The TEXAS STaR Chart measures school technology progress across 4 key areas: Teaching & Learning, Educator Preparation, Administration & Support, and Infrastructure. Each area is rated on a scale from Early Technology to Target Technology based on metrics like student to computer ratios, technology integration, and staffing levels. The document provides examples of the criteria for ratings at each level of progress within each category. It then summarizes one school's ratings across the 4 categories for 2006-2007 through 2008-2009, showing improving levels of technology adoption over time.
