Since 2024, this option has been available in AV4 (https://av.santillana.es/). It can be carried out by the school's ICT coordinator or by submitting a request through the form, selecting the inquiry reason “Digital Technical Support,” the digital product “Aula Virtual 4 (AV4),” and the section where the issue occurs: “Bulk User Registration.” At any time, you can request more information about the process from the Santillana commercial delegate assigned to your school.
