Every August somebody in a Scottish school corridor says the boundaries were “moved to fail people”, and somebody else says they were “dropped because everyone flopped”. Both are wrong, and the real process is more interesting than either.

This is what happens to your marks after you hand in the paper.

The number the exam was designed around

Every National 5, Higher and Advanced Higher course assessment is built with a set of target boundaries in mind. Qualifications Scotland calls these notional grade boundaries, and they are:

Grade	Notional boundary
A	70% of the maximum marks
B	60%
C	50%
D	40%

Those figures are the starting point for the discussion, not the answer. Here is what the answer actually looked like in 2026. The question paper writers aim at that level of difficulty. Whether they hit it is another matter, and nobody knows until 100,000 or so candidates have sat the thing.

There is also an upper A boundary, set at a notional 85 per cent, which splits the A grade into two bands.

What an A really cost in 2026

We downloaded the official boundaries file and worked out every boundary as a share of the marks available. Across 47 Higher subjects the median A did land on 70 per cent, so the notional figure is honest as an average. It is the spread that people never see.

In 14 of those 47 subjects, an A took less than 70 per cent. In 19 of them, a C took less than half the marks.

Higher 2026	Marks available	A boundary	A as % of marks	C as % of marks
Media	100	66	66.0%	48.0%
Psychology	120	80	66.7%	45.8%
Physical Education	100	68	68.0%	48.0%
Physics	150	102	68.0%	47.3%
Politics	110	75	68.2%	46.4%
Administration and IT	120	82	68.3%	48.3%
English	100	71	71.0%	52.0%
Engineering Science	160	117	73.1%	56.2%

So the same letter cost 66 per cent in Higher Media and 73.1 per cent in Higher Engineering Science. Seven marks in a hundred separate those two, and no pupil chose which paper turned out harder to write.

Advanced Higher runs lower still. The most striking figure in the whole 2026 file is Advanced Higher Biology, where an A took 98 marks out of 160, which is 61.3 per cent, and a C took 69, which is 43.1 per cent. Across 35 Advanced Higher subjects the A boundary ranged from 61.3 per cent to 72.0 per cent, and 13 of them sat below 70.

If you are looking at a mark in the fifties and assuming you failed, check the actual boundary for your subject before you conclude anything. In nineteen Higher subjects this year, half the marks was a pass with room to spare.

One trap when comparing years, and it catches journalists every August. The number of marks available changes too. A headline saying the pass mark fell means nothing unless the paper was the same length. The official file carries five years in one workbook, so you can check both columns yourself rather than trusting a percentage someone calculated for you.

Figures above are from the Qualifications Scotland grade boundaries workbook for 2026, which is published on results day and contains 2022 through 2026.

Why the boundary moves

Here is the logic, and once you see it the whole thing stops feeling arbitrary.

An A in Higher Chemistry this year has to mean roughly what an A in Higher Chemistry meant last year. It also has to mean roughly what an A in Higher French means. If this year’s paper turned out harder than intended, and the boundary stayed at 70 per cent, then this year’s cohort would be punished for a drafting decision they had no part in. So the boundary comes down. If the paper was easier than intended, it goes up.

Qualifications Scotland puts it plainly: if a course assessment has been easier or more difficult than intended, the boundaries are adjusted so that the level of difficulty required to achieve an A, B, C or D stays the same from one year to the next.

The adjustment is meant to be evidenced, not felt. Where a specific question did not perform as expected, analysis of that question shows how many marks harder or easier the paper was, and which candidates were affected, so the panel can see which boundaries need to move.

Who decides, and how

Around 7,700 teachers and lecturers mark the exams and coursework in a Scottish diet. Once marking is done, awarding meetings take place, more than 140 of them, packed into a few weeks between June and July.

