What should a Cambridge academic reference letter include for an undergraduate application?

For Cambridge undergraduate applications, the reference should be much more academic and course-specific than a typical U.S. recommendation. The goal is to help Cambridge judge whether you are academically prepared for the specific subject you want to study and whether you are likely to thrive in a very rigorous, specialized course.

The strongest reference usually includes your current and predicted grades, your performance in the most relevant subjects, and clear evidence of academic ability in the field you are applying for. It should comment on things like analytical skill, depth of understanding, intellectual curiosity, quality of written work, class performance, discussion ability, and how you compare with other strong students the teacher has taught.

It also helps if the referee explains why your school record supports your chosen course. For example, if you are applying for Engineering, the letter should emphasize math and physics strength, problem-solving, and advanced coursework. If you are applying for History, it should focus on reading, argument, source analysis, and sustained essay work.

Cambridge references are usually less about personality, leadership, kindness, or extracurricular involvement unless those things directly support academic readiness. General praise like “hardworking” or “pleasant to teach” is much less useful than specific academic observations such as how you handle difficult material, contribute to high-level discussion, or perform on demanding assessments.

If there were any unusual circumstances that affected your education, the reference can also briefly explain them. It may also mention relevant supercurricular engagement, such as wider reading, competitions, research, or academic projects, but only when those activities genuinely connect to your subject.

The best person to write it is usually someone who knows your academic work well in a subject closely related to your intended course, or someone coordinating a school reference who can incorporate detailed subject-teacher input.
