This article presents the steps taken over three years (2003-2006) by the Consortium for Assessing Performance Standards, a New Jersey Grant Project to create a database of thematically organized, integrated performance assessment tasks at the benchmark levels of proficiency, novice-mid, intermediate-low and pre-advanced as defined by the ACTFL Performance Guidelines for K-12 Learners. The assessment tasks are available to world language teachers in the state of New Jersey and nationwide to measure achievement of the New Jersey Core Curriculum Content Standards for World Languages or the national Standards for Foreign Language Learning in the 21st Century. The library is available at www.flenj.org. Clicking on "Consortium for Assessing Performance Standards" at this web site provides access to 70 assessment tasks, rubrics and samples of student work for some of the tasks.
