A systematic implementation of Direct Instruction, involving training and support, began in 24 schools in the fall of 2003, starting with the lower grades and gradually expanding to the upper grades. In the fall of 2008 15 of these schools ceased using DI, while the remaining schools and two additional newly created schools, continued to use the program.enCreative Commons BY-NC-ND 4.0-USTechnical ReportAcademic AchievmentFirst GradeFifth GradeTechnical Report
