Evidence
Admissions outcomes, institutional publications, and subject-level patterns, gathered course by course and dated to the cycle they describe.
Delta Research Group
We research how admissions decisions are actually made.
Selective UK admissions run as dozens of separate processes, each with its own tests, weightings, and stages, and each revised from one cycle to the next. We study them closely, then build what we find into tools for students, teachers, and guidance counsellors.

2027 entryWhy this work matters
A single application, a sequence of separate decisions.
Every selective course runs an admissions process of its own. The test changes, the weight carried by school results changes, and the stage at which the field narrows changes, often from one year to the next. Very little of that reaches a school in a form it can use.
Talent is widespread. Reliable information about admissions is not, and the distance between the two settles more applications than it should.
We areresearchers.
For every student
The test of research is whether it changes what a student does next.
Delta turns a developing application into concrete decisions: where to apply, what to prepare, and where the next hour of work will count for most.

For schools and advisers
A counsellor should be able to see a whole cohort at once.
Guidance staff carry more students than any one person can hold in mind, and the pupils who say least are often the ones who need the most. Delta assembles the same evidence for every pupil in the year group, so attention reaches the students it should.
- Find able pupils whose ambitions have been set too narrowly.
- Spot an exposed shortlist while there is still time to change it.
- Direct limited counselling hours towards the students who need them.

Our research
We go further into each process than a school reasonably can.
Our work draws on tens of thousands of historical admissions outcomes, published institutional evidence, subject-level trends, and expert judgement. Each course is held separately, and every figure is stamped with the cycle it describes, because a process that changed last year no longer describes this one.
We compare a student against the evidence that bears on their choices, carry the uncertainty through rather than round it away, and identify where further effort is most likely to alter the result.
Analysis
Statistical comparison against the pool that will decide the application, with uncertainty stated rather than smoothed over.
Application
A shortlist, a preparation priority, and a plan that a student and a counsellor can both read and act on.
What the research helps a school answer
Where does this student actually stand?
Measured against the pool that will decide the application, course by course.
What would most improve this application?
Preparation, choices, and time, placed in order of likely effect.
Who needs attention this week?
A ranked list for the counselling team, refreshed as the evidence moves.
The framework has been developed with Oxford and Cambridge professors, admissions tutors, and advisers at leading UK institutions.
Delta Briefings
We publish what we find.
Each briefing takes a single course or a single question, sets out the evidence behind it, and says plainly what that evidence does and does not support.
