Part of a national research project, this study of students at risk involved elementary and high school pupils in the El Paso (Texas) area. Investigators sought answers to questions concerning the identity and characteristics of at-risk students, and school intervention programs and their effectiveness. Data were gathered on 296 students in three schools. Information collected included presence or absence of 45 at-risk factors and the frequency of use of 13 strategies designed to help students succeed. A "holding power statistic" was computed for the high school; an intensive case study was done on one student; and records of 40 pregnant girls were examined. Findings indicated that 40 percent of the students were seriously at risk, in contrast with 25 percent in the national sample. Males were found to be slightly more at risk than females. Hispanics were most at risk, followed by Blacks, Native Americans, Whites, and Asians. Principals and teachers reported spending 21 percent to 30 percent of their time with students at risk and 80 percent felt their efforts were average or above average in productivity. Strategies most frequently used to help students included parent involvement, computer instruction, tutoring, extra instruction in basic skills, and flexible scheduling. Strategies considered most effective included extra instruction in basic skills, placement in classes smaller than typical, parent involvement, use of special teachers, and special education. Discussion concludes with recommendations.
