They had a lab day where they bus you over to a paint shop and you get to sand blast, prime and paint your own test plates....and you also get to play inspector, so you get to put into practice all of the info that you were given. You get to use the whole gamma of test instruments and ask questions.....they also keep all of the testing equipment in the class room and you have the opportunity to get familiar with each piece after class each day for as long as you want. The instructors that taught our class were great, very much a "hands on" type of atmosphere. The (2) instructor's NACE CIP# was something in the low 30's....LOL, mine is CIP#14328 and I took the course in Mar/07...just to give you an idea of how long these guys have been certified themselves.
edit: I forgot to mention the log book....during the field trip to the shop to paint the test plates, you have an inspection log book to fill out and record your observations and testing figures in, the log book is part of your final grade and you must pass all 3 parts of the exam to become certified.
1) written exam
2) practical (hands on use of 7 pieces of testing/inspection equipment)
3) the log book(your entries in this book are critiqued and they look for several essential/required elements)
