Mr Doe, aged 53, has been at the paper since 1973, first as a reporter and then as features editor before becoming deputy editor in 1989 and managing editor in 1997. He has been acting editor since November when Caroline St John-Brooks resigned on health grounds.
A father of three children, who all attended state schools, Mr Doe spent 20 years as a school governor in Brighton.
He said: "I have developed an enormous respect for the readers of The TES over the years. So it is a great privilege to be asked now to edit the paper and continue th development of it begun so well by Caroline St John-Brooks.
"We know our readers work under considerable pressure. So our new-look news section launched last week is designed to make the paper easier to read and to give them more practical and moral support.
"We cannot report only good news. We have always tried to report on education fairly. But now I hope we can also give more attention to the ways good teachers and those who support them are responding successfully to the challenges in schools and colleges. The TES must both celebrate and share the secrets of that success with its readers."
