Construction worker competency tracking: what to track and how

What competencies to track

The competencies you need to track fall into three categories:

National scheme cards

These are industry-wide certification schemes that most principal contractors require as a baseline. The major schemes in UK construction are CSCS (Construction Skills Certification Scheme), CPCS (Construction Plant Competence Scheme), CISRS (Construction Industry Scaffolders Record Scheme), ECS (Electrotechnical Certification Scheme), EUSR (Energy and Utility Skills Register), and Gas Safe. Each scheme has its own card types, validity periods, and renewal processes.

Employer-specific competencies

Many principal contractors define competencies beyond the national schemes. These might include SMSTS (Site Management Safety Training Scheme), SSSTS (Site Supervisors Safety Training Scheme), first aid at work, fire marshal training, asbestos awareness, manual handling, or company-specific inductions.

Site-specific requirements

Individual sites may require additional competencies based on the work being carried out. A site with confined space work will require confined space entry training. A site adjacent to a railway will require PTS (Personal Track Safety) certification. These requirements change from site to site and must be managed at the site level. For a detailed breakdown of CSCS card types and what each one means, see our CSCS card management guide.

Industry schemes and card types

Each industry scheme has its own verification method:

• CSCS: Verified via the CSCS Smart Check tool (app or website). Over 2.3 million cards verifiable. Card number and date of birth required. For a full list of card types, see our CSCS card types guide.
• EUSR: Verified via the EUSR online register. Registration number, surname, and date of birth required.
• Gas Safe: Verified via the Gas Safe Register website. Licence number required. The register shows which gas work categories the engineer is qualified for.
• CPCS: Verified via the CSCS Smart Check tool (CPCS is part of the CSCS scheme). Card number and date of birth required.
• CISRS: Verified via the CISRS online register. Card number required.
• ECS: Verified via the ECS online register or the JIB (Joint Industry Board) website.

Manual verification of each card for each worker on each site is time-consuming. On a site with 200 workers across 15 subcontractors, you could be looking at 1,000 or more individual cards and certificates to verify and track.

Confidence scoring

Not all competency records are created equal. A CSCS card verified directly through the CSCS API is more reliable than a card number typed into a spreadsheet by an admin. A certificate uploaded by the worker is more reliable than a verbal claim with no documentation.

Confidence scoring is a system for grading the reliability of each competency record based on how it was created and verified. AttendIQ uses a six-level confidence scale:

• C6 (Verified): Confirmed directly via the issuing body's API (CSCS Smart Check, EUSR register, Gas Safe register). The highest level of confidence. Also assigned to certificates uploaded by the worker themselves, on the basis that a worker is the most reliable source for their own qualifications.
• C5 (PC API): Data received via an API integration with the principal contractor's ERP or HR system.
• C4 (PC Admin): Entered manually by a principal contractor admin, or imported via CSV.
• C3 (SC API): Data received via an API integration with a subcontractor's system.
• C2 (SC Admin): Entered manually by a subcontractor admin.
• C1 (Unverified): The lowest confidence level. Claimed but not yet supported by documentation or verification.

Confidence scores are assigned automatically by the system based on the source of the data. They cannot be manually overridden. This prevents the common problem where an admin "upgrades" a claimed competency to verified status without actually checking it.

When you define access rules for a site, you can specify minimum confidence levels. For example: "CSCS card required at confidence C4 or above." This means a worker whose CSCS card has been entered by a PC admin or verified via the API will pass, but a worker whose card was only claimed verbally (C1) will not.

Automated expiry alerts

Most competency cards and certificates have expiry dates. CSCS cards expire after five years. First aid certificates expire after three years. SMSTS certificates expire after five years. Asbestos awareness training should be refreshed annually.

Tracking these expiry dates manually across a workforce of hundreds of workers is where most competency management systems fail. The data exists, but nobody is actively monitoring it. A card expires, and nobody notices until the worker is at the gate.

Automated alerts solve this by sending notifications at defined intervals before expiry. A typical configuration:

• 90 days before expiry: email to the worker's employer. Enough time to schedule the renewal.
• 30 days before expiry: email and push notification to the employer and the worker. Final warning.
• On expiry: the competency is marked as expired. If the competency is required by a site access rule, the worker is blocked from signing in.

This shifts competency management from reactive (discovering problems at the gate) to proactive (preventing problems before they occur).

Linking competencies to access rules

Competency tracking is most powerful when it is connected to site access. Rather than checking competencies as a separate administrative process, you can define access rules that include competency requirements. When a worker tries to sign in to site, the system checks their competencies automatically.

For example, a site might have the following access rules:

• Valid CSCS card (minimum C4 confidence) - required for all workers
• Site induction completed - required for all workers
• CPCS card for plant operators - required for anyone assigned to a plant operator role
• Asbestos awareness - required for all workers in Building A (where asbestos has been identified)
• Confined space training - required for workers assigned to the basement works package

When a worker signs in, the system evaluates all applicable rules and returns all failures at once. A worker who is missing both their CSCS card and their site induction is told about both problems in a single response, not sent away to fix one and then blocked again by the other. This approach is described in our pricing overview, which covers the compliance features included at each plan level.

Tracking across subcontractors

On a multi-contractor site, the principal contractor needs visibility of competencies across all employers. The traditional approach is to ask each subcontractor to submit a spreadsheet of their workers' qualifications before mobilisation. These spreadsheets are typically out of date by the time they arrive, and there is no mechanism for keeping them current.

A better approach is to give subcontractors access to a shared platform where they manage their own workers' competency records. The subcontractor enters or uploads the data, and the principal contractor sees a real-time compliance view across all subcontractors. Expiry alerts are sent to the subcontractor admin, not just the principal contractor. This distributes the administrative burden while maintaining central visibility.

AttendIQ provides this model. Subcontractors join the platform at no cost and manage their workers' competency records in a portal scoped to their company. The principal contractor sees a unified view across all subcontractors, filterable by compliance status, by competency type, or by expiry date.

Building your competency library

The first step in setting up competency tracking is defining your competency library: the master list of all qualifications, certifications, and training that your organisation recognises and tracks. A well-structured library typically has three tiers:

1. National scheme competencies: CSCS, CPCS, CISRS, ECS, EUSR, Gas Safe. These are standard across the industry and should be included in every library.
2. Employer-level competencies: SMSTS, SSSTS, first aid, fire marshal, manual handling, asbestos awareness. These are common across all your sites.
3. Site-specific competencies: PTS, confined space, specific plant types, site-specific inductions. These are added at the site level and only apply to workers on that site.

Each competency in the library should have a defined validity period, a renewal process, and a minimum confidence level for acceptance. This metadata drives the automated alerts and access rule checks.

Building the library takes a few hours of initial setup. Once defined, it applies across all your sites and all your subcontractors. New sites inherit the national and employer-level competencies automatically and only need site-specific additions.
