Tree Risk Management & Assessment Training

What's in it for you?

Tree risk management and assessment can be really challenging and confusing, can’t it? Well, the great news is it needn’t be.

We've done the hard work for you
First, you get a Tree Risk-Benefit Management Strategy. Not only has the Strategy got your back, because it Speaks Truth to Power. Your Strategy does more than 95% of your risk assessments for you!

We've modelled the risk with an internationally distinguished Professor of risk in the natural environment. This drives the Tree Risk App, and underpins the Strategy risk ratings.

If all that wasn't enough. We've taken out the bafflegab (vague words) and numberwang (difficult maths). So tree risk management and assessment is clear and easy to understand.

One thing you’re going to love about upgrading to VALID
Is how much more user-friendly you’ll find it.

Don't take our word for it. Have a look at what Validators are saying about how they feel. These are some words they typically use.


If you're an Arborist, we've got your back
When you've completed Validator training, you'll be able to carry out Active Assessment at a Basic, Detailed, and Advanced level. Your Validator Strategy has got your back because it Speaks Truth to Power. Both the Strategy and Tree Risk App do a lot of the heavy lifting for you and your clients.

Basic Validator (BV in the Calendar) training is for those who may not know that much about trees, but spend a lot of time working outside. Basic Validators carry out Passive Assessment by picking up on Obvious Tree Risk Features as they go about their day-to-day routines. They're a risk manager's greatest asset because they're most likely to pick up any red risks first.
