At this time, there are few readily available tests that measure aural structure abilities in lower-level ESL classes in adult or high school. In the past two years, however, the Ilyin Oral Interview (Newbury House, 1972,76) has been successfully adapted from its one-to-one format to a mass listening test. It is being used in San Francisco Bay Area adult programs for achievement testing, and has been used in a summer program for placement purposes. Although the aural test format is soon to be published, it is possible for interested persons to adapt it for themselves from the published Ilyin Oral Interview. (The publisher has already promised permission to duplicate Interview material on written request.) This paper gives detailed instructions for adapting and administering the mass listening test.
