Every Territorial Army (TA) Officer in the British Army commissions from the Royal Military Academy Sandhurst.  However, there are two different routes to the Academy.  One is through the University Officer Training Corps (UOTC) for university students; the other is through a local TA unit.  Both involve the completion of three qualifying modules before applying for the TA Commissioning Course (TACC) at Sandhurst.  There are two TACCs per year: one in July, the other in September.  

In order to be accepted onto the TACC, applicants first have to pass an Army Officer Selection Board (AOSB) at Westbury, which is identical in all respects to the Regular AOSB.  The Sandhurst course is three weeks long and consists of an intensive revision period in week one, followed by a two-week test period that includes a seven-day tactical exercise in the field.  The course ends with an impressive, formal Commissioning Parade in front of Old College to which family and friends are invited.  

Someone who holds a TA commission will have learned a wide range of valuable leadership and managerial skills that can also be used in the civilian workplace.  For that reason, many employers actively support employees who wish to become Territorial Army Officers.
