SQA code: GT27 79
Ofqual code: 603/7900/5
Total Qualification Time: 890
Guided Learning Hours: 387
Credit value: 89

The qualification will develop knowledge and skills in areas such as confirming work activities and resources for an occupational work area in the workplace. Learners can specialise in monitoring progress of work against schedules in the workplace.

This qualification covers the following areas:

  • confirming work activities and resources for an occupational work area in the workplace
  • developing and maintaining good occupational working relationships in the workplace
  • confirming the occupational method of work in the workplace
  • implementing and maintaining health, safety, environmental and welfare practices in the workplace
  • co-ordinating and organising work operations in the workplace
  • monitoring progress of work against schedules in the workplace

This qualification may be available through employers, training providers and colleges and may be offered in England and Wales.

The NVQ/SVQ in Occupational Work Supervision (OWS) was created in response to demand from industry for a progression route for team leaders and supervisors where there was no suitable vocational occupational or supervisory qualification available at level 3 (SCQF L6). It was also considered that the Construction Site Supervision N/SVQ was too broad in its scope and demand, and unachievable by specialist supervisors.

Following consultation with industry, it was clear that while the role carried out by a supervisor was common across a number of occupational areas, to operate effectively an occupational supervisor needed to be competent in the occupational area being supervised. This was to ensure they would bring knowledge and understanding of the specific working practices, quality standards, and health and safety requirements to exercise their duties effectively. It was therefore agreed that, where overarching supervisory qualifications such as OWS were used, it was on the proviso that awarding organisations verify:

  • the individual's experience and competence in their occupational area prior to being registered for the Occupational Work Supervision qualification.
  • the context (occupational area) in which the individual had completed their OWS qualification.
  • that the individual had the necessary occupational competence to supervise that occupational area.

New CSCS card requirements for S/NVQs in Construction

  • SVQ Occupational Work Supervision (Construction) SCQF L6 (GM3A 23)
  • NVQ Diploma Occupational Work Supervision (Construction) L3 (GE1Y 79)

As you will be aware, CITB SSC and CSCS have stipulated that for these two qualifications ‘learners must demonstrate relevant verifiable experience and competence in their occupational area’. This means that you must now provide details of the specific construction area (endorsement) that the learner was assessed in for their supervision competency.

OWS Endorsement List

This is a mandatory CSCS requirement. CSCS will not issue cards if this information is not provided with the CSCS card application.

Interim process from 15 April 2019 (applicable to Occupational Work Supervision only)

We have agreed an approach with CSCS to enable learners to receive their CSCS card in light of the new requirements.

CSCS have stipulated, that with immediate effect you must complete the attached ‘side letter’, detailing which endorsement (specific construction area) the learner has been assessed in, and submit this to CSCS along with any other documentation required to enable the learner to request their CSCS card.

The SVQ lapsed on 31 December 2019 and was replaced by GR0R 23.

The NVQ also lapsed on 31 December 2019 and was replaced by GR0H 79.

All other Construction S/NVQs with endorsement requirements

CITB SSC and CSCS have stipulated that all other CSCS cards must be issued with the relevant unit endorsement to show the piece of Plant, Equipment, Activity or Specialism that the learner has been assessed in.

This is a mandatory CSCS requirement. CSCS will not issue cards if this information is not provided with the CSCS card application.

Interim process from 1 June 2019 (all other Construction S/NVQs with endorsement requirements)

As an interim approach which is applicable from 1 June 2019, SQA and CSCS have agreed that centres should complete the 'side letter' attached. This should be submitted to CSCS along with any other documentation required by CSCS to provide the relevant card.

Please refer to the specific endorsement list attached to the qualification structure which is available on the CITB website.

From 1 January 2020

We are currently in discussions with CSCS to finalise the process for incorporating all endorsements into all S/NVQ's for implementation on 1 January 2020. We will provide further details in due course.

If you have any queries about the new requirements or changes to process, please contact construction@sqa.org.uk.

September 2021 update

  • SVQ in Occupational Work Supervision (Construction)
  • NVQ L3 Diploma in Occupational Work Supervision (Construction)

CITB SSC and the OWS National Working Group (NWG) have recently revised the S/NVQ Occupational Work Supervision qualifications.

As a result, there will no longer be a requirement for side letters or endorsements in the current S/NVQs. This decision means that:

  • awarding bodies will no longer be required to endorse an OWS qualification by the issuance of an endorsement or side letter to the award.
  • card schemes may no longer have a requirement to show endorsements on cards which should reduce the processes required to contain a card.

We have since gone through the reaccreditation process for the SVQ to remove the endorsement units. The qualification is now available under group award code: GT1N 23.

The NVQ L3 Diploma has also gone through the same process and is now available under group award code GR0H 79. Along with removing the endorsement units within the NVQ we have also created a new unit for Co-ordinating and Organising Work Operations in the Workplace (formerly FX8L 79) which now appears under code GT27 79. This unit was given a new code to reflect the updated NOS.

How to assess

Ongoing course assessment will apply. Each unit specification gives detailed information on the assessment criteria, assessment (evidence) requirements and guidance on instruments of assessment for the unit.

The qualification is assessed by completing a portfolio of evidence which details what the learner has completed at work. This can be gathered through observation, professional discussion, witness testimony or supporting documentary evidence. The assessor can work alongside the learner to confirm that they have met the requirements of the qualification and that they are therefore competent in their role.

Competence is displayed through the assessor observing the learner demonstrate that they carry out their normal work activities competently and to the industry standard and comply with current legislation and company procedures.

The assessment process will ensure that the learner can complete the tasks that they have been directed to undertake and that they can interpret the instructions correctly. They will demonstrate that they can select the appropriate resources for the tasks and can complete them within the given timescales and specifications.
