In the summer of 2006, as part of the Army's "Centers of Excellence" Concept, Fort Jackson established the Directorate of Basic Combat Training (DBCT) to operate as the think tank and operational staff action clearing house for Basic Combat Training (BCT) issues as Fort Jackson itself transitioned from being an Army Training Center (ATC) to the BCT Center of Excellence (BCTCoE).
To accomplish this concept, the DBCT was formed by consolidating existing entities throughout the United States Army Accessions Command (USAAC). Specifically, Victory University (VU), the Drill Sergeant Program Proponent Office (DSPP), the Research Analysis Cell (RAC), and the United States Army Physical Fitness School (USAPFS) were combined under a single headquarters and organized as operating divisions within the DBCT. In addition, responsibility for the management of the BCT program of instruction was transferred from the Infantry School at Fort Benning, GA, to the new DBCT. The USAPFS physically relocated to Fort Jackson, SC, the following year. The RAC was re-designated as the Experimentation and Analysis Element (EAE) while the DSPP was re-designated as the Doctrine and Training Development Division to reflect their increased mission scope under DBCT.
During the summer of 2008, following USAAC's assignment as a direct reporting unit to the Secretary of the Army, TRADOC began work to separate the Accessions and Initial Military Training (IMT) responsibilities and split them into separate component commands under TRADOC. The concept called for the creation of a DCG-IMT (Replacing the USAAC Commander's alternate position designation as the DCG-IET) who would take over responsibility for all aspects of initial training for all military cohorts, thus expanding the previous mission scope which only affected enlisted Soldiers.
As part of this transition, the DBCT was reassigned from being a BCTCoE asset (which concurrently was redesignated back to being an ATC) to the newly established Deputy Commanding General-Initial Military Training (DCG-IMT) with the name Training Strategy and Support Directorate. This name was iterated several times as the organization functions were nested (changing to Training Strategy and Schools Directorate and finally to its final name under this model, the Training Support and Schools Directorate). The TSSD was officially task organized under a Depatment of the Army Stationing Authorization as Initial Operational Capability (IOC) on 1 October 2010 with a Full Operational Capability (FOC) requirement of 1 October 2011.
Under this reorganization, the EAE was redesignated as the Human Dimensions Section and reassigned to Fort Eustis, VA, to operate under the newly created Analysis Directorate reporting to the DCG-IMT Chief of Staff. Victory University was redesignated as Leadership Development and Training and Training Support (LDTTS) before being redesignated again to FOC as the Leadership Development Division (LDD). The USAPFS was redesignated as the Physical Readiness Division (PRD). In addition, the United States Army Drill Sergeant School (USADSS) was transferred from Fort Jackson, SC, to DCG-IMT, subordinated under TSSD for support purposes, but operationally controlled by the DCG-IMT Command Sergeant Major.
In the spring of 2012, TSSD executed a functional role assignment change between its divisions. Previously, each division with proponent functions had operated semi-independently. Specifically, PRD and LDD had internal assets for development of the courses and instruction material under their proponent responsibility. Under the functional assignment, the divisions maintained control of their executive agent proponent responsibilities but training development responsibilities were consolidated under the DTDD while Quality Assurance (QA) assets were consolidated in to Headquarters, TSSD.
In May 2013, as part of the University Concept under development by TRADOC, TSSD was directed to reorganize as Victory College effective 1 October 2013. Under this reorganization, multiple name changes occurred.
