The OneRoster™ standard is a subset of the Learning Information Services standard that focuses on the school's needs to exchange roster information and grades.  For Duncanville ISD, OneRoster™ ability is the key to streamlining student roster information between software systems.  This ability allows for quicker student and staff access to instructional tools.

Common Cartridge and Thin Cartridge is a standardized way to package and exchange digital learning materials and assessments.  This standard allows DISD a way to exchange links and provide authorization to third-party web-based learning tools via Learning Tools Interoperability.  It also empowers Duncanville ISD to import and export course materials to and from Learning Management Systems, Portals, Learning Object Repositories or other Learning Platforms. 

Learning Tools Interoperability® (LTI®) is a specification developed by IMS Global Learning Consortium.  The principal concept of LTI® is to establish a standard way of integrating rich learning applications, which are often remotely hosted and provided through third-party services, with platforms like Learning Management Systems, Portals, Learning Object Repositories and other educational environments.  LTI® empowers Duncanville ISD to cross-integrate educational content between vendor products.
