Gerry Carr has left his role as Chesterfield's academy manager by mutual agreement.
Carr, who worked with former Spireites manager Paul Cook at Sligo Rovers in Ireland, joined Chesterfield in the summer of 2013.
Spireites chief executive Chris Turner said: "I would like to thank Gerry for his efforts over the last two years and wish him all the best for the future."
Carr said: "I have thoroughly enjoyed my two years as Chesterfield’s academy manager and feel the club will see the benefits of the work I have done in the forthcoming seasons. I feel it is now the right time to pursue other opportunities in the game and I wish Chesterfield good luck for the future.”
An announcement regarding Carr's successor will be made in due course.
