BERND KRAUSE,ISA Certified Arborist

I cannot speak highly enough of Dr. Vanderhoof’s ISA Arborist prep course. If you are looking to take your ISA exam soon I highly suggest enrolling in this course. The experience gained from it makes the actual exam a cakewalk. Thank you Dr. Vanderhoof for providing this course again! It was a great learning experience.read moreread less

FAQ

What is a learn-to-earn course?

In addition to our money-back guarantee, all of our courses are "learn to earn." That means the harder you work the greater your discount will be on your course fees. Each course is worth a total of 100 points. The number of points you earn will equal your refund in dollars. At Tall Tree Learning hard work really does pay!

Why is understanding time zones important for the live sessions?

Unlike other online ISA prep courses our live sessions occur in real-time, and you get to interact with a real, live instructor. That means the start times for the live sessions will be unique to your time zone. Don't worry though, you can enter the correct time zone in your course profile and all your assignment due dates and live-session start times will appear in your local time.

Am I really guaranteed to pass my ISA exam?

At Tall Tree Learning, we are so confident in our courses that we GUARANTEE you will pass your ISA exam! Our pass guarantee covers 100% of your purchase price. It does NOT include your testing fees, additional study materials, or other costs. To be eligible for a refund you must receive a passing grade in the course (76% or better), you must take your ISA exam no later than 60 days after the conclusion of the course, and you must provide proof of a failed test. Only one refund will be given per course purchase.
