Joint Knowledge Online Learning Management System (JKO LMS) is a virtual environment that provides a learning management system (LMS) integrating web–enabled content to support online certification and career management. It is a SCORM–conformant government–off–the–shelf (GOTS) web–based LMS. An LMS is a software tool designed to manage user learning interactions. A web–based LMS provides “anytime, anywhere” access to e–learning content and administration.

JKO provides 24/7 global access to online training courses and Web-based training resources. The capability delivers Web-based access on military classified and unclassified networks to required, theater-entry, and self-paced training to prepare for joint operations and training exercises. It is used by combatant commands, Combat Support Agencies, Services and other DoD organizations for individual online training requirements, distributed small team staff training and to augment collective events and exercises. JKO is based upon a modern, scalable architecture that can readily adapt to meet emerging needs. The distributed learning architecture integrates government off-the-shelf products and commercial interface standards, reducing total overall costs and enhancing sharing of digital training content through a standards-based, non-proprietary distributed learning capability. Learning resources include media- rich courses, tailored, immersive scenario simulation applications for small group exercises, area-specific language and culture training, Senior Enlisted Joint Professional Military Education courses, and a video library. JKO is accessed on military classified and unclassified networks and mobile devices. Information on JKO is found at or is available by going to http://jko.jten.smil.mil
