Predicted Grades and References

How Teachers Calculate UCAS Predicted Grades

Teachers base your predicted grades on your academic performance across Year 12. They do not guess these numbers. They look at your formal mock exam results, marked coursework, end-of-topic tests, and overall consistency. These grades tell universities what you are most likely to achieve at the end of Year 13.

Your school or college submits these grades directly through the UCAS portal. You cannot type them in yourself. Admissions tutors use these predictions to screen applicants. If you apply for a Law degree requiring AAA, but your teachers predict BBB, the university admissions system will likely reject your application automatically.

Schools face immense pressure to get these predictions right. Many sixth forms use internal tracking software to ensure predictions remain realistic based on historical data. Teachers must justify their predictions to the head of sixth form. If you study BTECs, your teachers predict your final grade using the same rigorous internal tracking, aiming for Pass, Merit, Distinction, or Distinction*.

The timeline for predicted grades usually starts in the summer term of Year 12. Teachers draft initial grades after your summer mock exams. They review and finalise these grades in September of Year 13. You must know your final predicted grades before you start choosing your five UCAS university options.

The Gap Between Predicted and Achieved Results

Teachers want you to secure offers from good universities. They often give you the benefit of the doubt if you sit on the boundary between two grades. This optimism creates a massive discrepancy between what students expect to get and what they actually open on results day.

According to the Economics Observatory (2020), 75% of students receive over-predicted grades. Only 8% of students end up with under-predicted grades. Over-prediction sounds helpful, but it causes severe problems during the admissions cycle. If you hold offers that demand higher grades than you can realistically achieve, you risk losing all your university places in August.

UCAS recently launched a pilot scheme providing personalised reports to over 1,000 schools to help improve prediction accuracy. According to UCAS (2025), the gap between predicted and actual grades has been growing, with accuracy falling to around 30% in recent years. Universities know that predictions are often inflated. This is why many institutions now rely heavily on contextual data and your personal statement to make their final decisions.

You must balance your five UCAS choices to protect yourself against over-prediction. Include at least one safe choice with entry requirements one or two grades below your predictions. Read our university applications guide to understand how to build a sensible shortlist of courses.

What to Do If Your Predicted Grades Are Too Low

You have the right to challenge your predicted grades if you believe they do not reflect your true academic ability. You must initiate this process early in the autumn term of Year 13. Once your school attaches your reference and sends your application to UCAS, the grades are permanently locked.

Start by checking your school’s official appeals policy. Most sixth forms require you to submit a formal request to the head of year. Do not ambush your teacher in the corridor. Book a formal meeting and bring hard evidence to support your case. A simple promise to revise harder carries no weight.

Bring your marked coursework, recent test papers, and any independent essays you have completed. If you scored 75% on a formal mock exam but received a predicted grade of a C, you have strong grounds for an appeal. Present this evidence calmly and professionally.

If your school refuses to change the grade, you must adapt your university choices immediately. Applying to courses with entry requirements higher than your predicted grades almost always results in a wasted UCAS choice. You will also struggle to secure accommodation if you rely on an unrealistic insurance choice, so read our student housing section to understand your backup options.

The Three-Part UCAS Reference Format

UCAS completely overhauled the teacher reference system for recent application cycles. Referees no longer write a continuous, free-text letter of recommendation. They now complete three highly structured sections designed to give universities clear, comparable data.

Section one provides a general statement about your school or college. Universities need this context to judge your achievements fairly. If you achieve ABB at a school where the historical average is CCE, you are performing exceptionally well. Your referee will detail the school demographic, progression rates to higher education, and any major disruptions like building work or severe staffing shortages.

Section two covers extenuating circumstances. This is an optional box where your referee explains personal issues that directly affected your academic performance.

Section three contains supportive information specific to you. Your referee will highlight your academic strengths, your suitability for your chosen course, and any relevant extracurricular achievements. If you are applying for Engineering, your referee will include specific comments from your Physics and Maths teachers regarding your analytical skills.

Aligning Your Reference with the 2026 Personal Statement

For students applying for 2026 entry, UCAS has replaced the traditional free-text personal statement with three structured questions. You must now answer specific prompts about your motivation for the course, your academic readiness, and your relevant extracurricular experiences.

Because your personal statement is now strictly formatted, your teacher reference becomes even more important. Your referee must use section three to fill in any gaps that the new personal statement questions do not cover.

If you use your personal statement to discuss a specific physics project, your referee can use their section to praise your leadership skills during a completely different chemistry experiment. This collaborative approach ensures the university sees a broad, detailed view of your abilities.

Who to Ask for Your UCAS Reference

If you apply through a school or college, you do not need to choose a referee. Your centre handles the reference automatically. You will enter a buzzword when you register on UCAS, which links your application to your school. Usually, your form tutor or head of sixth form writes the final version of the reference, gathering comments from your individual subject teachers.

Independent applicants face a completely different process. If you are a mature student or applying after a gap year without school support, you must find a suitable referee yourself. You enter their email address on the UCAS portal, and UCAS sends them a secure link to complete the three sections.

You must choose someone who knows you academically or professionally. Good options include a former teacher, a current line manager, or a supervisor from an Access to Higher Education course. Contact your chosen referee at least two months before the January UCAS equal consideration deadline. They need plenty of time to register on the portal and draft their response.

Send your referee a summary of your recent achievements, your target courses, and a draft of your personal statement. This helps them write a highly specific and supportive section three. Ensure they understand the new three-part format, especially if they have not written a UCAS reference in recent years.

Handling Extenuating Circumstances in Your Reference

Universities need to know if severe illness, bereavement, caring responsibilities, or family issues disrupted your education. The best place for this information is section two of your teacher reference.

Having your referee explain these circumstances carries significantly more weight than writing about them yourself. It provides official verification from an educational professional. It also saves your personal statement character count, allowing you to focus entirely on discussing your academic interests and course suitability.

You must speak to your referee well before they write the reference. Give them clear, written permission to share your situation with universities. Be specific about the dates of the disruption and exactly how it impacted your grades or attendance.

Some highly selective universities require you to submit a separate extenuating circumstances form directly to their admissions team, alongside the UCAS reference. Always check the specific admissions policy on the university website.
