Chief Constable Alex Marshall is retiring from policing and will take up a post tackling corruption in sport. Mr Marshall will join the International Cricket Council in September this year.
College of Policing Board Chair, Millie Banerjee, said: "Since beginning his policing career in 1980, Alex has dedicated himself to protecting the public, supporting his colleagues and developing the service.
"There have been significant changes to policing in recent years and Alex has been at the forefront of improvements designed to support officers and staff as they perform their difficult roles.
"Under his leadership, the College of Policing has established itself as the first professional body for the police and delivered important pieces of work such as a complete review of leadership across the service, plans for officers and staff to gain official recognition for their skills and experience and the first Code of Ethics.
"I would like to express my gratitude on behalf of College staff, Board members and colleagues across policing for his leadership and commitment.
"We wish him every success for the future and in his new role at the International Cricket Council."
Alex began his career as a police officer in 1980 at the Metropolitan Police Service. He was appointed Chief Constable of Hampshire in 2008 and joined the College of Policing when it was created in 2012. He holds a Masters Degree in Criminology from the University of Cambridge.
Chief Constable Alex Marshall said: "I am incredibly proud to have served for 37 years in the best police service in the world. I owe a huge debt of gratitude to the countless officers and staff I've worked alongside and who have guided and supported me during my police career.
"I'm looking forward to an exciting and challenging role with the International Cricket Council, when I join them in September.
"Until I leave policing to take up my new role, I will focus fully on continuing the important work of the College of Policing. In setting standards and being the professional body for everyone who works in policing, the College is there to support officers and staff in protecting the public and adapting to the rapidly changing nature of police work. The College Board and Professional Committee have provided me with huge support in delivering on these aims.
"There is a long tradition of policing in my family, which began with my great grandfather in 1902. I will always consider myself to be a member of the police family. I will watch with supportive interest as the College develops and continues to support those at the front end who serve and protect the public." A process to establish a successor will begin in due course.
