I've got a few Franklies that come to mind too, having just wrote a big topic on this subject yesterday.
The test may not be real hard, but Frankly, there are still quite a few people who don't pass the test.
The test may not be real hard, but Frankly, in no way does it stop a homeowner from expecting even more.
The test may not be real hard, but Frankly, I've seen a couple of folks with Masters degrees who were less skilled in the field.
The test may not be real hard, but Frankly, it can't be taken and passed with no experience of any kind.
I suppose it would be nice if the test covered more territory, but on the other hand, it would be unrealistic to expect a rather new certification program to be on par with other professions like medical or electrical that have had much more time to develop systems for qualification.
The point is, the Certified Arborist system is slowly improving, and is better than doing nothing. It can be incrementally added to just the way that virtually every other profession did.
It's basically "acclimatizing" a profession to testing. To dump 4 times the testing on arborists right now, would be as harsh as taking a greenhouse shrub from Washington, and planting it in the middle of Ontario, Canada.
