Running a tree crew for a county, city, town or township? The page for public crews covers quotes, W-9s and purchase orders.
Why train everybody
The standard covers the whole crew, not just the climber.
Most of it is work done from the ground
Feeding the chipper, clearing the drop zone, setting up traffic control, standing near a truck that may be touching a line. Z133 covers all of it, and none of it is climbing. Training only the climber leaves most of the standard with nobody.
The experienced hands get current
Z133 was revised in 2026. The 2017 edition recognized three levels of electrical qualification, and the 2026 edition recognizes four. Fifteen years on the job is real knowledge, but it does not update itself when the standard does.
A new hire starts from the standard
In their first week, somebody new learns the job from whoever is standing nearest. With this, they start from the same rules as everybody else on the crew. What they are ready to do is still yours to decide, once you have watched them work.
The standard is free. Learning it is the hard part
ANSI Z133 applies whether or not anybody on the crew has read it, and anyone can download it. But it is 104 pages written to be looked up rather than learned. This course teaches it start to finish.
The risk is on the record
Deaths, injuries and OSHA citations in US tree care are published by federal agencies. The data page collects them, dated and sourced, so you can weigh the risk from the record rather than from us.
In our view, the outfits that run safest are usually the ones that run best. Nobody is above the standard, the owner included.
How it fits the work
No class to schedule and no trainer to book.
The course is 50 lessons, and it picks up where each person left off. That can be an hour at the end of a day or a rain day, rather than a whole day with the crew off the job.
Nobody travels. A new hire can start it the week they start with you, rather than waiting for the next class to come around.
What the certificate is
A record of training that anyone can check.
When somebody passes, the certificate says they completed the full course of instruction and passed the final assessment for a course built on ANSI Z133-2026. It carries their name, the date it was issued, the date it expires two years later, and a code, also printed as a QR code. Anyone can check that code on this site without an account.
It does not certify competence. It is not a license, a credential, an accreditation or a legal shield. What the record is worth to you is yours to judge.
How buying works
A price for the whole crew, arranged with a person.
Tell us how many people and we will price the course for all of them, below what each would pay alone. It is arranged with us directly, not through the site. There is no cart, no team account and no employer dashboard.
Each person takes the course on their own account, because the certificate names them and runs on their own two-year clock.
An employer view, where you buy for the crew at once and see who has finished, gets built when enough crews ask for it. It has no date. The form below is how we count.
