These are real pages from the book. The table of contents is the full one: 11 parts and 62 topics.
You've read the part on scientific names three times. You close the study guide...
...and you can't remember which word is the genus, which is the species, or where 'October Glory' goes. It was just one line after another.
Here, scientific names are one page of boxes: Acer rubrum split into genus and species, Quercus alba next to it, and the cultivar 'October Glory' in its own box, in quotes.
And on the pages next to it, every topic gets its own: twigs and buds, leaf arrangement, silhouettes, keys and field guides, and right tree, right place.
First you understand why it's written that way. Then the order sticks on its own.
The exam, tree biology, identification, soils and installation, pruning, diagnosis, construction, tree risk, safe work practices, urban forestry and a final review: 66 pages, all drawn
What if every topic fit on a single page?
Instead of rereading half a page about the root system without being able to see it...
...you open the page and find the root flare, the structural roots, the absorbing roots, the root cap and mycorrhizae drawn on one tree, each with its job.
And CODIT, soil horizons, pruning cuts, tree risk and electrical approach distances turn into drawings and tables you can read at a glance.
You stop repeating and start understanding.
That's exactly what The Certified Arborist Sketchbook does. It's not “just another manual.” It's 11 parts and 62 drawn topics, and at the end the frequent mix-ups, the key numbers and an exam day checklist. Because what your brain sees in order, it remembers.
Because what your brain sees organized, it remembers.
Walk in knowing the format: 200 questions, 210 minutes, the 10 domains and their weights, eligibility, scheduling, scoring, retakes and recertification.
Roots, trunk, branch and leaf anatomy, photosynthesis, water movement, CODIT and how trees respond and grow.
Scientific names, twigs and buds, leaves, flowers and silhouettes, keys and field guides, and right tree, right place.
Soil texture and horizons, pH and nutrients, drainage, urban soils, nursery stock, planting depth, the root flare and young tree care.
Pruning standards and objectives, the branch collar, removal, reduction and heading cuts, the three-cut method and what not to do.
Signs and symptoms, biotic and abiotic causes, insects and mites, the disease cycle, stress and Plant Health Care.
The four construction phases, tree protection zones, root and soil damage, fencing and treating damaged trees.
Who decides and who assesses, the levels of assessment, targets, defects, cabling and bracing, and mitigation.
ANSI Z133, job briefings, electrical hazards, PPE, climbing systems and knots, rigging, felling, equipment and aerial rescue.
The benefits and value of urban trees, ordinances and tree protection laws, and inventories and management plans.
The frequent mix-ups, the key numbers to remember and an exam day checklist.
At the end of the book: Frequent mix-ups, key numbers and an exam day checklist.
Correct and incorrect cuts side by side (branch removal, reduction, heading, flush, stub), each with a tiny sketch, so you can spot the wrong cut in a second. Printable for the truck or your desk.
Term on the front, a one-line definition and a tiny sketch on the back: review vocabulary in short sessions between jobs and fix frequent mix-ups before exam day.

The ISA Certified Arborist Program Guide (revised August 2025) and the Examination Outline (Job Task Analysis 2022), cross-checked with OSHA 29 CFR 1910.333, ISA's treesaregood.org and Iowa State and Penn State Extension. Where a number isn't verified, the page tells you which official reference to check.
No. It's an independent study aid, not affiliated with or endorsed by ISA, ANSI or TCIA. It doesn't copy the official study guide, exam questions or standards text. Buying it doesn't give you a certificate or CEUs and doesn't register you for the exam: you apply and schedule through ISA.
No. It's a drawn review to keep at hand alongside the official study guide, your training and your field experience.
No. The book itself is a drawn review, and the two bonus books are field sheets and term cards. Practice questions come only in the optional Certified Arborist Practice Sets offered at checkout: 200 original questions written for this series and explained, not official questions from any exam.
Yes. The PDFs are high resolution, so you can print the whole book or only the pages you want for the truck or your desk.
