Installers can now complete the full route towards becoming a 3M Endorsed DI-NOC Installer through the William Smith Training Academy.
In addition to our established two-day 3M DI-NOC Application Training Course, we will now host official one-day Endorsed Installer Assessment days at our Barnard Castle facility.
This makes progressing from training to assessment easier than ever. Trainees can develop their knowledge and practical skills with our experienced team before completing the assessment through William Smith, without needing to arrange it separately with 3M.
A Clearer Route to 3M Endorsement
The new assessment days create a straightforward three-day route for installers working towards 3M endorsement:
- Two days of practical 3M DI-NOC application training
- One day completing the official written and practical assessment
The two-day course provides the preparation installers need before attempting the assessment. It allows trainees to learn the correct application methods, practise the required techniques and receive guidance from an experienced trainer.
Following this training route puts each installer in the best possible position to demonstrate their skills during the assessment and work towards becoming 3M endorsed.
