Different than some countries with the nationalized curriculum (like Japan), international schools are independently operated and fall under the jurisdiction of a variety of accrediting agencies. NIS is accredited by both CIS and WASC and is also an "IB World School" providing the PYP and Diploma Programme. While these agencies have certain guidelines and policies, ultimately it is the school, which must develop the appropriate curriculum for both the needs of our community and the standards of those organizations, and this is typical of most international schools around the world.
