Since 2012, the U.S. Department of Education, U.S. Department of Justice and the Supportive School Discipline Initiative (SSDI) collaborated in helping schools move toward a more restorative way of engaging students, and using suspensions and expulsions only as a last resort. The purpose of this quantitative study was to determine if there is a significant difference in the number of referrals and the attendance rates between secondary schools in South Texas which use Restorative Practice (RP) and those which do not. This study collected data over three school years to determine the type of impact restorative practices has on discipline referrals and student attendance rates. The comparative study used data from four secondary campuses located in two school districts with similar student demographics in South Texas. Restorative practices were found to be impactful in public middle schools by statistically and significantly reducing the number of discipline referrals, while in public high schools, (RP) supports to increase student attendance rates. Results may help school leaders make the best decision for discipline practice in order to positively affect student achievement.
