The following may help you determine the basic difference between Preference Law and Reciprocal Preference:


  • Law is mandatory; is guided by statute, rule, statewide policy, executive order and is what gives you preference authority.
  • Preference is the subject of that law and can be either mandatory or discretionary.

Reciprocal preference

Reciprocal preference is a preference given based on residency. For example: Your state reciprocates a preference to a state that gives their resident bidders advantages over bidders from your state.
