Grammar School vs Private School: A Parent’s Guide

Choosing a secondary school for your child is one of the biggest decisions you will ever make as a parent. You want the best for them. You want them to thrive, make friends, grow in confidence, and walk into their future with the best possible start.

In the UK, two school types come up again and again in parent conversations: grammar schools and private schools. Both are known for strong academic results. Both attract ambitious families. But they are very different in how they work, who they are for, and what they cost.

This guide breaks it all down for you, simply and honestly. By the end, you will know exactly what sets these schools apart so you can make the right choice for your child.

What is a Grammar School?

A grammar school is a state-funded secondary school that selects its pupils based on academic ability. That means grammar schools are free to attend. No tuition fees. No monthly bills. The government pays for them.

The way children get into a grammar school is through the 11+ exam (also called the eleven plus). Children usually sit this exam in Year 6, when they are around 10 or 11 years old. The test measures skills in areas like English, Maths, verbal reasoning, and non-verbal reasoning.

If your child passes the 11+, they can apply for a grammar school place. If they do not pass, the grammar school route is generally closed to them.

Grammar schools have a long history in England. While many were converted into comprehensive schools over the decades, around 163 grammar schools still operate across certain areas of England, particularly in counties like Essex, Kent, Buckinghamshire, and Lincolnshire.

One important thing to know: grammar schools are not available everywhere in the UK. If you live in an area without grammar schools, this option simply may not be on the table for your family.

What is a Private School?

A private school, often called an independent school, is funded entirely through the fees that parents pay. The government does not fund private schools. This means they operate independently and can set their own curriculum, teaching style, and admissions criteria.

Private schools come in many forms: day schools, boarding schools, preparatory schools (prep schools for younger children), and all-through schools that take children from early years right up to sixth form.

Because private schools rely on fees rather than government funding, they have more freedom to invest in resources, facilities, and smaller class sizes. Many are renowned for their sports facilities, arts programmes, and university preparation support.

Unlike grammar schools, private schools are available across the whole country. And while many do have their own entrance exams or assessments, the admissions process is generally more flexible than the grammar school route.

Grammar Schools vs Private Schools: The Key Differences

Here is a clear, side-by-side look at how grammar schools and private schools compare across the things that matter most to parents.

1. Cost

This is often the first thing parents want to know.

Grammar schools are free. As state-funded schools, they charge no tuition fees. There may be some extra costs for trips, uniforms, or optional activities, but the core education costs nothing.

Private schools charge fees. These fees can vary enormously depending on the school, its location, and whether your child is a day pupil or boarder. Fees at the most prestigious schools can be very significant indeed. Some private schools offer scholarships for academically gifted children, and bursaries for families who cannot afford full fees. But for most families, private school is a substantial ongoing financial commitment.

For families where cost is a key factor, grammar school represents exceptional value. The academic outcomes can be comparable to schools charging very high annual fees.

2. Admissions

Grammar schools select pupils almost entirely through the 11+ exam. Pass the exam, and your child can apply. The process is straightforward, but highly competitive. In areas like Essex, the demand for grammar school places far exceeds supply.

Private schools have more varied admissions processes. Many have their own entrance exams, often at ages 7, 11, or 13. They may also consider interviews, school reports, and references. Some private schools are selective; others are not. The admissions criteria differ from school to school.

3. Class Sizes

Private schools are well known for their smaller class sizes. Fewer pupils per teacher means more individual attention, more personalised feedback, and a teaching style that can be adapted to each child's needs.

Grammar schools, while selective and academically focused, tend to have class sizes more similar to standard state schools. They are not as large as a typical comprehensive school, but they do not match the small classes common in the private sector.

4. Facilities and Resources

Private schools often invest heavily in state-of-the-art facilities. Think science labs, performing arts centres, swimming pools, sports fields, and technology suites. The fees they collect are reinvested directly into the school environment.

Grammar schools are funded through the state system, which means their resources are comparable to a standard school budget. That said, many grammar schools still offer excellent facilities and a rich range of extracurricular activities.

5. Academic Results

Both types of school are associated with strong academic outcomes, and this is not a coincidence. Grammar schools select the most academically able pupils. Private schools invest heavily in teaching quality and support.

Top grammar schools regularly feature in national league tables alongside, and sometimes above, some of the most well-known private schools. The key point here is that results at both types of school tend to be strong, but the pathways to those results differ.

