Frequent Questions

When must a system implement Data Standards?

All Agency information systems that exchange information shall implement applicable data standards in the most current version at the appropriate phase in the development life cycle but no later than the required implementation date specified in the standard unless a waiver has been obtained. When a new version of a standard is issued, the old version is given a retirement date and should not be used after that date.
