Master's + some experience would qualify for EB2 but Associate + 5 yrs of exp will definitely go for EB3. Bachelor's + 3 yrs of exp would challenge for EB2 if not EB3 (safe is BAchelors + 5 yrs).  In overall if that's the job requirement, then DOL will list it in EB3 row because of present of Associate + 5 yrs.
