David Unsworth will leave his position as the Club’s Academy Director and Under-23s manager.
Unsworth said: “This has been one of the hardest decisions I have had to make in my career.
“Everyone knows what Everton means to me, it has been my whole life and I have loved every minute of my time here.
“However, to give me the best chance of achieving my career aspirations – and becoming a permanent first team manager – I believe now is the right time for me to move on.
“I would like to thank everyone I have worked with over the last nine years and the Owner and Chairman for the opportunities they have given me and for their unstinting support.
“Everton is an amazing club and a club I will love forever – I wish everyone connected with Everton, every success in the future.”
