Tuition Assistance Overview and Eligibility Information from GoArmyEd:
The Tuition Assistance (TA) program provides financial assistance for voluntary off-duty education programs in support of a Soldier's professional and personal self-development goals. TA is available for courses that are offered in the classroom or by distance learning. The courses must be offered by schools that are registered in GoArmyEd and are accredited by accrediting agencies that are recognized by the U.S. Department of Education. A list of approved accrediting agencies may be found at Go Army Ed: Accrediting Agenices In addition to degree programs, TA is available to Soldiers to complete a high school diploma and to complete certificate programs. However, TA will not be approved to complete credentials at the same or a lower educational level. TA is not authorized for programs beyond the master’s degree. All Regular Active and Reserve Soldiers, members of the Active Guard Reserve and Reserve Component Soldiers who are activated under U.S. Code Title 10 or Title 32 (officers, warrant officers, enlisted) will request TA through GoArmyEd (subject to qualifying criteria). National Guard Soldiers in drilling status do not access TA through GoArmyEd.
By law, officers who use TA incur a service obligation. Active Duty officers incur an Active Duty Service Obligation (ADSO) of two years and Reserve Officers incur a Reserve Duty Service Obligation (RDSO) of four years. The ADSO/RDSO is calculated from the date of completion of the last course for which TA was used. Non-Army servicemembers must obtain TA through their branch of Service. This policy has been mutually agreed upon by all Services. Further details on the provisions of TA are found in AR 621-5.
