The Utah, Colorado, Arizona, New Mexico-Rural Systemic Initiative (UCAN-RSI) supports systemic improvement in science, technology, and mathematics education for all rural students in the four states, focusing on schools that enroll large numbers of American Indian and Hispanic students. This document contains a report on UCAN's 4th year (September 1998-August 1999) and its strategic plan for year 5. UCAN's 4th-year efforts aimed to accelerate implementation of standards-based curricula in focal schools. New partnerships and additional funding increased support for teacher professional development, educational capacity building, and community engagement. At the beginning of the program year, UCAN's Navajo Nation Coalition was funded as a separate RSI, and its data are excluded from this report. Part 1 of the annual report presents data on science and mathematics achievement for New Mexico and Arizona students in UCAN-targeted schools, UCAN-eligible but nontargeted schools, and other schools. Part 2 provides data on teacher professional development and number of students impacted. Part 3 describes activities related to UCAN's six overarching goals: leadership training for systemic reform; school data use as an educational planning tool; school-community networks; modeling and mentoring among UCAN schools; multistate, multijurisdictional cooperation; and community outreach focused on standards-based education. Part 4 highlights activities and outcomes for specific schools and coalitions. The 5th-year strategic plan focuses on further strengthening reform structures of school and community networks and discusses each of UCAN's six main goals in terms of the UCAN legacy and sample coalition plans.
