The Learning Efficiency Test-II (LET-II) is an expanded version of the LET (R. E. Webster, 1981), which is individually administered to persons with suspected learning difficulties or memory impairments. The norms have been expanded to include ages 5 through 75 years and older, with the norm tables in 1-year intervals between ages 5 and 15 years. The LET-II provides a reliable and valid evaluation of memory characteristics based on performance on visual and auditory memory test. Each modality test is comprised of six subtests measuring ordered and unordered recall, with varying types and degrees of verbal interference. The LET-II can be administered and scored in 10 to 20 minutes. Total summed raw scores can be used to compute standard scores for global memory, visual modality, and auditory modality. This manual contains directions for test administration and scoring, as well as educational and instructional remediation activities for use with persons showing information processing deficits on the LET-II. Five figures illustrate the text, and two case studies include six additional figures. Included are 54 pages of norms and 20 tables of validity and factor analysis data, as well as a 154-item list of references. A specimen set (test sample) is provided. (SLD)
