Sixth Form represents an important transitional phase in the UK education system, where students typically aged 16 to 18 pursue advanced level qualifications like A-levels or BTECs. But what is Sixth Form really about? In this blog article, we’ll explore what is Sixth Form in UK schools, how it differs from GCSE years, what you can expect academically and socially, and what makes Lord Wandsworth College one of the best Sixth Form options in Hampshire and beyond.
Understanding Sixth Form in the UK
To fully answer “what is Sixth Form in UK schools?”, let’s first look at how it began, before evolving into what it is today.
The Evolution of Sixth Form Education in England
The concept of Sixth Form in England dates back to the early 20th century, as schools introduced structured post-GCSE education to prepare students for university or the workplace. Over time, the Sixth Form evolved from a purely academic environment into a more holistic stage of personal development; incorporating leadership, career planning, and enrichment activities. Today, Sixth Forms are often part of secondary schools, independent schools, or dedicated Sixth Form colleges.

Key Differences Between GCSEs and Sixth Form
In GCSEs, students typically study a wide range of subjects, whereas Sixth Form allows them to focus on three or four A-level subjects or equivalent qualifications. Sixth Form demands greater independence, critical thinking, and self-management. Unlike the structured school day of earlier years, students often have study periods and are expected to take more responsibility for their learning.
What Age is Sixth Form in the UK?
Let’s take a look at the ages of Sixth Form students, along with the minimum grade requirements and what years Sixth Form covers.
Entry Requirements and Typical Student Age
Sixth Form usually starts at the age of 16, after students complete their GCSEs. Most pupils continue until they are 18. As such, the answer to “what age is Sixth Form in the UK?” is generally 16 to 18. Meanwhile, entry requirements often include a minimum number of GCSE passes—commonly five grades from 9 to 4 (equivalent to A* to C in the old grade system), which should include English and Maths.
What Years Does Sixth Form Cover?
Sixth Form covers the two final academic years in secondary education: Year 12 (Lower Sixth) and Year 13 (Upper Sixth). During this time, students prepare for A-levels or equivalent qualifications that serve as the main criteria for university admissions or employment.
What Do You Study in Sixth Form?
There’s a wide range of subjects that Sixth Form students are able to choose from.
A-Level Subjects and Other Qualifications
In Sixth Form, students usually study A-levels, which are rigorous academic qualifications recognised by universities worldwide. Options range from Mathematics and Sciences to Humanities and the Arts. Some Sixth Forms including LWC also offer BTECs or the Extended Project Qualification (EPQ), which allows students to research and present a topic of personal interest at a near-undergraduate level.
At Lord Wandsworth College, the curriculum for Sixth Form is broad and engaging. We offer a wide range of A-level subjects—from Business, the Sciences, and Technology, to the Arts, and Languages—with small class sizes (18 pupils or fewer per class) that allow for personalised attention. Along with other extensive enrichment programmes, LWC students are able to develop the attitudes, skills, and habits fundamental to academic and personal excellence.
To enter Sixth Form, students need to have strong GCSE results. It’s worth noting that GCSEs in England transitioned from the traditional A*–G grading system, to a numerical scale of 9–1. This change was implemented to better distinguish high-achieving students and align with more demanding academic expectations. Here’s a comparison of the old and new grading systems:
New GCSE Grades | Old GCSE Grades | Description |
---|---|---|
A* | 9 | Highest grade, above an A* |
A | 7–8 | Strong pass |
B | 6 | Good pass |
C | 4–5 | Standard pass (grade 4 = old C) |
D–G | 1–3 | Below standard pass |
U | U | Ungraded |

What is the Best Sixth Form in the UK or London?
Factors to Consider When Choosing the Best Sixth Form
If questions like “what is the best Sixth Form in the UK?” or “what is the best Sixth Form in London?” have ever crossed your mind, here are a few important factors to think about: academic results, subject options, location, co-curricular activities, university destinations, and pastoral support. The environment should also nurture both academic potential and personal growth.
Why Lord Wandsworth College Stands Out in Hampshire
Lord Wandsworth College excels across the board—from exam results to student wellbeing. For starters, our Sixth Form students have an impressive track record, with 51% of results being grades A*-A, nearly 77% A*-B, and a pass rate of 100%. What’s more, we’re continuously investing in our pupils and modern facilities (like our new Sixth Form Centre and state-of-the-art Flowers Science Centre) designed to foster collaboration and independent study. What’s more, LWC is located just an hour from Central London, thus combining accessibility with a 1,200-acre countryside campus. And that’s not all—pupils also benefit from our outstanding pastoral support and dedicated academic staff who guide them through UCAS applications, career planning, and work experience opportunities.

Personal Development, Leadership & Co-Curricular
Sixth Form life at LWC is about more than academics. Pupils are encouraged to take on leadership roles and participate in a vast co-curricular programme, including the Duke of Edinburgh Award Programme, Science clubs, Performing Arts, and Sports. In fact, we encourage all our students to “dare greatly” in order to nurture bravery, independence, and compassion.
