Louisiana Educational Assessment Program for the 21st Century (LEAP 21) is an integral part of the Louisiana school and district accountability system passed by the state legislature and signed into law in 1997. In March 2004, students in grade 8 took LEAP 21 English Language Arts, Mathematics, Science, and Social Studies tests. This document presents student work in the Mathematics test, which was completed as part of a LEAP 21 assessment. The document includes examples of multiple--choice items and constructed--response items that exemplify what students scoring at specified achievement levels should know and be able to do. A discussion of each item highlights knowledge and skills it is intended to measure, as well as strengths and weaknesses in the student work on the item. The grade 8 LEAP 21 Mathematics test is composed of sixty multiple-choice and four constructed-response items. A student earns one point for each correct answer to a multiple-choice item and from 0 to 4 points for the answer and work shown for each constructed-response item. Scoring rubrics and general achievement level definitions are provided.
