This handbook documents assessment strategies that are in current use, have potential for duplication, or are in the testing and development stages, and that hold promise for more accurate assessment of limited English proficient (LEP) individuals in vocational programs. The handbook was developed as a result of a research and demonstration project funded by the Office of Vocational and Adult Education (ED) to assist in the implementation of the Carl D. Perkins Vocational and Applied Technology Education Act of 1990. The chapters in the handbook define and provide a rationale for different issues and strategies of assessment. After an analysis of the fundamentals of assessment and the forces that are expanding the concept of testing, specific techniques are explained with examples. The methods include the following: (1) interviews; (2) activities using the Cloze test format; (3) rating scales; (4) portfolios; and (5) projects. A chapter of fairer usage and clearer application of standardized tests is also included, along with a glossary and extensive references for each section. (Author/KC)
