Standards-based infrastructure for tracking learning activities, managing competencies, and maintaining learner records across defense, workforce development, and education systems.
The Total Learning Architecture (TLA) originated from the U.S. Department of Defense Advanced Distributed Learning (ADL) Initiative and has transitioned to IEEE LTSC for formal standardization. TLA encompasses multiple interconnected standards enabling organizations to build interoperable, adaptive learning systems.
