RM plc is a British company that specialises in providing information technology products and services to educational organisations and establishments.

As of 2016[update], RM plc employs around 1,700 people, the majority based in the company's headquarters located on Milton Park, near Didcot, Oxfordshire.

RM also has offices across the United Kingdom (Cheshire, Nottinghamshire, Lanarkshire and London) and a software development facility in India.

The company was invited to tender to supply the BBC micro[14] but declined on grounds that it was not economically feasible to provide so many features at such a low price and to such a tight schedule.

[17] Previous CEOs were: Mike Fischer (until 1997), Richard Girling (1997–2002), Tim Pearson (2002–2008), Terry Sweeney (2008–2011),[18] Rob Sirs (2011–2012),[19][20] Martyn Ratcliffe (2011–13),[21] David Brooks (2013–2021),[22][23] and Neil Martin (2021–2023).

Despite a pilot phase in 2005 involving 45,500 pupils that was judged a success by the Qualifications and Curriculum Authority[24] the government cancelled the contract in 2007, shortly before their scheduled introduction.

[25] Cuts in the budgets of UK educational establishments in 2011 damaged RM's revenues, leading it to shed hundreds of employees and sell less profitable parts of its business.

[42] A contraction in customer spending in RM's core UK education market and slow growth in the overseas businesses prompted it to divest several of them from 2010.

[43] In 1993 the company established a subsidiary in Soest, Germany, in order to sell a localized version of RM Net LM, a turnkey Local Area Network product for schools, consisting of file-servers running Microsoft LAN Manager, client PCs running Microsoft Windows 3.1 and including a suite of RM-developed network management applications.

The company grew to employ 50 staff located in Perth, Melbourne, Sydney and Wellington (NZ), servicing over 4,000 schools across Australasia and in Hong Kong, Beijing, Shanghai, Singapore and Taipei.

A common use for the AX was as a fileserver, connected to PC-186 clients using MS-Net, Microsoft's network operating system of the time.

RM's fileserver platform became its 'E Series' computers, using the similarly short-lived EISA architecture and using a tower case to allow space for multiple hard disks.

The success of PC compatibility as a worldwide standard changed RM's focus from complete in-house design of circuit boards, peripherals and firmware to the assembly and integration of hardware components sourced predominantly from the Far East.

[52] In 2005 RM was awarded the contract for Glow (formally known as Scottish Schools Digital Network (SSDN) National Intranet project).