6. University Destinations

Both grammar schools and private schools send students to leading universities, including Oxford and Cambridge. Private schools often have dedicated university counsellors, Oxbridge preparation programmes, and personal statement support built into the school experience. Grammar schools also produce strong university applicants, and many grammar school students compete successfully for the most selective courses and institutions.

7. Extracurricular Activities

Private schools typically offer a very wide range of extracurricular opportunities: music, drama, sports, debating, Duke of Edinburgh, coding clubs, and more. With greater resources, they can offer specialist coaching and dedicated facilities.

Grammar schools also offer extracurricular activities, though the range may be narrower. Many grammar schools have excellent sports teams, music programmes, and enrichment activities, but it varies by school.

8. Social Mix

Both grammar schools and private schools tend to be less socially diverse than a typical comprehensive school.

Grammar schools are theoretically open to any child who passes the 11+, regardless of background. However, in practice, children whose families can afford 11+ tuition are statistically more likely to pass. This means that while grammar schools are free to attend, access is not entirely equal.

Private schools, by definition, are limited to families who can pay the fees. Some offer genuine access through bursary programmes, but the majority of pupils come from more affluent backgrounds.

Grammar School vs Private School: Which is Right for Your Child?

There is no single right answer to this question. Every child is different. Every family is different. Here are some honest questions to help you think it through.

Is your child academically very strong?

If yes, a grammar school could be a brilliant, cost-free option that puts them alongside equally able peers.

How does your child handle exam pressure?

The 11+ is a high-stakes test. Some children rise to that kind of challenge. Others find it deeply stressful. If your child is talented but does not perform well under exam pressure, a private school route may suit them better.

What are your financial circumstances?

Grammar school removes the financial burden entirely. If stretching to cover private school fees for seven years would create real stress in your household, that matters. Financial pressure in the home affects children, too.

What does your child value? 

If they are passionate about a particular sport, instrument, or art form, a well-resourced private school may offer specialist opportunities that make a genuine difference to their development and happiness.

Are grammar schools available where you live?

If you are not in a grammar school area, this comparison may be largely academic. Private school may be your primary option if you want a selective education for your child.

What does your child want?

Children, especially as they get older, should have a real say in something this significant. A child who feels forced into a school rarely thrives.

How to Prepare Your Child for the 11+

If the grammar school route appeals to your family, preparation is key. The 11+ is a competitive exam, and children who prepare thoroughly are far more likely to succeed. Here are some of the most effective ways to help your child get ready.

1. Start Early

The earlier you begin, the less pressure your child will feel as the exam approaches. Starting in Year 4 or early Year 5 gives your child time to build skills gradually rather than cramming at the last minute. A little practice done regularly beats a lot of practice done in a panic.

2. Work on the Core Skills

The 11+ tests English, Maths, verbal reasoning, and non-verbal reasoning. Make sure your child is comfortable with each of these areas. Reading widely every day is one of the single best things a child can do to improve their English and vocabulary naturally.

3. Use Practice Papers Regularly

Sitting practice papers is one of the most effective ways to prepare. They help your child get used to the question types, the layout of the paper, and the time pressure of the real exam. We offer free 11+ practice papers that you can download and use at home right away, at no cost.

4. Get Expert Support

Many children benefit enormously from working with an experienced tutor who knows exactly what the exam demands. A good tutor does not just drill questions; they identify the specific gaps holding your child back and fix them. Our 11+ tutors work with each child individually, building both their ability and their confidence in a way that generic revision simply cannot match.

5. Make the Most of the Summer

The summer before the exam is a golden window of opportunity. Children have time, fewer distractions, and the exam is close enough to make focused preparation count. Our 11+ summer courses are designed specifically for this period. They are structured, enjoyable, and give children a real boost heading into the final stretch of preparation.

6. Sit a Mock Exam Before the Real Thing

One of the most valuable things your child can do is sit a full mock exam under realistic conditions before the actual test day. It takes away the fear of the unknown, helps them manage their time, and shows you and your child exactly where they stand. Our 11+ mock exams replicate the real exam experience as closely as possible, so your child walks into the test feeling calm, prepared, and ready.

Final Thoughts

Grammar school vs private school is not a question with one right answer. They are two genuinely different types of school, with different costs, different admissions processes and different strengths. Neither is automatically better than the other.

What matters is finding the right environment for your specific child, one where they will be happy, challenged and supported to be their best. For many families, a grammar school place offers outstanding academic education at no cost. For others, the smaller class sizes, broader curriculum and individual attention of a private school make the fees worthwhile.
