Short answer first: it depends on your university and usually on your programme. Leeds expects physical attendance at lectures, seminars, laboratory sessions, tutorials, workshops, fieldtrips and placements. Manchester's business school makes attendance at all classes compulsory and spot-checks lectures. St Andrews computer science says the opposite about lectures, that attendance is not compulsory but strongly recommended, while tutorials carry a register. King's asks for 100 per cent and makes laboratory attendance mandatory for progression. If you hold a Student visa, none of it is discretionary.
Below are the policies themselves, what actually triggers a warning, and what the research says about how much attendance is enough. Your own programme handbook is the document that decides your case.
Who sets the rules, the university or the school?
Both, and the school usually wins. UK universities publish a framework and then hand the detail to faculties and schools, which is why two students at the same institution get different answers. Leeds's policy is explicit that faculties and schools must clearly communicate their attendance and engagement expectations to students. If you arrived from sixth form expecting a single register-based rule, the shift is the same one described in going from A-levels to first-year study.
- Leeds sets the widest expectation. The policy covers physical attendance at scheduled teaching and other learning events as required by the programme, and lists lectures, seminars, laboratory sessions, tutorials, workshops, fieldtrips, practice placements and examinations.
- Manchester's business school makes it flat. The undergraduate handbook states that students attendance at all classes is compulsory and will be monitored across seminars, tutorials, labs and workshops, and adds that spot checks across lectures may also be undertaken each year.
- St Andrews computer science separates the two. The handbook says attendance at lectures is not compulsory, but it is very strongly recommended, while for tutorials attendance is a compulsory element of the module, with a register held on the student records system.
- King's asks for everything. Its natural, mathematical and engineering sciences guidance tells students to aim for 100 per cent attendance at all scheduled teaching activities, including lectures, workshops and tutorials, and states that laboratory attendance is mandatory for progression on chemistry courses.
So the honest general answer is that lectures are the flexible part of a UK timetable and everything else is not. That is a description of what the policies say, not permission.
Which sessions are actually compulsory?
The pattern holds across the policies above, and it follows the logic of what cannot be repeated. A lecture can be delivered again through a recording. A titration, a seminar discussion you were meant to lead, a clinical placement shift and an in-class test cannot.
| Session | Usually compulsory | What the policies say |
|---|---|---|
| Lectures | Sometimes | Compulsory at Leeds and King's, spot-checked at Manchester's business school, not compulsory at St Andrews computer science |
| Seminars and tutorials | Yes | Registers taken; a compulsory element of the module at St Andrews |
| Labs and practicals | Yes | Mandatory for progression on King's chemistry courses |
| Workshops | Yes | Monitored alongside seminars and labs at Manchester |
| Placements and fieldtrips | Yes | Named in the Leeds policy, and usually governed by a professional body as well |
| In-class tests and presentations | Yes | King's gives a mark of zero without a mitigating circumstances form |
| Personal tutor meetings | Yes | Counted as engagement at Leeds and King's, and York counts supervision meetings |
| Drop-in and optional revision sessions | No | Attendance is normally recorded but not required |
What this means for the week is that missing a lecture costs you information you can recover, and missing a lab costs you a mark you often cannot. When you have a clash, protect the session you cannot repeat. The kind of note each of these sessions actually needs is a separate question, covered in taking notes in seminars, labs and tutorials.
There is usually a legitimate way to move the compulsory ones. Most schools run several seminar and lab groups for the same module, and a one-off swap into another group is a routine request if you ask the module administrator a few days ahead rather than the morning of. A swap keeps the attendance record clean, which an apology afterwards does not. Repeat requests get refused, so spend them on the weeks that matter: a shift you cannot drop, a medical appointment, a funeral.
How is your attendance actually tracked?
Paper registers have mostly gone. Many UK universities now run an attendance or engagement platform, and the data goes to a dashboard your school can read week by week.
Manchester's business school requires the Student Engagement and Attendance System, where you download an app, sign in with your university email and scan a QR code at each teaching event. York records engagement at lectures, seminars, labs and other small group teaching sessions, plus supervision meetings and all summative, open and closed assessments, and identifies students below its engagement thresholds at weeks 5 and 10. St Andrews computer science keeps tutorial registers on MMS. Leeds records both attendance and engagement, and its records distinguish between physical and virtual attendance.
The consequence is that nobody has to notice you are missing. The system notices, and it notices the pattern rather than the incident, which is why a student who attends three quarters of everything is invisible and a student who has stopped attending one module entirely is flagged.
The other half of the system is the absence you report yourself. Manchester's business school asks students to log absences through the same app with a reason, and states that non-attendance is only acceptable on health or compassionate grounds, with the expectation that you catch up on the work. A logged absence and an unexplained gap look identical to you and completely different on the dashboard your school reads. Two minutes on the morning you are ill is the cheapest administrative work in the degree.
What triggers a warning or a withdrawal?
Every procedure starts with a school trying to make contact, and every procedure ends in the same place if it fails. Leeds is clearest about the sequence. If a school has concerns about your attendance or engagement, they will contact you, and if matters do not improve you are invited to a meeting to discuss support to re-engage. After that comes a withdrawal warning, and Leeds will presume withdrawal has occurred where you have received that warning and have not responded or your attendance has not improved. The university policy puts the end point plainly: where attendance or engagement continues to be unsatisfactory, and no mitigation is evidenced, students may be withdrawn from the University.
