The second in a series of manuals on adults with learning disabilities, the booklet covers assessment techniques. The nature of assessment as an ongoing process is stressed, and the role of observation (both systematic and nonsystematic) and interview data are discussed. A seven-step evaluation sequence is proposed, with the major goal of interpreting the error patterns which will indicate processing strengths and weaknesses. The importance of the interview between adult education teacher and adult student is pointed out, and guidelines are suggested for structuring the interview environment. The contribution of adult education teachers to evaluation of cognitive functioning is noted. Specific measures for assessing general cognitive ability, language, academic achievement, written expression, and personality are listed. Two bibliographies are appended--one on neurological assessments, screening and placement, and prevailing assessment strategies; and one on general background information for adult education teachers encountering a learning disabled student.
