The process of revising and validating two English language tests used by the United States armed forces in hiring foreign nationals overseas is described. Development of the item banks and classification of items are outlined, and field testing in the United States and overseas is described. The tests were the basic and intermediate level language skills measures. The basic-level test's format and content were retained, but the number of items in each subtest was increased. The intermediate-level test was revised to include multiple-choice subtests for reading, writing, and listening and an oral interview. Field testing consisted of administration of both the original and the revised versions and comparison of results. High correlations were found between the revised tests and the original tests and other measures of validity. Use of the revised versions in place of the originals is recommended. (MSE)
