Medlycott would be responsible for physical and mental conditioning, skill development and match day activities of the umpires. ICC boss Malcolm Speed said the post wouldl go a long way in "attaining ever higher levels of correct decision-making".
Speed further said that the role Keith will play would immensely help in the coaching and development of the top officials. "Keith will assume charge of an important post that would help in the coaching and development of the game's top officials."
A former spinner, who never played a Test match, Medlycott stepped down as Surrey coach at the end of last season. He will take up the post on October 1.
Looking ahead to his new job, Medlycott said he was excited to work with the top-flight international umpires: "I'm excited and looking forward to working with the Emirates Elite Panel of ICC Umpires. I am confident I would be able to apply the people-management skills I have evolved as a player and coach over the last 20 years in this new environment,"he added.
