FOIA is the freedom of information act. It can be applied to anything.
PRIA contains: enforcement actions, performance from air carriers in which you fill out PRIA requests for and a NDR.
The NDR only contains your name if you have serious driving offenses. (Not speeding tickets) State DOL/DMV records contain speeding tickets etc.
FOIA can access all FAA airman files and complete history of commercial checkride failures.
Someone correct me if I am wrong but...
PRIA only discloses checkride failures from past 5/10 years (of which you fill out the forms prior to employment) and from the FAA side only contain enforcement actions and checkride failures after 2006.

And again....always disclose everything.
