Here's a re-print of my old take on the different types of trainers and training situations that you might find ( and my view on what to look for or avoid in determining if a trainer is worth using) :

The types of training classes:
Most common that I see is an actual chartered obedience club ( Aligned with the AKC and can hold sanctioned trials and matches ) or the ob portion of a breed or kennel club. In these classes the instructors are volunteers and the quality varied greatly. Some times you get a good, knowledgeable trainer, but sometimes you get a club member that may not have much experience and doesn't really know what they're doing.
You have two types of students in these classes - club members that working a competition dog up through the ranks, and the non-club members that have paid for the class.
Classes run by "Pet Shop" or the branches usually suck. The instructors are usually marginal at best, and they're under the thumb of the store, so they're hamstringed in how they can even teach. Plus the class is usually full of unmotivated students being trained in a 15' x 20' area, way too small to be even able to heel.
Classes held at professional kennel sites - these tend to be more serious classes ( and *far* more expensive ) and unfortunately also range widely in trainer experience and instructional skill. You can train with hard-core top level instructors ( for beginning classes you're usually going to be trained by the assistant ) and for someone serious about training, these can be the best choice if you get the right instructor.
Now, this is just my opinion, but it doesn't hurt to ask the instructors what their experience is and what their training philosophy is.
An instructor for the AKC ob clubs should at least have a few CD titles under their belt as a minimum, and a UD or two is a sign that the instructor is at least a serious competitor, which usually translates into being a better instructor.
For the Pet Smart type instructors, don't bother, the odds of them having a title or competing is slim-to-none.
For the Kennel site/ Professionals - now *here* is where you should be asking to *see* their titles, and trophies, etc, etc. There are *far* too many "trainers" with a slick website and a lot of self-promotion that actually have no real experience in dog training. And these are not the people that you should be handing over your hard earned money to.
Also, if you're headed to a professional, ask him to show you the training on his dog - this is an excellent way to see what the instructor is capable of ( of course, you'll ask to make sure that the trainer actually trained the dog and didn't buy him already titled, right? ) and how he interacts with the dog. A instructor's dog should look sharp and willing and like a dog that you'd want to own.
Ok, to me these are warning signs that you're not probably not getting a good instructor:
They don't own a dog or have one as a demonstration dog.
They've never titled a dog in any legitimate dog sport.
They have the "APDT" or the "CPT" and other bogus pet training certifications plastered on their website ( but oddly..they have no titles... )
They have their "AKC Canine Good Citizenship Evaluator" number all over their site ( which doesn't require any training experience to get )
They'll always have the token "after a lifetime of dog ownership, trainer Joe Blow has turned that experience into...." ( well, the turned that "experience" into no titles, apparently... )
They have photo's of all the Football players and movie stars who have bought dogs from them ( so those type of owners are expert judges of dog training? Didn't think so.... )
Have their "Master Dog trainer" title boldly displayed ( ask them from where - if it was any place besides the Tom Rose School or Triple Crown Academy, then that title doesn't mean spit )
Make the claims like "has trained 8000 dogs in a 17 year period ( taken from an actual site ) Do the math - that's 470 dogs a year. That is a totally BS claim with no basis in reality, sorry.
Feels the need to note how many books that they've read on dog training ( if a trainer is so desperate to pad their claims that they're stuck telling you about the number of books that they've read about training, you and your dog are in trouble )
Have training or protection video's on their website that are just plain bad. If that's the best they can do and they're willing to put it on the internet for everyone to see, what are they going to do with *your* dog?
All this is just my opinion,but I've seen this stuff in real life soooo long that I'm getting hard to fool now.
And I don't want ya'll fooled either!
Please, you're entrusting your dog and your cash to these people, start using a critical eye and ask *questions* before you take the step!