Each meeting has a fixed cast:

• a chair, the chief examining officer or a senior member of staff, who makes sure procedure is followed and the approach is consistent across subjects
• an advisor to the chair, a head of service, whose job is to interrogate the arguments being put forward
• the principal assessor, the subject expert who proposes and has to justify the boundaries
• the principal verifier, where coursework is internally assessed, reporting on how that performed
• a qualifications manager
• a statistician, who provides the data and records the decision

Before the meeting the principal assessor writes a Statement of Intent saying whether they expect the boundaries to be notional, the same as last year’s, or somewhere in between. The meeting then works through three questions: did the assessment function as intended, how does performance compare with previous years, and has performance changed since last year.

One detail worth knowing. The panel sets the minimum mark for a C, for an A, and for an upper A. The B and D boundaries are then calculated automatically from those decisions. So nobody sits in a room arguing about where the B goes.

Scotland does not grade on a curve

This is the myth worth killing. There is no quota. Qualifications Scotland’s own guidance says there is no fixed proportion of grades, and that the ability of the candidates has to be reflected in the grade distribution, because doing otherwise would be unfair.

The technical term for the Scottish approach is attainment-referenced. Expert judgement of how the assessment performed, measured against defined criteria, with statistics used to check whether the outcome is plausible. Compare that with a norm-referenced system, which holds the same outcomes steady regardless of how well the cohort actually did. Scotland does not do that.

Which means: a strong year genuinely can produce more A grades. Your classmates are not your competition for a fixed pool of passes.

D, No Award, and the thing there is no safety net for

Grade D represents 40 to 49 per cent in the course assessment, and it is an award. It goes on your certificate. Below 40 per cent is No Award, which means the course has not been passed and no grade appears.

There is no automatic fallback in Scotland. Failing a National 5 does not hand you a National 4. If a grade is missing from your certificate for a National Course, that normally means No Award, and it should be mentioned in the letter that came with the certificate.

Bands: the number that is not on your certificate

Behind every A to D sits a band, and the band tells you where in the grade you landed.

Band	Result
1	Upper A
2	Lower A
3	Upper B
4	Lower B
5	Upper C
6	Lower C
7	Grade D

None of that is printed on your Scottish Qualifications Certificate. Your school, college or training provider can tell you your band and your marks for each component, though the data goes to the co-ordinator at your centre and you may need to wait until term starts. You can also ask Qualifications Scotland directly through a subject access request, using your name, Scottish Candidate Number and date of birth.

If you are even thinking about an appeal, get this number first. A band 4 B two marks off an A is a completely different situation from a band 3 B, and the same word appears on your certificate either way. Our guide to SQA appeals explains why that matters, including the risk of a grade dropping.

What about scaling?

Scaling is a separate thing from boundary setting, and it is where the published information gets thin.

Qualifications Scotland’s statistics notes state that published mark data refers to marks after scaling, where scaling is applied. So scaling does happen, on some components of some courses, and a scaling table is published for National 5 and Higher ESOL. What is not published in one plain place is a full list of which courses scale which components, or by how much.

We are not going to invent a figure to fill that gap. If it matters to you, ask your subject teacher whether your course has a scaled component, or contact Qualifications Scotland on 0345 279 1000. Do not trust a forum post that claims to know the multiplier.

Questions

When are the grade boundaries published?

On results day. The Grade Boundaries 2026 publication came out on 4 August 2026, covering National 5, Higher and Advanced Higher.

Can I work out my grade before results day?

No, and anyone selling you a prediction is guessing. The boundaries do not exist until the awarding meeting has happened, and they are not released until the certificates go out.

Are the boundaries the same for coursework and the exam separately?

No. Boundaries are set on the total mark across all components of the course assessment. A strong assignment can carry a weaker exam and the other way round.

Why did the boundary in my subject move so much this year?

Because the panel judged that the paper did not sit at its intended level of demand. The published boundaries show the change, but the reasoning behind an individual subject’s decision is not published candidate by candidate.

Does a lower boundary mean the qualification is worth less?

The stated aim of moving the boundary is the opposite: to keep the standard steady so that the grade holds its value year on year. A B in a year with a 55 per cent boundary is meant to represent the same attainment as a B in a year with a 62 per cent boundary.
