This report summarizes Intercultural Development Research Association analyses of attrition rates for high school students enrolled in Texas public high schools. Enrollment figures were examined for students who were in the 9th grade during the 1988-89 school year and students who were in the 12th grade during 1991-92, and results were compared to those of previous annual studies. Findings indicate that: (1) the rate of attrition (33 percent) has remained virtually constant over a 7-year period from 1985-86 to 1991-92, with Hispanics having the highest percentage of dropouts; (2) the annual number of students lost from public high school enrollment through attrition has remained virtually constant over the 7-year period; and (3) attrition rates were higher for ethnic minority students than for White non-Hispanic students and for males compared to females. These findings are consistent with the trends reported by the Texas Education Agency. Additional research should examine the effectiveness of dropout prevention initiatives, particularly as they relate to minority groups and males. In addition, school districts need to establish better record keeping with regard to reasons why students drop out of school and their status after they fail to attend school. A school district network should be established to keep track of student attrition. Attrition rates are listed by county and race. (LP)
