Professional Tree Inspection

~3.0 Day(s)
From £599.00
A 3 day preparation course for the Professional Tree Examination, this will demonstrate your competence to carry out tree surveys and make recommendations for effective and appropriate tree management.


The course

This is an intensive 3-day short preparation course for the Professional Tree Inspection examination. The integrated training and assessment programme is aimed at helping those who already have the skills and knowledge 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 the control measures in a specified and appropriate timescale. It aims to confirm the competence of a professional arboriculturist, and their part in a defensible tree management system.

Entry Requirements

Aimed at those who already hold a Level 3 or higher national qualification, such as a National Diploma in Arboriculture or studying towards a higher-level qualification. As an experienced and qualified arborist with in depth knowledge of plant and arboricultural tree surveys. It requires extensive previous knowledge, and the ability to study written technical information and experience in surveying trees.

We expect that you will have a detailed pre-existing knowledge of tree biology, the tree as an undamaged self-optimised structure, biological and mechanical weaknesses, pathology, legislation, remedial options and their likely implications and the British Standard 3998 Recommendations for Treework.


This is an integrated training and assessment course. There will be a written question paper, fungi identification and a practical tree inspection.

At the end of the course candidates will carry out an assessed tree inspection.
