The flagship Troops to Teachers scheme retrains ex-servicemen and women as teachers and has seen 28 veterans qualify since it commenced.
Former education secretary Michael Gove had hoped to attract 2,000 applicants to the £4.3 million scheme. The government said that the scheme's impact is so far positive and is set to grow.
This number is the first round of trainees to graduate from the scheme. Schools minister Nick Gibb said that a total of 551 applications has been received for the scheme, which began training people in 2014.
This saw 41 individuals start the programme in its first year, with 28 of the 29 who completed it achieving qualified teacher status.
Shadow education secretary Lucy Powell said: "I very much want to see more veterans re-training to become teachers as they have a huge amount to offer and we desperately need more good teachers."
A Department for Education spokesman said: "The 28 graduates referred to are the first trainees to be recruited and completed their two-year course at the end of December."
Two further cohorts are currently in training, which puts more than 140 former troops currently working in British classrooms.
The spokesman added: "The impact of these recruits in the classroom has been overwhelmingly positive with head teachers praising the influence they've had on pupils' attainment."
The Troops to Teachers scheme, run by the University of Brighton, is based on the idea that military values such as leadership, discipline, motivation and teamwork are particularly useful for teaching, an idea that has been proven by the scheme's success to date.
