I won't say the test was easy but it is definately passable the first try. I read through the study guide and did the the study questions and the sample test questions. I have read a couple of Shigo's books and the ANSI publications. I had to read the questions carefully but with almost all of them I was able to immediately discard two of the four answers. The anxiety of taking the test was WAY worse than actually taking it. I encourage everyone that is serious about tree care to take it. If you really want to pass the test you will. Even if a couple sections give you trouble you can retake those sections within a couple of months for free.
It gives you a great deal of credibility when dealing with the public. I know there are a lot of people in our industry that aren't CA that have forgotten more about tree care than I will ever know. However, try and convince a client of that. It gives you an edge over a lot of your competition. I know, I've lost jobs simply because I wasn't a certified arborist. I can't even get in the door of several country clubs and golf courses in the area because I wasn't a CA. I'll let you know how I feel it benefits me in over the next few months.
Thanks for the congratulations, hopefully I can return them soon.
