HB 2591 modifies the operation of juvenile justice alternative education programs (JJAEPs) in Texas. The bill removes the requirement for counties with populations over 125,000 to operate a JJAEP, instead making participation optional for all counties. It also updates compulsory school attendance exemptions to specify that students expelled in a district without a JJAEP are not required to attend school. Additionally, the bill clarifies that students expelled in a county operating a JJAEP must immediately enroll in the program as part of their release conditions from juvenile detention​.
