The National Education Data Model is a conceptual but detailed representation of the education information domain. The Education Data Model strives to be a shared understanding among all education stakeholders as to what information needs to be collected and managed at the local level in order to enable effective instruction of students and superior leadership of schools.

The Education Data Model can be used by educators, vendors, and researchers to understand the information required for teaching, learning, and administrative systems. The Education Data Model answers questions such as:

What data do schools need to collect and manage in order to meet the educational needs of their students?
What information is needed to effectively manage education organizations such that teaching and learning is successful?

Estas son las variables que busca precisar la base de datos:
