Frankly, it's confusing. I chose a course based on the fact that I planned to use it in a clinical setting, I couldn't take off work to travel somewhere and study for any length of time, the price was affordable and the author had a Ph.D. in Chemistry, which I thought was vital to what I needed. Like most people, however, I agonized over whether a more expensive course would give me more ... or make me seem more professional. Truthfully, I still don't know the answer but I suspect it depends a great deal on the person choosing and her learning capabilities. That makes it infinitely more questionable doesn't it, because I'm sure everyone who signs up for a course feels like he/she is pretty smart and perfectly capable of understanding everything presented.
I came away from my course feeling like I was a step ahead of the average person claiming to know something about essential oils and although I still think that's true, I've learned so much since then that's altered what I originally understood that I wonder if it was possible to have learned all the basics in any aromatherapy course or school. It really takes the hands-on work on a regular basis to appreciate many of the things you learn from the books and my personal opinion is that no one truly knows an essential oil until they've worked with it extensively.
So does there need to be more management of the schools or is it sort of like choosing between university and community college? Either way you come away with an education, right? I'd love to hear opinions from other practicing aromatherapists on the issue of schools and what constitutes good training.
