Norms for Air Force technical training materials were developed for seven previously developed structure-of-intellect and seven psycholinguistically oriented variables which have been used to assess the readability/comprehensibility of textual materials. Separate norms are presented for Air Force study guides, manuals, career development course materials, and technical orders. An "overall" norm is also presented along with norms on the same variables for a small sample of general literature. A multiple linear regression equation, which relates the various comprehensibility measures to measured comprehensibility, was developed and cross-validated. (Author)
