The Response to Instruction and Intervention (RtII) program for junior high students at United High School is an educational effort to provide instructional interventions to promote student achievement. Interventions are part of the general education curriculum. RtII is not a special education program.

All students in grades seven and eight are given screening assessments in the fall and again later in the school year to determine current performance levels, identify learning needs, and to find those who are at risk for academic difficulties. Based on these screening results and other academic data, students may then receive additional academic instruction in reading, math, and science or support from a teacher through the mentoring program. This supplemental instruction and support occur during the dedicated Supplemental Instruction (SI) period.
