The UNED has an Internal Quality Assurance System (SGIC-U) that covers all its official undergraduate, master's and doctoral degrees, as well as the services it offers, whose design was certified by ANECA.

The SGIC-U includes all the processes necessary to ensure the quality of its faculty, resources and services for students: access, admission and reception, external internships, mobility programs, academic guidance and job placement, monitoring and evaluation of the results of training, attention to suggestions and complaints and the adequacy of support staff, among others.

Those responsible for the IQAS are:

The Coordinating Committee of the Degree.
The Quality Assurance Committee of the Center.
The Dean's or Management Team.
The Quality Assurance Commission of the UNED.
Through the Statistical Portal, the UNED provides information to the entire university community on both the results of training and the results of satisfaction of the various groups involved.
