CTEC or CTREC? One is generic, the other is a company.
As a former Microsoft Certified Trainer, all I can say is go for it. Be careful about the repayment schedule though.
The other thing is to find out how many hours per week you will work. Alot of the training companies might only work you for 2-4 hours per week, depending on how many classes they have etc. If they have the classes scheduled, and guarantee you 40 hours per week, then it sounds like a good deal.
Figure the company charges $1500 per 40 hour class. They put 15 students in each class, and they pay you $25 per hour (I made $40 back before trainers were a dime a dozen). They make $22,500 per class and pay you $1000.. not rocket science to see they are doing just fine.
