You first need to pause and consider what you want out of all this:  What are your motivations? What are your options? What are your requirements?

Why would you move schools for sixth form?

In our experience, most students fall into one or more of the following categories:

• You’ve been in your current school for a while, and it all feels a bit stale or stifled. You want to freshen things up and start moving on with life.  Both academic and/or personal factors can drive this.

• You have developed specific academic passions and interests. You now want to find a private 6th form school or college which offers a more specialist provision.

• Your current school might not even offer the subjects or curriculum you want. A move is therefore inevitable.

• You want to move from a state school into a private 6th form to benefit from a final boost before university.

• You feel ready to fly the nest and try boarding. You want to meet new people from around the world, focus on the things that matter to you, and develop your independence before you move onto university.

• If you’re coming from overseas, you feel that a couple of years settling into academic and social life in the UK will give you that boost towards the top universities. It could give you the best academic and personal preparation for your future here.

• A change of family circumstances necessitates a move

Take time to have a deep think about your  own academic and personal reasons for moving.

Think of your Future goals

“Begin with the end in mind” they say, and this very much applies to your sixth form education.

The ideal scenario is to think as far ahead as possible, then work backwards to figure out the best path towards your goals. Ask yourself:

• What degree, qualifications, or experience do I need to enter the career I want?

• Which universities and degree courses are particularly good for my chosen career?

• Is it worth looking into professional apprenticeships?

• What entrance requirements do the above have, in terms of curriculum, subjects, and grades?

Thinking about these questions will give you a clearer idea of what curriculum, subjects and grades you are going to need.

I’m not sure what I want to do in sixth form!

Don’t panic if you’re really not sure yet. You’ll be able to make choices that keep your options somewhat open – just do what you can to try to get a vague sense of direction. Seeking careers advice or speaking to someone is a great way to help you reflect. Always get in touch if you want a chat or to be introduced to a qualified Careers Adviser.

It’s really tough on young people to have to make these decisions but, rightly or wrongly, you’ll soon need to make some choices which could close a few doors or start you down a particular path.

So try to take control of your destiny. Be as proactive as you can be, and share your thoughts and ideas with someone who can listen and advise without bias or judgement.

Identify your best curriculum

Curriculum and subject choice are now far more important considerations than when you choose a school at age 4+, 7+, 11+ or 13+: Sixth form is the business end of your school life and the choices you make matter.

A change of curriculum is often the driving factor for many students who switch schools at sixth form. Perhaps you’ve heard about the International Baccalaureate and like the sound of it. Maybe you think BTECs would offer you a better way of learning and a fairer method of assessment? Could an International Foundation Programme offer you a quicker and more affordable pathway to a top British university?

Do not assume that A-levels is the only, or the best, sixth form option. Make sure you have read the Top School Guide curriculums guide in detail, considered BTECs, and done further research as required

Subject choice is crucial

If you really have no idea about what you want to do in future, pick subjects you are strong at and enjoy.

If you’re good at everything, choose a good spread of highly respected subjects, which Russell Group universities used to recognise as Facilitating Subjects. A  mix of Maths, one of the sciences, history, Geography, English Lit and foreign languages will stand you in good stead.

It undoubtedly makes life easier if you do have a good idea of what you want to do: If you have a specific university goal in mind, have a look at which unis are the best at your subjects of interest, and note down their typical entrance requirements.

The following table lists popular university undergraduate degrees, followed by the A-level (or HL IB Diploma) subjects that are typically required.

STEP 1 CHECKLIST

Before you move onto the Step 2, make sure you’ve ticked off the research tasks below by the beginning of April 2026:

• Outline your motivations for moving.

• Understand which curriculum or curriculum mix will suit you best.

• Research the entrance requirements for your potential university degree or other career targets.

• Narrow down your subject choice (this also helps focus your GCSE revision).

This is where the real fun part begins. Essentially, you’re about to go shopping for the most enjoyable and rewarding experience of your life so far!

There’s an overwhelming range of sixth form options in the private sector, and they all have glossy brochures and videos of young people having the time of their lives.

So how do you choose the best private sixth form school or college? Let’s break the process down into 3 logical stages.

i) Map out your key requirements and “nice to haves”

It’s easiest to give you the simple sample table below, which Top School Guide made with a talented Vietnamese student who was coming here for the first time to take A-levels.

Have a look at her requirements for each key consideration:

Now make your own table of key requirements and “nice to haves”. Imagine this next stage of your life and make a wish list. If you can visualise the 6th form you want, it will be a lot easier to find.

Many of your choices will be instantaneous but, if you’re not quite sure about something, read some related articles and bounce some ideas around with someone who has done this before.

If you really love numbers and data, you might also want to consider adapting the above table into a weighted decision matrix. Top School Guide’s Private School Decision Matrix template is free to students and families who apply through this site.

 ii) Identify some best-match schools

You’re starting with around 600 private senior schools in the UK. If you are only looking at local day schools, your options will be limited by geography from the beginning.

