St Ambrose College is an 11–18 Christian Brothers' Roman Catholic boys' grammar school in Hale Barns, Altrincham, Greater Manchester, England.

Arriving in Hale in 1940 from Les Vauxbelets College in Guernsey, the Brothers, and a small group of students soon found suitable accommodation and re-established their school.

Towards the end of June 1940, when the Channel Islands were about to be occupied by the German army, the parents of boys attending Les Vauxbelets College, were asked to decide whether they should allow their sons to be evacuated to Great Britain or keep them at home with all the attendant risks (hunger, forced labour, etc.).

The college was in the charge of the French Province of the Brothers of De La Salle and they had promised that an appropriate number of the community would accompany the evacuees to care for them and to ensure that, as far as possible, their education did not suffer.

During the war the college began to grow in popularity, especially as there was no Catholic school for boys in the South Manchester area.

In April 2004, after the school's second bid for specialist status in six months failed, the headmaster Michael Thompson accused the Department of Education of bias.

The Sixth Form has been given a more visible role, giving presentations and talks during assemblies and during a Thursday morning tutor period.

[6] St Ambrose College, which was considered the school in Trafford "most in need of a new building",[7] was awarded £17 million in July 2006 to completely rebuild.

[7] In 2010,[needs update] the Trafford Local Education Authority was ranked seventh out of 150 in the country – and first out of Greater Manchester's 10 LEAs – based on the percentage of pupils attaining at least 5 A*–C grades at General Certificate of Secondary Education (GCSE) including maths and English (100% compared with the national average of 50.7%).

[9] St Ambrose College was the sixth out of 19 secondary schools in the borough in terms of proportion of pupils achieving at least five GCSEs A*–C (92%).

However, it was felt that this was too 'garish', so it transferred to the black blazers with the College shield emblazoned on the breast pocket, which is still worn to this day.

This was held at the Bridgewater Hall, and saw all of the last years academic certificates officially awarded, as well as performances by various student musical ensembles.

The alleged sexual abuse, including molestation of children while corporal punishment was administered, stemmed from 1962 onward to this day.

[21] On 15 July 2013, Alan Morris, a former teacher was charged with 41 counts of indecent assault following an investigation into historical sexual abuse at the school.

[25] Although no current staff were said to be involved in the abuse, in November 2014, two long-serving senior teachers at the school were suspended following allegations that they had knowledge of the crimes concerning Alan Morris at the time.
