ASPE is primarily a seminar marketing organization -- they do not specialize in testing and offer courses in a variety of other unrelated fields.
Many or most of the test seminars are being taught by Jim York, who is an experienced tester and trainer and who has taught at least a couple of hundred of testing seminars. I hear that he is receiving very good to excellent evaluations. A few other experienced test trainers also are involved.
They are using materials developed by me, for which I am paid a royalty.
My name is Chris Hollingsworth and I can answer any other questions you may have about ASPE. We actually focus on 100% of our time on Technology Training Topics and have a curriculum of 5 courses that support the QA & Testing process.
