A league system for Test cricket could be in place by 2019, according to International Cricket Council chief executive Dave Richardson.
The one-sided nature of England's current series against Sri Lanka led former captain Michael Vaughan to call for a promotion and relegation system.
"Hopefully we can make a decision by the end of the year over what structure to implement," said Richardson.
Currently, the only global competition for Test cricket is the ICC rankings.
The rankings are based on bilateral series arranged between individuals’ countries, with Test series varying in length and frequency, foreign media reports.
