Safety Culture Ladder level 3: calculative

Level 3 on the Safety Culture Ladder is the calculative level: the systems and procedures for safety are in order, but safety is mainly directed from above and is not yet part of everyday life for everyone on the shop floor. NEN describes it as “the focus is on systems, but not on implementation on the shop floor”. It is the middle of the five levels of the Safety Culture Ladder.

Level 3 is the level that most companies need. Since July 2026, level 3 is the minimum requirement within ViA, the tender agreement of the Governance Code Veiligheid in de Bouw . ProRail  also requires at least level 3 from contractors. Below, you can read what level 3 looks like in practice and what the auditor wants to see.

Characteristics of Safety Culture Ladder level 3

The official NEN description  describes a calculative culture with these characteristics:

Characteristic (NEN)What it means in practice
A lot of attention to safety management systems and overviewsRI&E, TRAs, inspections and records exist and are kept up to date
A strong emphasis on information and dataDashboards with incident figures, IF and inspection counts
”Because it is well arranged on paper, the organisation believes it works safely”Trust in the system rather than in behaviour
Mainly managers are involved in safety and complianceEmployees follow, but think along little
(Near) accidents and unsafe situations are not always reportedReporting feels like a hassle or a risk
Changes are mainly new or stricter rulesAfter an incident, an extra procedure follows

Important to know: level 3 is not a “pass” in the sense of a final level. It is an organisation that has arranged safety well. The next step, level 4, is about whether people want to do it themselves.

What does a level 3 company sound like?

WhoStatementWhat it reveals
Director”Our IF has fallen this year, and all toolbox talks have been held.”Steering on figures
KAM coordinator”It is in the procedure, so everyone knows it.”Trust in paper
Site manager”I check whether they do it, otherwise I address them.”Compliance through supervision
Fitter”I follow the rules, they are there for a reason. But thinking along is for the KAM department.”Following, not ownership
Fitter”Reporting a near miss? Then I have to fill in another form.”Reporting is a barrier

An example. An installation company with VCA** has everything in order: TRAs, monthly inspections, toolbox talks. During the audit, a fitter says he fills in the LMRA card “because he has to”. At another location, the auditor sees a ladder without a base support, while the site manager has just left. Systems good, behaviour still dependent on supervision: that is level 3.

What does the auditor look for at level 3?

In a Safety Culture Ladder audit, two auditors hold interviews at all levels and observe on the workplace. They do not check whether your folders are complete, but how safety is experienced. Read more about the way of working on the audit process.

What the auditor examinesLevel 3 signal
Interview with the boardCan explain the safety policy and goals clearly, with figures
Interview with line managersKnow the procedures and actively steer on compliance
Interview with employeesKnow the rules and the reporting route, but do not always know what happens to their report
Workplace observationRules are mostly followed, especially when someone is supervising
Reports and analysesThe reporting system works and reports are analysed, but they mainly come from line managers
Improvement actionsStructured and followed up, often in the form of new rules

If you want to know what level 3 requires per theme, such as leadership or working with subcontractors, look at requirements per level.

Which clients require Safety Culture Ladder level 3?

Level 3 is the threshold for the largest clients in construction, infrastructure and rail.

Client or frameworkRequirementEvidence
ViA, clients who have signed the Governance CodeAt least level 3 from July 2026SCL Original, SCL or SCL Light
ProRail, recognised rail contractorsAt least level 3SCL Original certificate
ProRail, recognised engineering firmsAt least level 3 from 1 July 2026SCL certificate
ProRail, contractors and engineering firms not yet recognisedLevel 3 within 3 months of contract awardSCL certificate

The exact thresholds and conditions of ViA are on the page ViA requirement. Always check the tender documents of your client.

Which SCL product should you choose for level 3?

For level 3, you have three options. They differ in audit scope and in what you receive.

ProductFor whomResultHighest achievable level
SCL LightSmaller organisations (from 5 employees; separate variant for 5 to 50)StatementLevel 3
SCLFrom 5 employeesCertificateLevel 4
SCL OriginalFrom 5 employees, 100% audit every yearCertificateLevel 5

Do you want to move on to level 4 later? Then choose SCL or SCL Original, because SCL Light does not go beyond level 3. If your client explicitly requires SCL Original, as ProRail does for recognised rail contractors, you have no choice. Read more about the differences on the certification routes page.

The Approved Self Assessment does not count for ViA and does not give a level. For a level 3 requirement, you therefore need an audit by a certification body.

From level 2 to level 3: a quick check

Are you still at level 2? Then the systems to identify risks in advance are usually missing. Check these five points before you plan an audit:

QuestionYes/no
Is there a current safety policy that employees know?☐
Are risks assessed in advance for each project or task?☐
Do employees also report near misses, and are these analysed?☐
Do line managers visibly steer on compliance with agreements?☐
Are improvement actions followed up with an owner and a deadline?☐

Five yeses is a good sign. Confirm it with a baseline measurement in the SCL web tool and a gap analysis.

From level 3 to level 4: from rules to ownership

The step to level 4 is the hardest on the ladder. You already have the systems. Now safety must belong to everyone, not only to management. These are the shifts an auditor looks for.

From (level 3)To (level 4)Concrete action
Compliance through supervisionWorking safely without supervisionEmployees set the working agreements for their own tasks themselves
Reports come from line managersEveryone reports, and reporting is normalFeedback on every report within a week, and discuss good reports in the toolbox talk
After an incident, a new ruleAfter an incident, learn togetherDiscuss incidents with the crew: what do we learn, not who caused it
Management checksManagement asks for feedbackLine managers ask during site visits: “What makes your work unsafe?”
Safety as a separate topicSpeaking up to each other is normalTraining in speaking up, including towards line managers

Read what this requires in practice on the page Safety Culture Ladder level 4.

Frequently asked questions about Safety Culture Ladder level 3

Is level 3 enough?

For most tenders, yes: it is the ViA minimum. Some ProRail sectors, such as workplace security and cable and drilling companies, require level 4.

Can I reach level 3 with good procedures alone?

Procedures are the foundation, but the auditor talks to your people and looks at the workplace. If employees do not know the procedures or do not follow them, you will not reach level 3.

How long is a level 3 certificate valid?

Under SCL 2.0, a certificate is valid for three years, with follow-up audits in years 2 and 3. Your level can also go down at a follow-up audit.
