Starting Sixth Form: 5 Steps for US University Applications

How does the US application timeline fit alongside UCAS in Lower Sixth?

For pupils in the England and Wales year-group system starting Lower Sixth (Year 12) in September 2026, the US university admissions process begins earlier than many families expect. US applications are submitted in the autumn of Upper Sixth (Year 13). For this cohort, that means autumn 2027, with early-round deadlines often around 1 November, for university entry in autumn 2028. Most Guidewell Global families run UCAS and US applications in parallel, which makes Year 12 the natural preparation year for the US side of your plans.

I hope the thought of navigating this transition brings excitement more than nerves. Taking a few targeted steps early in the Sixth Form helps you build your academic and extracurricular foundation.

1. Get into good study habits from the very first term

You may have more independence in the Sixth Form and, depending on your curriculum, a lighter timetable. Get into the habit of using any free periods productively from the very first term: consolidate your notes, practise applying new concepts, and read around your subjects.

These habits also prepare you for the mock A level or IB examinations you sit during the Sixth Form. Mocks are often important assessments that help your school work out your predicted marks, and they can inform the predicted grades used for UCAS. For US applications, the school's predicted marks appear in the transcript it prepares: a record UK schools produce specifically for US universities, since they do not issue transcripts as standard. One set of mocks, two application systems. For further detail on course loads, explore our guide to strategic academic planning and course selection.

2. Plan your SAT or ACT testing timeline

Admissions testing needs early attention. Testing preparation ideally begins in the summer following Year 11.

The standard Guidewell testing timeline involves sitting your first SAT or ACT in the autumn of Year 12, allowing room for a retake if necessary, with the aim of completing all testing by the summer after Year 12. That means a student reading this at the start of Sixth Form should already have preparation underway. If yours is not, set your testing plan now. You can explore tailored support through our SAT and ACT preparation programmes.

3. Seek out leadership and build extracurricular depth

US universities are interested in the activities you have been involved in across the four years before university. That four-year window spans Years 10 to 13, so activities from your GCSE years count towards your profile.

Focus your energy on demonstrating depth in a small number of areas rather than accumulating superficial memberships. You do not have to become the head of your school or a prefect to be a leader. Leading a club or society is a great place to start, and try to attend any exploratory fairs your school holds for the Sixth Form. If an activity you have always wanted to be involved in does not yet exist at your school, now is the time to take the lead and develop that initiative yourself. Some leadership roles are not passed down to Lower Sixth students until the Upper Sixth begin their exam revision period, but you can start conversations with students and staff now about the criteria that will be considered when those handover decisions are made.

4. Review your subject choices and dig into specialisation

Most schools will allow some flexibility in subject and even curriculum choice in the first part of the autumn term, so think carefully about whether your subjects suit your academic strengths and future plans; a lot can change between finishing GCSEs and starting the Sixth Form. If you think you would benefit from reconsidering your selection, have a conversation with your Head of Sixth Form, and consult our advice on how to choose your Sixth Form subjects.

For some students, this might look like taking on a fourth (or even a fifth!) A level subject to increase the challenge of your course load, or adjusting your subject selection now that you know how you performed at GCSE. In my experience, it is better to start out with more challenge in the Sixth Form and reduce this as necessary rather than trying to do the opposite later on.

The last two years of school are also a great time to start building competence and expertise in a few academic areas that really interest you:

• A level pupils: the A level curriculum encourages this by providing the opportunity for narrowed, more intensive study of your chosen subjects.
• IB pupils: the Extended Essay and CAS project can be excellent opportunities to dive deeper into the areas of your subjects that interest you most.

5. Make sure your school knows you plan to apply to the US

Learn who your school's contact for US university applications is and introduce yourself early. This is especially important if you are starting the Sixth Form at a new school, so that you are on their radar.

Building a good relationship with your school counsellor matters: they will be an important school resource for you over the next two years, and they may even write a letter of recommendation on your behalf. Reviewing key questions to ask your school counsellor will help guide your first conversations. This is also a good time to begin working with an independent university admissions counsellor, if you have not done so yet.

What should families do now?

• Map your timeline: Lay out internal school mock dates, UCAS deadlines, and US early application target dates across Years 12 and 13.
• Audit your activity log: Record extracurricular activities and leadership roles from Year 10 onwards.
• Review subject choices: Speak with your Head of Sixth Form during the early weeks of term if your current A level or IB subjects need adjustment.
• Set your testing plan: Determine whether you will take the SAT or ACT and set a study timeline; preparation should already be underway as Sixth Form begins.
• Connect with your counsellor: Introduce yourself to the member of staff who handles US applications and begin building that relationship.

The transition from GCSE to Sixth Form can be a time of serious growth, and I always enjoy looking back on the incredible personal and academic development that some of my students have made during this period. If you make specific plans to act on these five steps, your Sixth Form experience and your US applications will be far smoother.

So best of luck, enjoy the new opportunities, and if you would like to talk through your family's admissions plan, book a consultation with our counselling team.