To maximise your options, we would always recommend considering boarding at sixth form, providing it’s financially feasible for your family.

The Top School Guide school filter is a great place to enter your key requirements and start window shopping. Each school has a profile with an overview of the facilities and vibe, curriculum details, exam track record, video gallery and tips on how to apply.

It’s free to use and make a shortlist and, when you submit this to us, we’ll get in touch to sense-check your selection We can also suggest alternative schools and guidance on next steps.

iii) Dig deeper

Keep in mind that your goal is to narrow down your options until you find the perfect fit for your academic goals and personal preferences. For that, you need more information.

If you live in the UK, the best idea is to attend an open day. Private sixth form open days usually take place at the start of the summer term, so that is late April in 2026.

If you’re unable to attend open days, then you can:

Investigate school websites

School sites are most useful to investigate your “Nice to have” requirements such as subject specialisation, uni progression, facilities, and the school’s general vibe or personality (pay attention to the Head’s welcome.)

Just keep in mind that each school’s website is a marketing tool – so engage your critical thinking.

Read reviews

It’s rare to read a bad school review, so these don’t genuinely tell you about the quality of a school. For dry, technical overviews, you can use the Independent School Inspectorate, or Ofsted reports. If you do use these reports, then make sure you hear why so many educators believe that such regulatory agencies are not fit for purpose.

Use League Tables

These don’t tell you how good a school is, but can indicate which schools are more academically selective than others. See our separate guide on how to use school league tables for private school sixth form entry.

Speak to people

Current or former parents are usually either in love with the school or holding a vendetta. As we all know, very few parents will ever admit to making a bad decision!

Current students are usually the best people for up to date insight. But keep in mind that what constitutes the “best” private sixth form school or college is very much a personal choice – so what suits them may not suit you.

TSG has visited hundreds of schools, and is always happy to offer frank and impartial opinions to those who ask.

Combine a quantitative and qualitative approach to find the best schools

What you are trying to do is narrow down schools to a small number which best fit your:

• academic aspirations and preferences
  and
• personality

Starting off with a data-driven approach is extremely useful: A school’s exam track record can indicate how competitive it is to get in. Oxbridge progression and subject specific results are also clear signs of a school’s academic success and/or particular focus.

The is an endless amount of data you can gather. Boarding numbers, boarding ratio, 6^th form ratio, class sizes, student demographics, years the Head of Physics has been there, tennis courts, clubs, or trips – all of these can be measured.  So prioritise the things that matter to you and then get gathering.

There are other things which cannot be so readily quantified. How much freedom or responsibility 6^th formers are given, the style of relationships between teachers and students, how separate 6^th form is from the rest of the school, the approach to religion or discipline. Yet these things could have a huge effect on your experience, happiness, and performance.

Your prefrontal cortex won’t be fully matured until you’re around 25 years old. But at age 16, your core character and belief system is fairly well established. You are now far less malleable than an 11 year old, so the environment, ethos and vibe of sixth form will need to suit you if you are to join seamlessly.

There’s a lot to weigh up and balance and, whilst data is hugely useful, there is no exact science to choosing a private 6th form school or college. Use your head and pay attention to your gut.

Once you’ve assessed and narrowed down your target schools, you’ll be ready to move on to STEP 3: Apply For Sixth Form.

STEP 2 CHECKLIST:

Make sure you’ve ticked off the tasks below by the end of June 2026:

• Map out your key requirements and “nice to haves”.

• Identify a long list of possible school matches based on your key requirements.

• Use your “nice to haves” and a process of elimination to narrow down your long list. We recommend getting to:
  – 2 or 3 options for day places
  – 3 to 5 options for boarding

• Remember to question what you read, and ask someone in the know for an unbiased opinion.

You’ve now narrowed down your school choices. If you’re looking for a day place, 2 or 3 should be more than enough, though a lack of choice can often meant here is one clear favourite.

For boarders, we recommend identifying 3-5 favourites, though remember to hedge your bets somewhat (i.e if you only apply to Wellington College, Sevenoaks, or any other highly competitive school, then you risk receiving no offers at all.)

Once you’ve identified which schools are right for you, you need to go about showing them that you are right for them.

Like you, schools will be looking for new students who are the best academic, and the best personal, match. Here’s how to make sure schools understand you are a top sixth form candidate.

5 key stages to making successful sixth form applications to the best private schools.

i) Know the timelines, deadlines and processes.

ii) Get your docs together.

iii) Make a serious approach.

iv) Prepare for assessment.

v) Take your shot.

Let’s look at each stage in a little more depth.

i) Know the timelines and processes

Each school will have its own application deadline and entrance process. The earliest deadline is usually Wycombe Abbey (June 1st!) and, as with many oversubscribed schools, late applications are refused on the principle of consistency and fairness.

Here is an approximate timeline for applications to private school 6^th forms.

June  – September 2026: Registrations

Registration forms and fees (£100-500) must be submitted alongside supporting documents, including any specified pre-tests (usually language or aptitude tests for international students.)

