Applying for sixth form is one of the first genuinely adult admin tasks most students do. It happens during Year 11 while you are also revising for GCSEs, and the timeline sneaks up on people. This guide walks through when to apply, what each stage involves, and how many places to aim for. If you are still deciding between staying on at school or moving to college, our sixth form vs college comparison is a good place to start.
The most important thing to know up front: There is no single national application system for sixth form, the way UCAS handles university applications. Every sixth form runs its own admissions process, with its own form and its own deadlines. That means it is on you to keep track of them.

The typical timeline
Deadlines vary from one sixth form to another, but the general shape of the year looks like this. Always check the specific dates for each place you are applying to, since they can differ by a few weeks.
| When | What happens |
|---|---|
| September to October (Y11) | Open evenings and taster days at most sixth forms. Attend as many as you can before applying. |
| October to November (Y11) | External applications open for most sixth forms. Some deadlines are as early as late November. |
| November to January (Y11) | Most application deadlines fall in this window. Internal applicants (staying at the same school) often have a slightly later deadline. |
| January to March (Y11) | Interviews or subject discussions at more selective sixth forms. Conditional offers start being made. |
| March to May (Y11) | Most students have accepted a conditional offer by now. Time to focus fully on GCSE revision. |
| Late June (Y11) | GCSEs finish. |
| Third Thursday of August | GCSE results day. Offers are confirmed based on grades achieved. |
| Late August to early September | Enrolment days at the sixth form or college. Final subject choices are confirmed. |
If you are staying at your existing school's sixth form, the internal application process is often simpler and the deadline can be later. That said, do not assume a place is automatic just because you are already there; you still need to complete the form.
Step 1: Research your options
Before you start filling in forms, get clear on which sixth forms are realistic options. Look at three things: The qualifications each one offers (some subjects like Government and Politics, Photography, or specific languages are only available in a handful of places locally), your predicted grades relative to their entry requirements, and travel time from home. Sixth form is five days a week for two years, so a long commute is not sustainable. If you are unclear on what "sixth form" actually covers before you start comparing, our guide to what sixth form is is worth a read first.
Step 2: Attend open evenings and taster days
Open evenings typically run in September and October of Year 11, and some sixth forms also offer taster days where you sit in on sample lessons. Websites will not show you what the corridors feel like or how staff talk to students, so going in person matters. Try to speak to current Year 12 students, not just the teachers.
Bring a list of questions. Useful ones include: How are Year 12 mocks structured? What happens if I want to change subjects in October? How much UCAS support do you offer in Year 13? How is enrichment (societies, sport, EPQ) organised?
Step 3: Understand entry requirements
Every sixth form sets its own entry requirements, and they typically fall into two parts.
The first is a general GCSE requirement. Something like "five GCSEs at grade 4 or above, including English and Maths" is common. More selective sixth forms often ask for five or more GCSEs at grade 6, and highly selective sixth forms may ask for a majority at grade 7 and above.
The second is subject-specific. For each A-Level, there is usually a minimum GCSE grade in a related subject: a grade 6 in GCSE Maths for A-Level Maths, a grade 6 in the same subject for A-Level Sciences, and a grade 6 in English Literature for A-Level English Literature. New subjects (Psychology, Sociology, Economics, Politics) are usually gated by English and Maths grades.
Check the current published requirements on each sixth form's website. They can shift year to year, and any figures in a blog post or a friend's older sibling's memory may be out of date.
Entry requirements are minimums, not targets. Meeting the minimum means you can be considered; it does not guarantee a place. Very selective sixth forms may have more applicants than spaces and use grades to prioritise.

Step 4: Complete each application
Once you have your shortlist, work through the application forms. Most sixth forms use their own online form, though some still accept paper applications.
Expect to be asked for the basics: Your name, contact details, current school, predicted GCSE grades, and the A-Level subjects you want to study in sixth form. Many forms also ask for a short personal statement (typically 500 to 800 words) and a reference from your current school. We have a full guide on writing a sixth form personal statement with examples of strong and weak lines. Some more selective sixth forms invite shortlisted applicants to an interview or subject-specific discussion.
Submit well before the deadline. Applications are typically not first-come-first-served, but leaving it to the last day gives you no room if the site crashes, your reference is delayed, or you spot a mistake.
Keep copies of everything you submit, including your personal statement. If you are applying to several places, having the previous version to hand makes the next one much faster to write.
Step 5: Interviews and taster sessions
Not every sixth form interviews. Some accept students purely on the application form and predicted grades; others hold subject-specific discussions where a teacher from each of your target subjects meets you for 10 to 20 minutes to check the fit.
Interviews at sixth form level are not designed to catch you out. They are a chance for the sixth form to check three things: You understand what the subject involves at A-Level (which is not always the same as at GCSE), you have genuine interest in it, and you will engage with the sixth form community. Prepare by revisiting your personal statement and reading around each subject.
Step 6: Manage your offers
Offers are almost always conditional on your GCSE results, and typically require a general grade profile plus a minimum grade in each of your chosen A-Level subjects. If you have offers from more than one sixth form, you can usually hold them all until GCSE results day, then confirm one and decline the others. Let the sixth forms you are turning down know promptly so they can offer the space to someone on their waiting list.
How many sixth forms to apply to
There is no rule, but three to five is a sensible spread for most students. Fewer than three leaves you exposed if results are lower than expected or an offer is withdrawn. More than five gets hard to manage, especially when each application is a separate form.
A good spread looks something like this. One aspirational choice, where the entry requirements are at the upper end of what you might achieve. Two or three realistic choices, where the requirements match your predicted grades comfortably. One safety choice, where the requirements are clearly below your predictions and you would be confident of a place even if results go badly.
Work through these in order, and give yourself deadlines earlier than the official ones so you have buffer time.
- Draft a longlist of sixth forms within reasonable travel distance
- Check that each one offers the subjects and qualifications you want
- Check entry requirements against your predicted grades
- Attend open evenings and (where offered) taster days
- Narrow the longlist to three to five sixth forms
- Draft a personal statement and adapt it for each application
- Ask your current school for a reference well before the deadline
- Complete and submit each application at least a week before the deadline
- Prepare for interviews or subject discussions where required
- Read every offer carefully before accepting
- Confirm your choice after GCSE results, and decline the rest promptly
What if it does not go to plan?
If you narrowly miss the required grades, contact the sixth form on results day. Most will consider borderline cases and may still offer a place, or suggest slightly different subjects that fit the grades you achieved.
If your first choice is definitively off the table, many sixth forms and colleges run late enrolment sessions in late August and early September for students in this position. Your current school will also have staff on hand on results day to help. And if you decide sixth form is not for you at all, alternatives include FE colleges, apprenticeships (search the government's Find an Apprenticeship service), and traineeships. Once you have a place, our guide on what to expect in Year 12 covers the step up from GCSE.
