This book documents the process the committee used to determinethese performance categories, estimates the percentages of adults whose literacyskills fall into each category, recommends ways to communicate about adults' literacyskills based on NAAL, and makes suggestions for ways to improve futureassessments of adult literacy.Table of ContentsFront MatterExecutive Summary1 Introduction2 Adult Literacy Assessments and Adult Education3 Developing Performance Levels for the National Adult Literacy Survey4 Determining Performance Levels for the National Assessment of Adult Literacy5 Developing Performance-Level Descriptions and Setting Cut Scores6 Communicating and Using the Results of Literacy Assessments7 Recommendations for Future Literacy AssessmentsReferencesAppendix A The Committee's Public Forums on Performance Levels for NAALAppendix B Examination of the Dimensionality of NALSAppendix C July 2004 Bookmark Standard-Setting Session with the 1992 NALS DataAppendix D September 2004 Bookmark Standard-Setting Session with the 2003 NAAL DataAppendix E Biographical Sketches of Committee Members and Staff
