I know ECP. I like their program. I dont know what kind of expertise people expect to achieve with a 100ish hour class, but it is very simple.
You get a textbook.
you get a workbook
you get the state protocols
you get the CPR book
you get a student guide
they expect you to read the whole textbook, and do all the work in the workbook.
they epxect you to read the CPR book, and memorize the figures.
they will test you first on the written CPR exam
then they will test you on the CPR practical exam.
if you pass you become CPR certified, if you fail you cannot continue the class.
CPR cert is the one for health care providers,
then they continue with the rest of the stuff, lectures and practical skills.
they teach you the NY specific stuff. which differs from the textbook.
you get alot of hands on training for everything you need to know..
control bleeding, splinting, stair chair stretchers and boards, airways, drugs, childbirth, ambulance operations, ppe and pediatrics all that stuff...
you will also learn too much about anatomy and the human heart.
you will be tested with the state practical exam, and you will be taking a state written exam.
I think all course providers must follow the curicculum as specified by some authority somewhere, as if it is almost all the same.
I will say to be sure to read the book at home... that is the most important part of understanding the class. good luck.
