The origins of NAMS dates back to the 1994 season, when the innaugural competition was won by the University of Birmingham Medical School RFC. Since then, the competition has grown and remained an integral part of the calendar for many Medical Schools throughout England and Wales, with fixtures against other Medical Schools being the highlights of their calendars. Since then, the competition has been dominated by Cardiff Medicals RFC, who have won the competition more than any other side by quite some margin, with Southampton University Hospitals RFC winning twice in a row in the 2011/12 and 2012/13 seasons. The 2014/15 season saw Sheffield Medicals RFC win the competition for the first time, and in doing so became the first time outside of the South-West and Midlands Divisions to win the competition.
Traditionally, the teams were split geographically into 4 divisions; the South-East, South-West, Midlands and Northern Divisions. Originally the sides would play each other twice, with the top two sides from each division progressing through to the Cup Knockout competition, and the remaining two sides progressing through to the plate competition. However, in recent years, due to the decline in numbers of some Medical Schools sides, and some Medical School sides beginning to compete in local Men's league, it was decided that each side would only play each other once (with the addition of the Bonus Points rule introduced). At the same time, the South-East division collapsed due to the London Medical Schools external commitments.
However, with the re-introduction of GKT in the 2014/15 season and the introduction of the Medical Schools Rugby League being introduced alongside the NAMS Competition, there are signals that the standard and depth of Medical Schools Rugby is stronger than ever.