Manchester's business school describes the same shape with different names. Unsatisfactory engagement brings contact from the student support and wellbeing team, then a meeting with your academic advisor, and the Director of Undergraduate Studies may issue a letter of refusal, which excludes you from formal assessment and terminates the degree programme. King's adds the sharpest single rule: if you do not attend an in-course assessment and do not submit a mitigating circumstances form, you receive a mark of zero.
The email you should not ignore
The email from your school asking whether everything is all right is not a formality, and it is not a telling-off. It is the first stage of a documented procedure, and answering it is what keeps you in the support half of that procedure rather than the withdrawal half. Reply the same day, say what has happened in two sentences, and ask for a meeting. A student who replies almost never reaches a withdrawal warning.
What changes if you are on a Student visa?
Your university is not just teaching you, it is sponsoring your permission to be in the country, and that duty is enforced. The Home Office's student sponsor compliance guidance lists failure to monitor student attendance or academic engagement effectively among the compliance failings that count as a serious breach of sponsorship duties, and its sponsorship duties guidance requires sponsors to keep a record of each student's absence and attendance.
That duty lands on you through the university. Leeds states that it has a legal responsibility to report any serious case of non-attendance by an international student with a student visa to the UK government, because it may break the visa rules, and that it has ten days following final notification to inform UK Visas and Immigration. York frames its own check-in system partly as protection for the university's UKVI licence to sponsor students, while stressing that visa holders follow exactly the same process for registering engagement as everyone else.
Two practical points follow. Contact points are not only teaching: supervision meetings, assessments and tutor meetings all count, so a research student with few timetabled hours can still miss engagement points without missing a class. And if illness or a family emergency is going to keep you away, tell the international student support team early, because an authorised absence recorded in advance is a different record from a silence. More on how the visa shapes the rest of the degree is in lectures as an international student in the UK.
Does watching the recording count as attending?
Not in the policies we read. York is direct: it is only looking at attendance at physical events as a way of knowing whether students are engaging with on-campus events. Leeds separates the two categories, recording attendance and engagement distinctly and listing accessing online learning materials, including viewing recap recordings, as engagement rather than attendance. Where a programme or a session is designated as online or hybrid, Leeds says virtual participation may be required or permitted, such as joining a live session by video conferencing, and in all other cases it expects students to attend in person.
So the recording protects your learning and not your record. It is still the right tool when you have genuinely missed a session, and what your university is obliged to publish, how long the file stays up and what you may do with it are set out in lecture capture at UK universities.
What does the evidence say about attendance and marks?
The research is more interesting than the slogan. A 2026 study in Frontiers in Education modelled attendance and course marks for 181 undergraduates across seven STEM courses. Across the whole sample, a 10 per cent increase in class attendance corresponded on average to a 5.58 per cent increase in course marks. The study also found a threshold rather than a straight line: below roughly 74 per cent attendance there was no statistically significant association between attending and marks, and above it the relationship became strongly positive. The study was run at a Canadian university, so treat the exact breakpoint as indicative rather than a rule for your own module.
The useful reading is that partial attendance behaves like non-attendance. A student at half attendance is not getting half the benefit, because the value comes from having the whole thread of a module rather than a set of disconnected hours.
Recording changes behaviour, too. Writing for the British Educational Research Association, Andrew Woon points to a Leeds study in which attendance fell from 85.7 per cent to 81 per cent once lecture capture became available, and attributes much of the wider decline to the paid work students now do alongside study.
What do you do when you have missed several weeks?
Start with the people, not the material. Email your personal tutor or school office before they email you, and say how many weeks you have missed and why. Every procedure above begins with a school attempting contact, so making the first move moves you into the support route.
The week you come back
- Ask which sessions cannot be made up. Labs, placements and in-class assessments usually cannot, and those need a mitigating circumstances form, not a catch-up plan.
- Ask whether any assessment deadline has passed or is close, and whether an extension is available.
- List the missed lectures by module, and rank them by what the next assessment covers.
- Work through them at about one lecture per 30 focused minutes, using the slides first and the recording only for the parts you cannot reconstruct.
- Go to everything for the next two weeks, including the sessions you would normally skip, because the pattern is what your school is watching.
Do not try to clear four weeks in a weekend. Two catch-up hours a day for a fortnight, alongside current teaching, ends with you back in the module. A single heroic Sunday ends with you behind on the following week as well.
Where Notibo fits
Catching up is where this gets expensive, because a missed lecture costs more time to recover than it did to attend. Notibo records a lecture, or takes an audio file you upload, and returns a transcript, structured notes and flashcards with spaced repetition, so a session you had to miss becomes something you can revise from rather than an hour of video to sit through. It does the same with PDF, PPTX and DOCX files, which is often all you have when you were not in the room.
You can try Pro free for 14 days, with 240 minutes of recording and no card. After that the free plan covers 30 minutes of recording a month. Pro is 9.99 euro a month or 88.99 euro a year, priced in euro with the local amount shown at checkout. Uploads are capped at 50 MB, and long recordings are saved in smaller parts as they run and joined back into one transcript. Files are stored in the EU, on Supabase in Frankfurt, and transcription and the AI notes run on US processors under standard contractual clauses. Transcription covers 89 languages and the transcript comes back in the language spoken. None of this makes you present: recording needs your lecturer's permission, and an attendance record is still an attendance record.
