Internet access is instead provided through locally operated wireless networks, including InternetParaTodos, a community network developed by Kelvin Orduna. The network delivers connectivity to individual users and government institutions using wireless internet service provider (WISP) infrastructure. Public access is also available at Wi-Fi hotspots throughout the municipality via voucher-based (Spanish: ficha) systems that provide time-limited connectivity.

The municipality does not have institutions offering upper secondary or higher education. As a result, students must travel to nearby municipalities such as Santiago Tamazola, Silacayoápam, Huajuapan de León, or Oaxaca de Juárez to continue their studies. This requirement contributes to increased household costs which attribute to migration patterns among youth.

Municipal planning documents identify deficiencies in educational infrastructure, noting that many school facilities are in deteriorated conditions and do not meet adequate standards for effective educational use.
