16+ Entry to Independent Sixth Forms: How the Process Works

16+ entry to independent sixth forms works through each school's own process, which usually runs from online registration in the year before entry, through written assessments and an interview, to an offer that depends on GCSE results. Students who join at 16+ start Year 12 at a new school and study A-levels or, at schools that offer it, the International Baccalaureate. No single common 16+ test exists, so the admissions page of each school decides every detail.

The Independent Schools Examinations Board (ISEB) sets Common Entrance for 11+ and 13+ entry and Common Pre-Tests for pupils in Year 6 or 7, and its assessments pages mention no 16+ test. Families therefore compare schools one by one, noting the registration route, the papers set, the interview format and the GCSE conditions each school names.

What does 16+ entry mean?

16+ entry means joining a school at the start of Year 12, usually after GCSEs elsewhere, to study A-levels or, where the school offers it, the IB. The Independent Schools Council (ISC) and the Boarding Schools' Association (BSA) both list sixth form among the usual entry points to independent and boarding schools, alongside the earlier ages. Students already at the school normally move up from Year 11, whilst external applicants join them from other schools, so a new Year 12 is often a mix of both. Each school's admissions page names the courses it offers.

What are the usual stages of 16+ entry?

The usual stages are registration, assessment, interview, a reference from the current school, a conditional offer and confirmation once GCSE results arrive. The order differs between schools: Westminster School writes to the head of the candidate's current school before interviews, North London Collegiate School (NLCS) asks for a reference and GCSE predictions before it calls candidates to interview, and Shrewsbury School requests a reference from the current headteacher alongside its assessments.

Offers are conditional, and the school's page names the GCSE conditions that apply, which sometimes vary by subject. Acceptance is then confirmed in the way the school sets out, for example in writing or on a returned form.

• Registration: usually an online form, completed before a candidate can sit the school's assessments
• Assessment: school-set papers or an assessment day, often linked to the subjects the student plans to study
• Interview: often for shortlisted candidates, with a senior member of staff
• Reference and reports: from the current school, sometimes with predicted grades or mock results
• Conditional offer: dependent on GCSE results
• Confirmation: after GCSE results, following the school's acceptance steps

Is there a common 16+ entrance test?

No common 16+ entrance test exists, and each school sets its own papers. ISEB's assessments pages list Common Entrance at 11+ and 13+ and Common Pre-Tests for Year 6 or 7, with no 16+ test. At Westminster, candidates choose A-level subjects and sit papers in them, whilst NLCS tests students in the subjects they plan to study, based on the common core of GCSE syllabuses.

ISC states that schools without Common Entrance normally ask applicants to sit tests in English, maths and possibly other subjects, and to attend an interview. International applicants may meet UKiset, an adaptive assessment developed with Cambridge University Press & Assessment; its page does not state which year groups it covers, so a family should ask each school whether it accepts a UKiset Profile for sixth form entry.

How does 16+ entry differ from 11+ and 13+ entry?

At 16+ the student is the main candidate, and schools judge the application on subject-based papers, an interview, reports and a reference, with GCSE results deciding the final offer. Entry at 11+ and 13+ more often draws on shared ISEB assessments such as Common Pre-Tests and Common Entrance, which the ISEB site describes for those ages.

Subject choice also arrives earlier in the process. Applicants usually name the A-level or IB subjects they want when they register or sit papers, and the offer can carry grade conditions in those subjects. A tutor can help the student practise and prepare for the papers and interview that the school describes on its page.

Are internal and external applicants treated differently?

It depends on the school, and several admissions pages describe one process for everyone. Westminster states that all applications are treated in exactly the same way, and NLCS describes external entrants joining pupils who come up from its own Year 11, with the same entrance tests for all registered students.

A student already at an independent school with its own sixth form can ask the admissions or sixth-form office whether progression from Year 11 is automatic or depends on GCSE results, since that answer is set by the school and not by any shared rule.

Can a student board or attend as a day pupil at 16+?

Many schools offer both day and boarding places at 16+, and the BSA lists sixth form among the typical boarding entry points. The BSA states that there is no central clearing system for boarding schools, so families contact each school directly and check that a boarding place is available for the start date they want. Its advice is to apply in the autumn of the year before entry.

Some schools ask for the choice early: Westminster requires the boarding or day decision before registration and describes its boarding as weekly and term-time. ISC's school search can filter by day or boarding, and each school's page explains its own arrangements.

The BSA suggests that overseas families arrange a UK guardian for their child. Visa routes depend on age and circumstances, so the Student visa and Child Student visa pages on gov.uk are the place to check eligibility, alongside the school's international admissions team.

What does a work-back plan for 16+ entry look like?

A work-back plan starts from the GCSE results stage and moves backwards through each stage the school describes, ending with research in Year 10. ISC notes that registration timing varies by school and that some schools ask for applications well ahead, so each admissions page sets the real sequence. Scholarship routes have their own steps, covered in our sixth-form scholarships guide.

Working from the end, a family usually fixes the following stages in turn:

• GCSE results: check the grade conditions in the offer and the school's confirmation steps
• Conditional offer: note the acceptance steps and any boarding or house arrangements
• Interview: practise talking about chosen subjects and wider interests
• Assessment: find out the format and subjects, then practise the papers
• Reference and reports: ask the current school early, so predictions and reports are ready
• Registration: complete the school's online form, ahead of its assessments
• Year 10 research: visit schools, compare courses and shortlist

11+ and entrance exam preparation with Taylor Tuition

Families weighing up independent schools usually need a child ready for the school's own entrance assessment at 11+ or 13+, whatever the fee or bursary position, and that is where our programmes start. Having prepared pupils for entry to leading independent and grammar schools, with placements including Westminster, St Paul's, Wycombe Abbey and Eton, our tutors plan the work backwards from each school's assessment format and registration deadline.
