Original Research by School Decision on Diboll
Diboll is a small adult charter high school operated by The Excel Center, a tuition-free program serving adults ages eighteen through fifty. The Diboll campus is housed inside a Texas Department of Criminal Justice correctional facility, making it one of five Justice Education Campuses the district operates within prison units across the state. This is not a traditional high school serving teenagers in a community setting. The school exists to offer incarcerated adults the chance to earn a high school diploma and participate in re-entry support services while serving their sentences.
The enrollment is small, with the majority of students in ninth and tenth grade, reflecting the varied educational backgrounds and entry points of adult learners. The student body is predominantly Hispanic, with a substantial share identifying as Black or white, and one student identifying as American Indian or Alaska Native. The racial composition reflects both the broader demographics of the incarcerated population in Texas and the region where the facility operates.
No state assessment data, graduation rates, or other standard school-performance metrics are available for this school. This absence reflects the nature of the school's population and mission rather than a data gap. Adult high school programs operated within correctional facilities sit outside the standard accountability frameworks applied to traditional K-12 schools and district schools serving the general population. The school is not subject to standard state testing requirements or the metrics used to measure traditional schools.
What the school does offer is a pathway to a high school diploma, not a GED. This distinction matters: students completing the program receive the same credential a traditional high schooler would, rather than an equivalency. The program also incorporates industry-recognized certifications alongside academics, preparing students for employment after release.
The Excel Center itself operates on a permanent, state-funded basis. The program was initially launched as a pilot but was converted to a permanent statewide program in 2021, secured through Foundation School Program funding. This permanence means the school is not a temporary initiative. For an incarcerated person considering education while inside, the assurance that the program will remain available, and that completing it yields a genuine diploma and career credentials, is substantial.
Austin, where The Excel Center's administrative structure is based, is a rapidly growing tech and education hub anchored by state government, the University of Texas, and major employers including Dell, Tesla, Samsung, and Apple. The city's economy is expanding quickly, and housing costs have been climbing, though the market has cooled somewhat recently. The broader metro region includes the correctional facilities where Diboll and the other Justice Education Campuses operate, extending the district's footprint across multiple towns. The Diboll unit itself is in East Texas.
For someone incarcerated seeking to earn a high school diploma and work toward re-entry, this school offers a rare formal education pathway. The lack of traditional performance data should not be read as a weakness; it simply reflects that this school serves a distinct population with distinct goals and operates under a different accountability structure. Parents, advocates, or family members supporting someone in this situation would want to speak directly with the campus about curriculum, certification options, and re-entry support services available.
