About the Course

This three day integrated training and assessment programme is aimed at the experienced arborist or tree work professional, who already has the knowledge and skills to identify and diagnose potential problems, recommend and prioritise appropriate treatments and work programmes. The course is designed to help candidates recognise hazardous trees as part of their main duties and then implement control measures in a specified and appropriate timescale. The training consists of classroom and practical activities with an exam on the final day.
