On 13 November 2010 the International Hockey Federation (FIH) decided to allocate 12 teams for each men and women events respectively.

Each of the continental champions received a berth alongside the host, Great Britain (England, Scotland and Wales compete separately in most competitions, but send a combined team to the Olympics and selected friendly tournaments, which is managed by England Hockey),[2][3] while another three spots were decided in qualifying tournaments.

While for the women's, Asia, Oceania and Europe each received one extra quota place.

Instead they played in the men's and women's Olympic qualification tournament and made the cut.
