When schools fail to address the problems of struggling students, the consequences can be dire: course failures, absenteeism, suspensions or expulsions, dropouts. Those effects continue to ripple after school with lower rates of college attendance and graduation, underemployment and lower wages, and even incarceration.

Whether it's a student with ADHD who has trouble sitting still, a student just arrived from the Dominican Republic who speaks no English, or a traumatized student who dissociates in class, there are strategies that have proven effective in overcoming the hurdles they face. This guide will help teachers recognize the most common barriers to learning and apply solutions that will work in their classrooms.
