The International Hockey Federation (FIH) has also restructured its officials set-up as part of the scheme, which the organisation claims will "significantly increase" the quality of refereeing across the sport.

The programme includes increased fitness standards, educational and psychological training, match preparation and a talent identification scheme.

Technical officials and umpire managers at men's and women's international events governed by the FIH will also now have equal representation of gender.

Under the new system, referees will be categorised based on their standard of officiating.

The updated structure includes a top-level Olympic Games panel, ranging down to a talent development panel.

The top group will be made up of referees who will officiate at the Games, while seperate panels have been established for World Cups and the newly-launched Hockey Pro League.

"This is an important step towards increasing the degree of professionalism within hockey," FIH director of sport and development Jon Wyatt said.

"We believe that we have some of the best officials in world sport, but as our game continues to develop apace we need to ensure our officials remain ahead of the game.

"We are convinced this new structure will not only raise officials’ performances but more importantly ensure they reach their full potential across all levels of international hockey. 

"Such development will undoubtedly result in a better on-field product which will subsequently enhance our already amazing game."
