The information in this guide should help speech and language pathologists and others who are responsible for the assessment of students from the target populations, African Americans and Hmong students in Wisconsin. The guide provides information pertaining to cultural factors influencing learning and language and recommended procedures for complete and appropriate unbiased assessment. It contains data collected as a result of language analysis samples of typically developing Hmong and African American children, noting dialectical and phonological patterns that should not be considered errors. Some intervention strategies are presented for regular education teachers, and case studies illustrate the issues discussed. The guide contains these chapters: (1) "Perspectives: Ethical, Historical, Legal, and Demographic"; (2) "Cultural Considerations"; (3) "Assessment"; (4) "Language Sample Analysis" (5) "Narrative Discourse Analysis"; (6) "Intervention"; (7) "Case Studies"; and (8) "Appendixes." Twenty appendixes contain supplemental information about specific issues, some sample forms for student evaluation, and glossaries. Each chapter contains references. (Contains 17 figures.) (SLD)
