"NEW SECTION.  Sec. 4   A new section is added to chapter 28A.320 RCW to read as follows:
     (1) Each school district board of directors is encouraged to incorporate curricula about the history, culture, and government of the nearest federally recognized Indian tribe or tribes, so that students learn about the unique heritage and experience of their closest neighbors. School districts near Washington's borders are encouraged to include federally recognized Indian tribes whose traditional lands and territories included parts of Washington, but who now reside in Oregon, Idaho, and British Columbia. School districts and tribes are encouraged to work together to develop such curricula.
     (2) As they conduct regularly scheduled reviews and revisions of their social studies and history curricula, school districts are encouraged to collaborate with any federally recognized Indian tribe within their district, and with neighboring Indian tribes, to incorporate expanded and improved curricular materials about Indian tribes, and to create programs of classroom and community cultural exchanges.
     (3) School districts are encouraged to collaborate with the office of the superintendent of public instruction on curricular areas regarding tribal government and history that are statewide in nature, such as the concept of tribal sovereignty and the history of federal policy towards federally recognized Indian tribes. The program of Indian education within the office of the superintendent of public instruction is encouraged to help local school districts identify federally recognized Indian tribes whose reservations are in whole or in part within the boundaries of the district and/or those that are nearest to the school district."
