The Educational and Training Services Branch can trace its history back to 1762 when the First Regiment of Guards (Grenadiers) based at the Tower of London established a Unit School.

[3] Thus, the Corps of Army Schoolmasters was established in 1845[4] to provide Education for Soldiers and their families.

[6] Members of the ETS Branch are entitled to wear blue socks with their Number 2 Service Dress (British Army) uniforms; this is a unique part of their uniform, as a variation of socks is not seen in other units which wear infantry pattern service dress.

[7] This stems from a Royal Warrant of 1854 which instructed Army Schoolmasters to wear: "a blue frock-coat, heavily braided in black, and worn with gold shoulder-knots, a sword and a crimson silk sash, and a cap with scarlet band, bearing a crown in gold thread".

[18] The Educational and Training Services Branch is a member of the International Association for Military Pedagogy (IAMP).
