Here is Senator Testor’s Report, which was filed on October 1, 2014. The Report has a great overview of language programs. An excerpt:
The Committee on Indian Affairs, to which was referred the bill
(S. 1948) to promote the academic achievement of American Indian,
Alaska Native, and Native Hawaiian Children with the establishment
of a Native American language grant program, having considered
the same, reports favorably thereon with an amendment and
recommends that the bill, as amended, do pass.
