Remaining single-sex until 1996, when Sixth Form admissions were opened to girls, the school transitioned to full co-education in the first decade of the 21st century.

Latymer's alumni include members of both Houses of Parliament, winners of Olympic medals, actors, musicians, and many figures in the arts and sciences.

[8] In 1628, a school, partially funded by the estate of Dr. Thomas Edwards, who had died in around 1618, was built for the Latymer boys in the churchyard in Fulham.

[11] The bishop of London, Frederick Temple, opened Latymer Upper School on its new site on King Street in 1895.

The buildings at the Weltje Road and King Street corner were purchased and adapted, with the addition of a biology laboratory and the arrangement of a top floor room as a chapel; this was consecrated in 1938.

[1] The school grew substantially in 1951 to over 1000 boys with the acquisition of Rivercourt House, beside the River Thames, extending the Latymer site southwards.

[1][13] The Direct Grant system was abolished in 1976, removing government funding,[14][15] Latymer became a public school, meaning that students normally paid fees.

[22] Each year, the school gathers in the nearby church of St Paul's, Hammersmith to celebrate "Founder's Day" in honour of Edward Latymer.

[26] The school provides many clubs and societies, including in 2024 a variety of sports, literature, dance, singing, debating, various technologies, philosophy, and photography.

[37] The Sports Centre was opened in March 2016; it has a six-lane swimming pool, basketball hoops, badminton markings, cricket nets, a fitness suite, and a bouldering wall, and serves as an area for pupils to take their examinations.

[39][40] The armorial bearings of the founder, Edward Latymer, included his Latin motto, Paulatim ergo certe ('Slowly therefore surely').

[41] In 2004 the school badge was simplified, dropping the motto, and retaining only the chevron on a blue field, with a single crosslet symbol.

[44] There were 29 Oxbridge places in 2021, and several pupils went to US universities such as Brown, Columbia, Dartmouth, Harvard, Princeton, Stanford, and Cornell.
