The King gave permission in 1904 to name the School after him following a petition by Sheffield City Council.

King Edward VII School was founded in 1905 by Sheffield City Council. The councillors wanted to establish a high performing school that would give a very good education to all its pupils and also send many of them to Sheffield, Oxford and Cambridge Universities.

The School moved into Broomhill after a year of alterations to classrooms and the creation of a new assembly hall. Previously, the building was on Collegiate Crescent, which is now part of Hallam University's Collegiate campus

The Junior School moves to a large house on Newbould Lane opposite the School gates, previously the School was based on the lower corridor of Upper School. There were 331 pupils, all boys aged from 8-19 years.

School numbers had grown to 600. People in Sheffield often referred to the school as 'King Ted’s', but it preferred to call itself KES. Almost everyone had to pay fees (just over £19 a year).

A quarter of pupils got a free education because they had passed their scholarship at 11 years of age, but the School was still only for boys. About 30 boys were boarders and they lived in a large house nearby on Clarkehouse Road that was owned by one of the teachers. Today it is a pub that is called the Francis Newton.

KES had gained a reputation in the whole of Yorkshire, but many of the former pupils would very sadly be killed in the war while serving as junior infantry officers on the battlefields of the Somme, Arras and in the Ypres Salient. Old Edwardians were awarded thirty-two medals for gallantry during the War. During the War the school included some boys who were refugees from Belgium and because many teachers were in the Army, there were women teachers at KES for the first time. After the War the school built a War Memorial to remember the 90 former pupils and two teachers who were killed in the War. It is in the form of a stone cross and still stands just near the south-east corner of the main school building.

The School was admitted to the Headmaster’s Conference and therefore could define itself as a Public School.

School had its only Army OTC cadets (the Officers Training Corps) with 100 pupils in its ranks. It was opposed by the newly elected Labour Council in 1926 who did not want to see young boys preparing for war

KES OTC was abolished in 1927. This decision of the Council caused a national furore and the Headmaster resigned and the school lost its public school status. Instead the school formed a large troop of Scouts that continued until 1974.

Built in the corner of the School grounds it replaced an old open-air pool that had been built by Wesley College. Also at this time, the Junior School moved into Clarke House. It is now the Junior School of Birkdale School

Start of term was delayed in September until air raid shelters were built. They are still there today and full intact

Boys ran messages, looked out for fires and helped rescue people. One boy was presented to the King because he had been especially courageous during the Big Blitz in December. Sadly, 110 Old Edwardians died with many of them flying with the RAF

KES became a Grammar School, meaning boys had to pass a scholarship exam at the age of 11 to join the School, qualifying them for a free education

KES became a Comprehensive School and admitted girls for the first time. Numbers increased to 1,270 students and Lower School was established on Darwin Lane. Sixth form moved to Newbould Lane, now part of Girls High School

KES and five other Schools in south-west Sheffield were allowed by the Government to keep their sixth forms, despite the Council proposing that all Schools educate their pupils from 11-16 years of age only

A new Lower School was built and the old building was demolished (it stood where the all-weather pitch is now situated)

Upper School was totally refurbished and a new sports hall and science labs were added

Mrs Jackson, the first woman to be head, was appointed. She later retired in 2016 after the School had been rated outstanding by Ofsted

Ms Gooden became the ninth Headteacher of KES and still holds the position today
