The consequences of not graduating from high school are increasingly serious for both individuals and society as a whole. As a result, state and federal accountability systems now require reporting of more detailed graduation and dropout data. The federal No Child Left Behind Act of 2001 (NCLB) requires states to report disaggregated "on-time" graduation data for nine groups of students: the five major racial/ethnic groups, students with disabilities, students with limited English proficiency, students from economically disadvantaged families, and all students combined. Under certain conditions, the rate for these groups helps determine if a high school makes "Adequate Yearly Progress" (AYP) for federal accountability purposes. This report provides three types of results at the state, county, district, and school levels: (1) annual dropout rates for the 2003-04 school year; (2) estimated graduation, dropout, and continuing rates for the cohort of students who were expected to graduate in 2004; and (3) extended graduation rates that include students who finish after their expected year of graduation. Since the percentage of students in each category can be calculated in different ways, making comparisons across schools, districts, and states and from one year to another should be done with caution. Appended are: (1) Annual Dropout Statistics for Districts and Schools; (2) Cohort Graduation Statistics for Districts and Schools; (3) Extended Graduation Statistics for Districts and Schools; and (4) County Dropout and Graduation Statistics.
