This document contains a brief overview and introduction to the Urban District Assessment Consortium (UDAC), sample performance items with student responses, and sample open-ended items with student responses. The UDAC is a multiyear cooperative effort that is comprised of 11 major urban school districts across the United States and the Center for the Study of Testing, Evaluation, and Educational Policy at Boston College (Massachusetts). The goal of the UDAC is to develop and disseminate authentic-assessment instruments as alternatives to the traditional standardized tests for school-accountability purposes. The UDAC is based on the belief that the relation between classroom instruction and accountability assessment should be an integrative one. The UDAC's instruments, which include open-ended and performance-based tests in reading, writing, mathematics, and science for grades 4 and 8, have been developed to reflect emerging national standards in each of these areas. The UDAC assessments are racially, ethnically, and linguistically inclusive, and are offered in English and Spanish to accommodate the language needs of the greatest number of urban students. Appendix 1 contains sample performance-based test items and student responses, and Appendix 2 contains sample open-ended test items and student responses. (Contains 3 references.) (SLD)
