Speculation earlier today claimed that the Toffees had beaten off reported competition from the likes of Tottenham Hotspur and Newcastle United for the 23-year-old.
The Merseyside have now confirmed those rumours via a short statement on their official website.
"Everton has agreed a deal with FC Twente for the transfer of Dutch international Leroy Fer," it read. "The 23-year-old midfielder will now head to Merseyside to discuss personal terms and undergo a medical."
Fer, who has made two appearances for the Dutch senior national side, is thought to be costing Everton around £8m.
