The Defense Threat Reduction Agency (DTRA) is seeking potential sources to develop a new Student Information System (SIS) for the Defense Nuclear Weapons School (DNWS) to replace its outdated Learning Content Management System. The new SIS is required to efficiently manage core functions such as course registration, student data, and transcript access, while ensuring integration with existing Learning Management Systems and robust cybersecurity measures. This initiative is crucial for enhancing educational operations and supporting the unique training and record-keeping needs of military personnel. Interested companies should submit their responses, including company information and capabilities, to Erika Hebert at erika.l.hebert2.civ@mail.mil, with the subject line “Sources Sought # HDTRA125R0061.” Responses are due by the specified deadline, and no funds are available for preparation costs.
