It  was part of the European Union (EU) backed Training and Education Portal (TEP) project.

Sixteen coaches from England, Ireland, Germany and the host nation took part.

Leon Crick and Chev Walker, foundation coaches with English Super League side Leeds Rhinos, also attended as project partners.

"The course was very helpful for me as a coach and as a player," said German coach Mawuli Amefia.

"I've learned a lot and I can't wait to pass the knowledge on in Germany. 

"The course once again helped me understand how important coaching the basic core skills is to players, no matter what level we are at."

All attendees will now undertake a series of continuing professional development tasks, which will be used to evaluate their competence and progression.

"It was a very good, productive four days working with coaches from different countries," said Ireland's Mike Aughey.

"There were very open discussions and input from all, and great practical and classroom sessions led by our partners Leeds Rhinos."

The TEP is a three-year, €723,000 (£639,000/$867,000) investment into capacity building through good governance and technical training.

It is funded by €466,000 (£412,000/$559,000) from the EU's Erasmus+ project and the remainder from the RLEF and five of its full members. 

It is intended to build the knowledge and skills of the 21 European members, divided into six regional clusters.

This will be done through high quality training and mentoring, while granting opportunities to share experiences among fellow-Europeans dedicated to rugby league development.
