The schedule outlines the specific commitments each country makes in a given sector and lists any conditions on that commitment. A country only has a commitment if it lists that sector in its schedule and lists any relevant restrictions that apply in its market access or national treatment column. Note again that regardless of the restrictions listed for market access and national treatment, MFN treatment should still be guaranteed to foreign service suppliers, unless a country has specifically exempted that sector and included it in its MFN exemption list. The first column in a GATS schedule lists the general or specific service sector under which commitments are made. Countries can schedule all sectors or just certain subsectors for which they wish to make commitments.
Countries are free to limit or broaden the scope of a sector.
The second column is for listing market access limitations for a given mode of supply. Restrictions listed here will be maintained by the country. If a restriction is not listed, the country must provide full market access. The third column is for listing any limitations on national treatment. In general, national treatment requires that a service supplier from another member country be treated no less favorably than service suppliers from the host country.
