The Pros and Cons of Selective Schools: What Parents Need to Know

The debate around selective schools—whether grammar schools or independent schools with entrance exams—is a long-standing one. Some view them as engines of social mobility, providing a rigorous academic environment for the most able students. Others argue they create divisions in the education system, reinforcing existing inequalities.

If you're considering a selective school for your child, it's important to weigh both the advantages and the potential downsides.

Before going into the pros and cons, I want to start by giving an analogy.

Imagine there are two hospitals in the local area. Hospital A publishes fantastic results. Almost everyone who is admitted comes out cured. On social media, the hospital receives glowing reviews.

Hospital B, on the other hand, looks quite poor in comparison. The results are average and while some patients come out cured, others do not make a recovery. The forums are mixed about this hospital.

With these outputs, it is easy to make the following conclusions:

Hospital A is better

Hospital A will cure my illness

Hospital A has the best doctors

I really don’t want to go to Hospital B!

However, if we look at the inputs, our opinions may change.

Hospital A has strict admissions criteria. It is only available to people under 45, who have never smoked or touched alcohol and have no family history of complex illness. Each year, patients on roll have to run a marathon in under 3 hours. If you do not pass these tests, you are not allowed treatment.

Hospital B, on the other hand, has no barrier to entry. Anyone can attend - in fact, all in the local community are encouraged to attend. There is no criteria to stay in this hospital - all patients are treated, no matter how trivial or serious.

Do you draw the same conclusions? Is Hospital A really the better one? Does Hospital A have the best doctors? Which one do you want to attend now?

I will leave you to transfer the analogy to the school system… however, please do keep this in mind when you hear a selective school talk about strong exam performance... If the school only accepts children who have proven they are good passing tests, shouldn't strong exam results be a given?

✅ The Pros of Selective Schools

1️⃣ Strong Academic Focus

Selective schools often set high academic expectations, with a long tradition which sets a culture of achievement for students. Smaller class sizes (although, not backed-up by research) might enable more in-depth discussions.

2️⃣ High-Achieving Peer Group

Being surrounded by motivated and academically able peers can create a positive learning culture. This can be inspiring for some students, driving them to work harder and aim higher.

3️⃣ Excellent University Pathways

Many selective schools have strong records of sending students to top universities, with structured guidance on applications, entrance exams, and interview preparation. Some also have strong alumni networks, which can open doors to future opportunities.

4️⃣ Specialist Subjects and Extracurricular Opportunities

With better funding and resources, selective schools often offer a broad range of subjects, including Latin, philosophy, and multiple foreign languages. They may also have extensive extracurricular activities such as debating societies, orchestras, and competitive sports teams. In my opinion, the extra-curricular offer of independent schools in particular is what really stands out compared to the state sector.

5️⃣ Strong Behaviour and Work Ethic

Selective schools often maintain strict behaviour policies and cultivate a disciplined academic environment. This can be a positive factor for children who thrive in structured settings.

⚠️ The Cons of Selective Schools

1️⃣ Pressure and Mental Health Concerns

The high expectations of selective schools can lead to intense pressure, with some students feeling overwhelmed by academic demands. The competition can sometimes lead to stress, anxiety, or burnout. I once spoke to a leader at Eton who told me that whilst we often read about the success stories, there are many students who do not succeed in such a high pressure environment.

Selective schools can also contribute to the development of a 'fixed mindset' (you can read more about this here). In a nutshell, after passing a test, it can be easy for the young person to come to the conclusion that they are 'intelligent' - if they believe this 'intelligence' to be a 'fixed state' (ie. I have passed a test which demonstrates I am intelligent), it can lead to students being unwilling to put in effort (why should I? I am naturally clever.), unwilling to take risks (what if it goes wrong? Does that mean I was wrong about my intelligence?) and less likely to see mistakes, challenge and struggle as growth opportunities. Of course, this mindset can be fostered in all settings, but the specific nature of a test of entry can enhance this.

2️⃣ Narrow Socioeconomic and Social Mix

Despite some efforts to widen access, selective schools tend to have lower proportions of students from disadvantaged backgrounds. The high cost of private tutoring for entrance exams, the ability to afford independent schools, and the cultural capital associated with academic success can create barriers to entry. If you view the purpose of school as preparing students to thrive in the modern world, having only experienced a narrow cross-section of society might mean they are less able to navigate relationships in the future.

3️⃣ Focus on Academics Over Wellbeing

While some selective schools prioritise student wellbeing, others may have a strong emphasis on results, with less flexibility for students who struggle. If a child is not coping academically, they may feel unsupported or out of place. At a crunch, is a selective school going to support a child with their wellbeing OVER the chance of maintaining a strong academic record?

4️⃣ Less Exposure to a Range of Abilities

One argument against selective education is that students benefit from being in mixed-ability settings, where they develop skills such as empathy, leadership, and teamwork. A narrow academic focus may not fully prepare them for the diverse workplaces and communities they will later enter. Some research would suggest that the more 'academically able' pupils will achieve just as well in a mixed setting, but their presence in a mixed class 'pulls-up' the other students.

5️⃣ Uncertainty at the 11+ Stage

For grammar schools, the entrance exam process (often taken at age 10 or 11) can be stressful, with an outcome that might feel like a life-defining moment. A child who just misses the pass mark may feel like they’ve 'failed', even though their potential is unchanged. This again links to the 'mindset' point earlier - if a child believes intelligence is something someone either has or doesn't, if they then fail, will they be telling themselves that they are not an intelligent person?

So, Should You Choose a Selective School?

Ultimately, the right decision depends on your context and your values set. Some children thrive in competitive environments, while others do better in a setting where academic pressure is balanced with broader developmental goals.

Before making a decision, consider: 

✅ Is your child self-motivated and able to handle academic pressure? 

✅ What are the school’s pastoral care policies? 

✅ Are there good alternatives if your child doesn’t enjoy the selective environment? 

✅ How does the school’s culture align with your family values?

There is no one-size-fits-all answer. The most important factor in a child’s success is not simply the school they attend but the support, encouragement, and opportunities they receive at home. The home background of a child is a bigger determiner of future success than a school.
