Level 4 Diploma in Construction Site Supervision – Retrofit

Level 4 NVQ Diploma in Construction Site Supervision – Retrofit is for you if you’re already supervising work on site and you need a recognised NVQ to confirm your competence. You may be working in a formal supervisor role, or you may have recently stepped up and be acting as a supervisor.

To complete the qualification, you’ll need to be able to show that your role includes the following:

  • You must be supervising work on site.

Your assessment is based on the work you already do on site. There are no exams, no classroom tasks, and no scenarios that don’t reflect real site conditions.

  • Portfolio of evidence.
  • Workplace observations.
  • Professional discussions.
  • Photos, site documents, and records.

Your assessor will support you throughout the process, helping you understand what evidence is needed, how to collect it, and when it should be submitted.

The aim is to keep assessment practical, clear, and achievable alongside full-time work
