We’re well into Basic Compliance Assessment (BCA) season. Student sponsors are required to request a BCA every 12 months, with a one-month window in which to make that request.
For many sponsors, that annual date falls between July and October, meaning compliance teams across the sector are currently checking, rechecking and trying to predict the numbers UKVI will shortly be assessing.
For clarity, sponsors don’t submit their own numbers – they simply confirm the date that the UKVI should take the calculations from, and hope that everything aligns with their own tracking.
For those working in student sponsor compliance, the BCA needs little introduction.
For university leaders who encounter it periodically through committees, dashboards or slightly nervous conversations with their compliance teams, what sits behind those three letters may be less obvious.
In many ways, the BCA is often viewed as a faceless metric and is only raised as a concern when the BCA letter arrives yearly and those metrics are, like an object in a rear view mirror, closer than they appeared in projections.
An annual assessment of visa refusals, enrolment and course completion, the calculations aren’t especially complicated, however knowing what your own numbers are, can be.
Three numbers, three calculations
The refusal rate looks at visa applications decided during the relevant 12-month period and the proportion refused. Enrolment considers students granted permission and whether they subsequently enrolled. Course completion looks at students whose expected course end date falls within the period and whether they completed.
The margins have also become much tighter. Since June, the refusal threshold has halved from 10% to 5% and the minimum enrolment rate has increased from 90% to 95%. From June 2027, minimum course completion increases from 85% to 90%.
Sponsors are monitoring all three – but the problem is that monitoring them isn’t necessarily the same as being able to reproduce UKVI’s calculation.
The refusal problem
We know when we’ve assigned a CAS and can see its status as it moves through the immigration system. What we don’t necessarily have is immediate visibility of the outcome of every application.
That uncertainty becomes particularly problematic because BCA season coincides rather neatly with the busiest period for CAS issuance and student visa applications.
A sponsor approaching its BCA submission can therefore have a significant number of applications progressing through the system without knowing what those decisions will be. A refusal rate becomes a broad range of possibilities at this time rather than a precise figure that can be controlled.
At a 10% refusal threshold, perhaps the uncertainty felt manageable. At 5%, considerably less so. There is no margin for error.
This leads to a conundrum around BCA submission – do you delay your submission under the hope that more visas are granted to assist in your BCA statistics, or do you submit immediately before further refusals might come?
How do you gather this information, when there is an inherit lag between a decision being made on a visa application to when you are being informed of the outcome?
Sitting close to the line
The latest Home Office quarterly migration data demonstrates why the stakes are so high. Across the four quarters to June 2026, the student route visa refusal rate was around 4.9%.
That isn’t a BCA rate and shouldn’t be treated as one. Individual sponsors recruit different students, from different markets and at different volumes. But a sector-wide figure sitting that close to the 5% threshold is uncomfortable. Inevitably, plenty of sponsors will be above 4%, and some above 5%.
There was hope that the refusal issues evident around the January intake would improve as sponsors tightened recruitment practices, introduced additional checks and reconsidered recruitment from higher-risk markets but early evidence indicates September isn’t reassuring. If anything, some sponsors appear to be seeing refusal rates going up rather than down.
It is, effectively, playing darts blindfolded in some cases, or whack-a-mole compliance: institutions are responding to problems only once they emerge, rather than having the data to anticipate where the next pressure point might be
We’ll need the published data before knowing whether that is a wider trend. But there is another complication for individual sponsors: a BCA looks backwards over 12 months. Depending on when a sponsor’s annual assessment falls, a particularly difficult peak visa period can potentially affect two successive BCA cycles.
One bad September may not just be this year’s problem. A market that has presented little concern in one recruitment cycle can produce a markedly different refusal profile in the next.

And then there’s completion rates
Anecdotally, enrolment isn’t currently generating the same level of concern but course completion is different.
For now, the minimum remains 85%. From June 2027, it becomes 90%.
When a sponsored student stops studying, we report that to UKVI. But not everyone who leaves their original course ultimately counts against the sponsor’s completion rate. Some will have left the UK, switched immigration category or moved to another sponsor.
UKVI may know that. The original sponsor frequently doesn’t.
Unsurprisingly, students whose sponsorship has been withdrawn aren’t always particularly enthusiastic about keeping their former university updated on what they do next.
Sponsors can therefore calculate a crude completion rate from their own records, but cannot always reproduce the calculation UKVI will eventually make.
Historically, that uncertainty was relatively manageable. If your own data suggested a completion rate of around 85%, experience might tell you that after UKVI applied the relevant discounts, the eventual figure would probably land somewhere around 90%.
The problem is that exactly the same position will suddenly become rather awkward next year when 90% becomes the minimum.
Imagine explaining to your senior leadership team: “We’ve reported 13% as not completing, but we’re confident at least 3% will have left the UK or changed immigration category.”
This means that any projections you give on this metric are often incorrect and then leads to a further level of scrutiny from your senior leadership team as to if your statistics and projections are correct.
Perhaps you’re above 90%. Perhaps you’re sitting right on it. But what if we get these assumptions wrong? If you project yourself in the red on course completion and making significant in-year overhauls and changes to note that your completion rate on your BCA letter places you firmly in the green, do you risk being the boy who cried wolf?
A BCA is still just a BCA
There’s one final distinction worth making, particularly for university leaders. A BCA is important, but it isn’t synonymous with sponsor compliance.
It measures three outcomes. It doesn’t tell you whether attendance monitoring is effective, reporting is timely, records are being maintained properly, or whether your systems and controls would withstand a UKVI compliance visit.
A sponsor can have excellent BCA numbers and compliance problems elsewhere. Equally, a compliance lead expressing concern about a BCA isn’t necessarily saying that the institution is failing in its wider sponsor duties. It is a snapshot, albeit an increasingly important one.
Know your numbers – and their limitations
With tighter thresholds, institutions need to understand these numbers, and they need appropriate senior-level visibility. But our point here is that leaders also need to understand their limitations.
The answer to the vice chancellor’s request of “what is our refusal rate?” is often a range because so many decisions are still outstanding at peak times. This is the reality.
For completion rates, there is even more guess work with how many students the UKVI will discount having left the country. That isn’t visible to us until the BCA submission is already done.
Neither answer necessarily indicates poor monitoring.
It should be noted, we are aware of UKVI contacting sponsors when their stats are indicating a concern and this approach is something we should fully support – and we hope to see more of this for active interventions.
We have clear guidance on how UKVI will calculate your BCA. However, operating real-time admissions and compliance regimes without accurate, in-time data continues to remain one of the largest challenges we face.
