This series also, for the first time, doubled as a qualifier for the 2016 Summer Olympics, with the top four national teams qualifying automatically.

[1] The schedule for the 2014–15 Series was released to the public in early March 2014.

Fourteen of these teams qualified via their placement in the 2013–14 series.

In addition to the previous season's top 14, Japan joined the core teams as they were the winners of the qualifying tournament during the 2014 Hong Kong Sevens.

Spain, being the last placed core team for 2013–14, were relegated and lost their status as a core team for the 2014–15 season.
