Bath head coach Mike Ford and his backroom staff have signed new deals with the Premiership club.
Ford, Toby Booth and Neal Hatley, who led the side to a fifth-place finish in the league and the Challenge Cup final last season, are now under contract until the end of the 2015-16 campaign.
Bath have also announced former Newport Gwent Dragons boss Darren Edwards has joined as first-team coach.
The 40-year-old's five-year spell with the Dragons came to an end in February.
Former Wales scrum-half Edwards said of his appointment at Bath: "They have a fantastic and dynamic young squad, who have masses of potential to build on.
"It's a really exciting time to be joining the club and I'm looking forward to helping them reach the ambitions they have over the coming seasons."
Ex-London Irish boss Booth, former Exiles prop Hatley and ex-England defence coach Ford arrived at the Rec in May 2012 to work under director of rugby Gary Gold.
Bath finished seventh in the Premiership in their first year at the club and were sitting third in the table in December when Gold was dismissed from his role. with Ford taking over at the helm.
His side looked set to reach the play-offs this year, but a final-day defeat by Harlequins saw them miss out on a top-four finish.
"We made huge progress as a squad last season, but only really scratched the surface of what this group of players can do," said 48-year-old Ford.
"We want to build a team culture on and off the field that will create success, and we have definitely made great inroads into that.
"I know I speak on behalf of all four of us when I say we are dedicated to the club and can't wait for the new season to start so we can pick up on the momentum gained and carry on our improvement as a squad."
