Per Air Force Policy letter 2002-09, dated July 2002, the Air Force replaced the former Bootstrap program with the Air Force Educational Leave of Absence. The Bootstrap program was replaced because there were several details of this older program that were illegal under the US Code (Title 10, Sec 708). The new program, abbreviated as both AFELA and just ELA, allows for Air Force members to attend an accredited school full-time to obtain a degree of any level (including PhD). The next revision of Air Force Instruction AFI 36-2306, Air Force Education Programs, promises to outline this program in detail.
To qualify for the ELA, members can be either officer or enlisted. For enlisted members, they must have completed their initial enlistment and have reenlisted. For officers, they must have completed their initial period of obligated service incurred from their commissioning source. In each case, the member must also be retainable and agree to a 2 for 1 service commitmentfor every 1 day of time on ELA, the commitment is 2 days, with this ELA commitment starting upon completion of the program. To be on ELA, the member must be enrolled full-time as defined by the educational institution. Finally, the member does not need to have completed coursework in this degree program prior to starting ELA.
ELA is authorized for up to 2 calendar years, including term breaks. Because this program is new, your local education office may suggest ELA is authorized for just 1 year, since the old Bootstrap program was only authorized for this length. However, ELA is indeed authorized for up to 2 years, per the policy letter and the US Code (Title 10, Sec 708). Your education office may require justification or a waiver to be signed in order to go beyond one year.
While on ELA, members continue to be active duty, retain all medical benefits, build time in rank, can be promoted, etc. However, members will receive their base pay only. No allowances are authorized. This means no BAH (Basic Allowance for Housing) or BAS (Basic Allowance for Subsistence). If living on base, the member will be charged rent during the time they are on ELA. However, certain incentive pays, including retention bonuses, are usually still allowed. (In general, if it is pay, and is therefore taxed, you still receive this while on ELA. Allowances, which are not taxed, are not authorized during ELA.)
Furthermore, the Air Force does not pay for any expenses incurred for attending school. So Tuition Assistance (TA) and moving expenses (if moving from your assigned base to attend school) are not authorized. It is therefore important for ELA candidates to consider whether TA or the opportunity to attend school full-time is more important for their situation.
Finally, while on ELA, members continue to accrue leave, at the usual rate of 2.5 days per month. Members are not charged leave for term breaks. This is because the member is already being charged a 2x service commitment, and it would be illegal to charge a service commitment for time that is also being charged as leave.
