The original version, Version 1.0, of this document was first published in 2005. This current version, Version 2.0, includes updates based on feedback from faculty across the state. Also a listing of the Algebra I California Content Standards organized into clusters has been added in Appendix #1. Cal-PASS is unique in that it is the only data collection system that spans and links student performance and course-taking behavior throughout the education system-- K-12, community college, and university levels. Data are collected from multiple local and state sources and shared, within regions, with faculty, researchers, and educational administrators to use in identifying both barriers to successful transitions and strategies that are working for students. These data are then used regionally by discipline-specific faculty groups, called "Intersegmental Councils," to better align curriculum. This Algebra 1 deconstruction project was initiated by the faculty serving on the math intersegmental councils after reviewing data on student transition. This document represents a comprehensive review by K-16 faculty to deconstruct and align Algebra 1 (Elementary Algebra) standards. Appended are: (1) Algebra I California Content Standards by Clusters; (2) Developing Learning Targets for Algebra Standards (Deconstruction instructions); and (3) Categorization of Educational Outcomes (Explanation and instructions).
