I am currently studying for my CISSP and I am well aware of the experience requirements.
I know that it does require a 4 years degree to qualify for the one year experience waiver. But I assume it is just just to stop people with an 'Associates' degree in the US from waiving a year (after just studying a year I think???).
I have a Bachelor's Degree in Information Assurance & Security which took me 3 years (as is the case with Bachelor's degrees here in New Zealand, just like Computer Science).
Is this fine to satisfy the 1 year experience waiver or is it strictly a 4 year qualification?
The eligibility requirement for a Bachelor's degree replacing a year of experience is just that. Someone who crushed out all their summer semesters could complete a Bachelor's in three years in the U.S. too. As long as the institution granting the degree is accredited, there are no issues. Simply put, a Bachelor's is a Bachelor's.
