The International Sepaktakraw Federation, commonly known as ISTAF, is the international governing body for the sport of Sepak takraw, which was formed in 1988 with five founding member countries including Malaysia, Thailand, Singapore, Indonesia and Myanmar, officially based in Thailand and with its secretariat in Singapore.

[1] Its main goal currently is to spread Sepak takraw into 75 different countries and ultimately make it an Olympic sport by 2026.

[13] It is played similarly to volleyball but players use their feet, knee, chest and head to carry a rattan ball over the net.

[31] All international regu tournaments approved by the ISTAF might apply to the federation to estimate the world ranking points.

The competition is held in a grand prix format whereby national teams compete in a series of events during a season.

[37] The finals of ISS 2011/2012 see Thailand being crowned the overall champion for both men and women in front of their home crowd in Bangkok.
