According to the district's student handbook, such punishment is administered only if the student's parents had agreed to corporal punishment at the start of the school year, is reported on the student's record, and is limited to "three swats" per offense. In the survey year 2017, the US Department of Education reported that there were 18 total incidents of corporal punishment in Coolidge ISD and 10 out of school suspensions for the district's 308 students. This rate of incidence of corporal punishment is higher than the Texas state average, where in 2015-16 about 0.3% of students state-wide received corporal punishment.
