Gartner defines K-12 LMSs as those forming the core teaching and learning technology environment, with a range of internal and external tools and services that support classroom learning. LMSs are moving beyond a technology platform that only administers learning resources. They are designed to support functions such as developing and tracking assignments and assessments, and managing online interactions and collaborations among teachers, students, administrators and parents/guardians. Increasingly, LMSs offer advanced reporting and analytics capabilities, and are usually integrated with the SIS. In K-12, several vendors offer the SIS and LMS combined into one product.
