Representatives of the 14 Super League clubs were this week given an update on the policy review being carried out by RFL chief executive Nigel Wood as part of the recommendations of last year's Watkins Report.
Among the items up for discussion were changes to the licensing system and a possible return of automatic promotion and relegation. Also under consideration is a reduction in the number of Super League teams from 14 to 12 or a new split league of 10 or 12 teams in each division.
No changes can be made before the end of the current licensing period, which runs to the end of 2014.
An RFL spokesman said: "Chief executive Nigel Wood continues to make progress on the RFL's policy review which will shape the future of the sport in the years ahead.
"The review includes a number of exciting ideas for the structure of the sport and the RFL is currently consulting with the Super League and Championships clubs and the community game on all aspects of the process ahead of publishing the proposals.
"The consultation process is expected to continue throughout the summer with any recommendations being voted upon later in the year."
The licensing system was introduced in 2009 to enable Super League clubs to plan for the long-term in the knowledge that their top-flight status is guaranteed for at least three years but there has been a groundswell of support for a return to promotion and relegation.
Wood said: "The consultation process so far has been very successful with positive contributions from everyone involved.
"What is apparent from our work to date is that all parts of rugby league want to see an integrated solution that ensures the vibrant future for the whole of the game."
