Veterans who are unable to attend full-time are encouraged to consider going part-time. Benefit rates for part-time training are less than the full-time rates. Likewise, the entitlement charge for part-time training is less than the charge for full-time training. For example, if a veteran receives full-time benefits for 12 months, the charge is 12 months. If a veteran received one-half time benefits for 12 months, the charge is six months.
