US Congress also heard (but ultimately ignored) unfavorable information about the Klamaths' readiness for termination. The 1954 Termination Act provided for a period of evaluation before termination would take effect in 1961. This evaluation led the Bureau of Indian Affairs to accord the Klamaths a "questionable status" as to their readiness, even though it had been the Bureau which had initially recommended the Klamaths for termination. In 1957, Congress were told that in the 1953/54 school year, 40% of Klamath students had failed to move up to the next grade; that two-thirds of able-bodied males do little or no work; and that a majority of the Indian population had been arrested at some point in their lives. Congress heard further testimony that although Klamaths had "shed the blanket" by abandoning outward Indian customs and dress, they hadn't "acquired the skills and attitudes necessary for the assumption of the responsibilities in a non-Indian society which they will be required to assume upon termination." The Klamath Education Program, designed to prepare Klamaths for termination, can only be viewed as hopelessly ineffective in their light of its own reports which reveal that up to 75% of Klamath Indians who enrolled for its vocational training programs failed to complete their courses.