October/November 2026: Entrance Assessments

Entrance tests take place, usually in the subjects you intend to study at A-level or IBDP Higher Level. Most schools will also want to interview students.

Some schools will insist on students coming to the school for entrance assessments, and some even set aside whole days to assess how students work in group tasks etc.

Fortunately, the majority of schools will also allow students to sit sixth form assessments and interviews remotely, providing there is suitable invigilation for exams.

December 2026: Offer Letters

Offers (or notice that an offer will not be made) are usually sent out early December. Most schools request acceptance confirmation within a month, though sometimes it’s as little as 14 days.

As stated, this is a typical, approximate timeline for private schools’ 6^th form applications. Make sure you know the exact timelines and processes for each of your target schools.

ii) Get your documents together

Admissions staff have a lot to deal with, and it’s best if you make their lives as easy as possible.

Get a head start by preparing the following documents electronically, and clearly naming each file. You might not need all of them immediately, but better to prepare them now.

• The past 2 years of schools reports (name and date each report clearly.)

• Any relevant Ed Psych report.

• Any additional pre-tests or assessments.

• Passport page, possibly birth cert.

• Personal statement (sometimes mandatory, ALWAYS beneficial).

iii) Make a serious, tailored approach

Again, try to see it from an Admissions’ point of view: A polite, concise introductory email with the above files attached and request for next steps is fine. We would even recommend a phone call – from parents is fine but from student can be even more impressive.

It’s most important that your approach is tailored to each school. This shows you have done your research and are a serious contender. People who copy and paste the same email to 20+ schools can be spotted a mile off. First impressions count, and you’ll want to appear a serious contender from the get-go.

iv) Prepare for assessment

Parents, in particular, can get really hung up about preparing for entrance tests. We can introduce you to reputable tuition companies if you wish.

But keep in mind that there’s only so much you can do:

• A student averaging B grades for the past 2 years will always struggle to pass the assessments for a school A*-A entrance requirements. No amount of last-minute tuition will change this. Of course aim high but use your time wisely.

• There’s only so much time you can commit to tuition – especially if a lot of it will fall over the summer holidays. You might be better off having a break and just spending a week or two at a subject-relevant summer camp. Work smart, not just hard.

• You’re already entering your final year of GCSEs, so you’ll likely be prepping for a big year. See this as a warm up opportunity, but keep something in the tank for your GCSEs

• Imagine doing just enough to squeeze into a school where you’ll be out of your academic depth: You are setting yourself up for a miserable 2 years.

Instead, we recommend keeping it simple: Get hold of some sample entrance papers, either for the exact schools you are applying to, or to schools of a similar level.

Practise taking these assessments under test conditions. Review your answers, fill in any knowledge gaps, and try honing your timing and technique. Rinse and repeat.

Assessment can include an interview

To prepare for private school sixth form interviews, you need to know your school and know what they are looking for. You’re applying as you’re convinced the school is right for you – and now you have to convince the school that you are right for them.

During interviews, the elite academic schools may ask you questions to assess your subject expertise. But most schools will ask a more personal set of questions to figure out what you are about, what you’d bring to the table, and how well you’d fit in.

Students who apply through Top School Guide are provided with appropriate sample test papers, interview questions, and have the option for a mock interview with feedback.

v) Take your shot

If you are applying for the right schools, then you have as good a chance as anyone. A lot will come down to how you, and the competition, perform on the day. Luck always has a part to play.

All you can do is give it your best shot and keep perspective: If you’re not made an offer from your top choice private school sixth form, then it was probably just not the right fit.

Providing you’ve applied sensibly to an appropriate spread of schools, you will be successful with another application, and it will probably be a better fit for you.

STEP 3 CHECKLIST

Make sure you’ve ticked off theapplication tasks below. This should ideally be by the end of June 2026 as, from this point, windows begin closing until around early November.

• Establish the timelines and processes for each school

• Take time to understand what each school is looking for

• Prepare your documents and make approaches

• Complete the registration paperwork

• Prepare a timetable to practise entrance papers

• Roleplay some mock interviews

The first week of December has come and gone, and you are now in possession of a handful of private school sixth form offer letters – congratulations! You now just have the easiest part left to do.

If you’ve already visited each school, completed your school decision matrix, and developed a “gut feel” for the best-fitting school, then your final decision should be straightforward.

If you still need to, review all of your initial requirements and reassess the weighting of each. There is a good chance that your initial priorities and perspectives will have changed.

Also review how the whole registration process went, and how it made you feel. Your experience can give you some behind-the-mask insight into the real personality of each school.

If you feel the need and have the opportunity to revisit again in person, then do so. Likewise, ask for a final chat (with the head of sixth is always good) about your subject choices, or any other concerns.

Once you are sure, confirm with your favourite school and await their confirmation. Please then inform the schools you are turning down, as this immediately frees up a space elsewhere.

Once you’ve made your final decision, it is time to park it and get on with the rest of Year 11: Your place at your next school (or admission onto particular subjects) will likely be conditional on you achieving certain grades at GCSE.
