DGSA Pass Mark and Pass Rates: Road Is Lowest in Most Sittings

Checked 28 October 2026. Pass rates from the SQA (now Qualifications Scotland): an FOI reply (March 2019 to November 2023) and its candidate performance reports (March 2024 to March 2025, read in archived copies of its retired exam site), the latest official figures we found. Pass mark read on GOV.UK on 28 October 2026.

Road had the lowest national pass rate of the three papers in four of the five sittings from March 2024 to March 2025, and was 51.5 % in March 2025. Across 2019 to 2023 it was 60 %, against 79 % for Core and 66 % for All Classes. The pass mark is 65 % in the syllabus and 32 marks out of 50 on the sample papers.

The pass mark: 65 % or 32 marks?

The GOV.UK syllabus says, for each paper, “The pass mark is 65%.” Each official sample paper says “You need to gain 32 marks to pass this paper.” Each paper is out of 50, so 32 marks is 64 % and 65 % is 32.5 marks. GOV.UK does not explain the difference, and it does not publish the marking scheme (the examiners’ reports refer to one).

In practice the half mark should not matter: if you are within a mark or two of either line on a practice paper, a few lost marks on the day could change the result. Treat 36 out of 50 as a working target (our suggestion).

Your practice mark against both pass lines

Enter your mark out of 50 on a full timed practice paper, in whole or half marks. The tool compares it with 32 marks (the line printed on the sample papers) and 65 % (the syllabus, which is 32.5 of 50).

A practice mark is only a guide: the real paper is marked by Qualifications Scotland, and GOV.UK does not publish the marking scheme.

Pass rates, 2024 to 2025

From March 2024 the SQA (now Qualifications Scotland) published a candidate performance report after each sitting, giving a national pass rate per paper and examiners’ comments. These were on its DGSA exam site, which has since closed (the exam pages moved to GOV.UK); we read archived copies.

What the figures say, and what they do not

ReadingDetail
Road was below Core at every sitting2019 to 2023: Core 67 % to 92 %, Road 48 % to 74 %. 2024 to 2025: Core 65.6 % to 85.3 %, Road 51.5 % to 63.9 %
Road is usually, not always, the lowestIn September 2024 All Classes (41.5 %) was below Road (55.3 %)
All Classes moves the mostFrom 41.5 % (September 2024) to 84 % (March 2023). The sources do not say why
They are rates per paper, not per personNeither source says how many people pass all three, or splits first attempts from resits
The latest official report we found is March 2025Check the exam’s GOV.UK pages for later figures

The first column is our reading of the FOI table and the reports.

Neither source gives a single reason for Road’s lower rate. The examiners’ comments on the November 2024 Road paper name the areas: “Many candidates lost marks by providing an incorrect or incomplete reference”; placing panels and placards on transport units carrying tanks “under both the UK CDG regulations and the ADR Agreement”; parking and supervision; and “confusion between mixed packing and mixed loading requirements”. Road is also the only one of the three papers with a case study, worth 35 of its 50 marks on the sample paper. The method we suggest is in our Road paper guide.

The fastest way to know which side of the line you are on is to sit a full paper and have it marked. The DGSA practice papers are 9 timed papers (3 Core, 3 All Classes, 3 Road) where you write your answers and each one is marked point by point, with the ADR, CDG2009, emergency action code list or derogation reference for every point you missed. One Core question is free to try.

Rail (91 %) and Inland Waterways (90 %) look easier over 2019 to 2023, but they are small: in February 2024 there were 14 Rail-only, 52 Road and Rail and 15 Inland Waterways certificate holders, against 2,068 Road. On small entries a rate can swing widely: Inland Waterways went from 100 % in September 2023 to 50 % in November 2023.

Where the marks go in a written, open-book paper

The DGSA papers are open book in the sense that you take printed regulations in. GOV.UK’s guidance says that, “When asked”, you need to provide references to the regulations you used and show the steps you took, and each paper says where a reference is wanted. The examiners’ reports repeat it: “Unless otherwise stated, references are required to support answers” (November 2024), and “showing such steps is regularly part of the marking scheme” (September 2024). That makes four ways to lose a mark you could have had:

Way to lose marksExampleFix (our suggestion)
Right answer, requested reference missingClass 3, PG II, but no 2.2.3.1.3 or 2.1.3.10Write the paragraph as you find it, before the answer
Reference incompleteA packing instruction given without its part, chapter, section and sub-sectionGive the full number, e.g. 4.1.4.1 P001, as the reports show
Steps skippedStating the precedence result without the two classifications that lead to itOne line per step, as in the GOV.UK worked examples
Question not fully answeredAnswering one part of a two-part question, or as if the vehicle carried only one loadUnderline each thing the question asks for before you write

These are easy to miss when you mark your own practice against an answer you only partly remember. The DfT review recorded “longstanding complaints regarding the limited feedback that DGSAs receive on their exams”; it adds that the DVSA has since increased the feedback candidates receive, and that the Department will await feedback on those improvements before making further changes. The three sample papers come without answers. A practice mark is only as useful as the marking behind it: mark against the exact words of the regulation, point by point, and count a point only if your answer states it.

Handwritten, and likely to stay so for now

In the same review 56 % of the 268 DGSAs said they would prefer to take the exam on a computer and 44 % by hand. The Department said further research is needed on a switch, including accessibility. For now, practise writing answers by hand against the clock: references and steps take longer to write than to think.

Planning around the numbers

IfThen (our suggestion)
You sit all three togetherGive Road the most time: it has had the lowest pass rate in most sittings
You fail one paperYou pay for that subject again (£135). Results can take up to 8 weeks, so check the next application deadline as soon as you hear
You are renewingSit early in the final year of your certificate: a failed paper then still leaves at least one more sitting

Dates and deadlines are in our dates and booking guide.

Frequently asked questions

What is the DGSA pass mark?

The GOV.UK syllabus says 65 % for each paper. The official sample papers say you need 32 marks out of 50 to pass. 65 % of 50 is 32.5.

What is the DGSA pass rate?

In March 2025 the national pass rates were 78 % for Core, 62.9 % for All Classes and 51.5 % for Road. Across March 2019 to November 2023 they were 79 %, 66 % and 60 %. Those are rates per paper, not the share of people who qualify.

Which DGSA paper has the lowest pass rate?

Usually Road. It was below Core at every sitting from 2019 to March 2025, and the lowest of the three in four of the five sittings from March 2024 to March 2025; in September 2024 All Classes was lower.

Is the DGSA exam hard?

Roughly a third of All Classes candidates and two in five Road candidates did not pass in 2019 to 2023. The papers are open book but written, and examiners report many marks lost to missing or incomplete references, so knowing where to find a rule matters as much as knowing it.

Why are the Rail and Inland Waterways pass rates different?

The sources give no reason. These modes have relatively few certificate holders (14 Rail-only, 52 Road and Rail and 15 Inland Waterways in February 2024), but entry numbers are not published, so how much one candidate moves a rate cannot be said.

Are there DGSA pass rates for 2025 and 2026?

The latest official figures we found are in the SQA’s March 2025 candidate performance report.
