Universities are making great efforts to provide quality and inclusive education for all. However, the number of students with disabilities or educational needs studying higher education is still low. Student support resources are essential to the success of inclusive education. An inclusive education indicator has been developed that establishes a ranking of those universities best prepared to offer inclusive resources. As an example, the indicator has been developed for the case of Spanish public universities, based on information provided by the Spanish Network of Support Services for People with Disabilities at University, which produced an online University Guide for Students with Disabilities with several areas and points that collect information on the resources available at universities. This indicator is dynamic and can be updated quickly and easily. Through it, universities may know in which aspects they need to improve. In addition, they could take as a reference those universities that are better positioned according to the value of the indicator.
