help you understand the differences.
Smaller School Communities and Individual Attention
One of the defining characteristics of many independent schools is their size. Compared with most state schools, they often educate fewer pupils, creating close-knit communities where children are well known by teachers and staff.
According to the ISC Census and Annual Report 2026, most ISC schools remain relatively small. The median school has 246 pupils, and more than half have fewer than 250 pupils. By contrast, just 6.6% educate more than 1,000 pupils.
School size also varies considerably by type. Junior schools have a median of 195 pupils, compared with 304 pupils at senior schools and 387 pupils at mixed-age schools. Across the 1,455 schools included in the Census, the largest concentration falls within the 100 to 200 pupil range.
Smaller communities can create an environment where pupils build relationships across year groups, participate in a wide range of activities and feel a stronger sense of belonging. Teachers often know pupils beyond the classroom, helping them recognise individual strengths, interests and areas where additional support may be beneficial.
When visiting schools, it is worth asking not only about pupil numbers, but also how the school helps every child feel known and supported.
Individual Attention Through Smaller Class Sizes
For many parents, one of the greatest attractions of independent education is the opportunity for more personalised teaching.
The average pupil-to-teacher ratio at ISC schools is 8.5 pupils for every teacher, compared with 18.0 pupils per teacher across state-funded schools (ISC Census and Annual Report 2026). While pupil-to-teacher ratios are not the same as class sizes, they provide a useful indication of the level of teaching resource available to support pupils.
Class sizes vary considerably between schools, year groups and subjects. Rather than focusing solely on headline figures, parents should ask how teaching is organised, whether pupils are grouped by ability where appropriate, and how children receive additional support or greater challenge when needed.
Academic Results and Broader Measures of Success
Independent schools have a long-standing reputation for academic excellence, with many achieving strong examination results and preparing pupils for leading universities in the UK and overseas.
The ISC Census and Annual Report 2026 highlights the strong progression of pupils leaving ISC schools:
90.1% of post-18 leavers continued into higher education, including university and other higher education courses.
Of those progressing to UK universities, 53% attended a university ranked within the UK’s top 25, including approximately 4% progressing to Oxford or Cambridge.
A further 24% attended universities ranked between 26 and 50.
5.7% chose to study at a university outside the UK.
The United States remained the most popular overseas destination, attracting 48.1% of those attending non-UK universities.
2.4% of leavers entered employment directly.
2.0% entered further education or training, including apprenticeships.
Academic attainment also remains strong. Department for Education data included in the report show that independent school pupils achieved a higher proportion of A* and A grades than pupils in state-funded schools across every A-level subject analysed. In mathematics, for example, 59.0% of independent school entries achieved A* or A, compared with 38.8% in state-funded schools. In chemistry, the corresponding figures were 52.9% and 29.4%.
While these figures demonstrate strong academic outcomes, examination results and university destinations are only two measures of a school’s success.
Parents should also consider how effectively a school helps pupils fulfil their individual potential. For one child, success may mean securing a place at a leading university; for another, it may involve developing confidence, creativity and resilience, or discovering a lasting passion for music, sport or the arts.
The strongest schools recognise that achievement looks different for every pupil.
A Broader and More Flexible Curriculum
Independent schools are not required to follow the National Curriculum in the same way as maintained schools. This gives them greater flexibility to design programmes that reflect their educational philosophy and the interests of their pupils.
Many independent schools also provide opportunities to study subjects and qualifications that may not be widely available elsewhere, including:
Latin, Greek or Mandarin
Philosophy, Politics or History of Art
Extended Project Qualifications (EPQs)
Coding, robotics and digital technologies
LAMDA, debating and public speaking
Many schools also integrate leadership, entrepreneurship, outdoor education and global citizenship into their curriculum, helping pupils develop skills that extend beyond examination success.
When comparing schools, consider not only which subjects are available, but also how the curriculum reflects the school's values and approach to education.
Exceptional Facilities That Enrich School Life
Independent schools often invest significantly in their campuses and facilities, creating environments that support both academic learning and wider personal development. The scale and quality of facilities naturally varies between schools, but many provide specialist learning environments that support both academic study and co-curricular life.
Facilities commonly include:
Modern science laboratories
Design technology workshops
Digital media suites
Theatres, music schools and dance studios
Libraries and dedicated sixth form study centres
Sports halls, swimming pools and all-weather pitches
These resources enable schools to offer an extensive programme of co-curricular activities that can become a defining part of a child's education.
Music, drama, debating competitions, coding clubs, Duke of Edinburgh's Award, outdoor pursuits, community volunteering and creative arts all contribute to developing confidence, teamwork and independence.
The quality of facilities matters not because they look impressive on an open day, but because they expand the opportunities available to pupils every week.
Sport and Co-Curricular Opportunities
Sport plays an important role in many independent schools, although the emphasis varies considerably between schools and individual pupils.
Participation encourages resilience, leadership, teamwork and self-confidence, while helping pupils develop healthy habits that often continue into adult life.
Many schools offer:
Specialist sports coaching
Competitive fixtures
Recreational sport for all abilities
Cricket, rugby, hockey, football, netball and athletics
Swimming, rowing, tennis, golf and equestrian activities at some schools
Equally important are the many non-sporting activities available. Whether a child enjoys orchestra, theatre, photography, environmental projects or robotics, the breadth of opportunities often allows every pupil to discover interests that may remain with them for life.
Pastoral Care and Wellbeing
Increasingly, parents identify pastoral care as one of the most important factors when choosing a school.
Academic success is most likely when children feel safe, supported and confident, and independent schools typically invest heavily in structures that promote wellbeing.
These often include:
Tutor systems or house structures
Dedicated pastoral leaders
School counsellors and wellbeing coordinators
Health centres or on-site nursing provision
Programmes focused on resilience, emotional literacy and mental wellbein
During school visits, ask pupils how well they know their teachers and whether they feel comfortable seeking help when needed. The answers often provide valuable insight into the school's culture.
Lifelong Friendships and Professional Networks
Independent schools frequently develop strong alumni communities that continue long after pupils leave.
Former pupils often remain connected through reunions, mentoring programmes and networking opportunities, providing younger generations with access to advice, work experience and career guidance across a wide range of professions.
While these networks should never be the primary reason for choosing a school, they can become a valuable lifelong benefit.
Choosing the Right School for Your Child
The advantages of private education are well established, but no two independent schools are alike.
Some schools are highly academic and selective. Others prioritise creativity, sport, performing arts, outdoor education or specialist learning support. Some are large and bustling; others are deliberately small and family-oriented. There is no single definition of the 'best' school. The best school is the one where your child will be happiest, most engaged and able to fulfil their potential.
The most important question is not whether one school ranks above another, but where your child is most likely to feel happy, supported and inspired to achieve their potential.
Visiting schools, speaking with teachers and pupils, and comparing different options will often tell you far more than league tables alone.
Frequently Asked Questions
