Schools are trying to recruit former soldiers to the classroom to fill gaps left by teacher shortages and declining applications to join the profession.
Others are sponsoring sports teams to try to attract new teachers, or encouraging former pupils to join.
The government is on course to recruit fewer than half of the secondary trainees required for the next academic year, according to forecasts by the National Foundation for Educational Research.
Schools are looking beyond careers fairs to bolster applications, with some using TikTok, Instagram and LinkedIn to appeal to graduates. Others are contacting the armed forces in the hope they might recommend teaching to soldiers who are retiring, the Schools Week website reported.
