In December 2013 Sampson was appointed manager of the England women's team. In March 2015 England won the Cyprus Cup. In the 2015 FIFA Women's World Cup later in the year, he led England to the semi-finals, marking the first time England had won a match beyond the group stage of a World Cup. After losing the semi-final to Japan, England secured victory in the match for third place, beating Germany for the first time in 21 games. On 20 September 2017, Sampson was sacked as the manager of the England women's national team because of what the FA described as, "clear evidence of inappropriate and unacceptable behaviour by a coach" during his tenure as the manager of Bristol Academy prior to his appointment as England coach in 2014. An FA investigation into the allegations that led to his dismissal had concluded in 2014 that, "he did not pose a risk working in the game" but the decision to terminate his employment was taken when senior FA figures read the full report in 2017. This sacking followed FA investigations into allegations of racist behaviour and remarks by Sampson, brought by Eniola Aluko. The FA oversaw two investigations, the second of them an independent investigation by a barrister, Katharine Newton, which cleared Sampson. The FA reasserted, in their press release regarding his dismissal, that they continued to have confidence in those findings and his dismissal was unrelated to that issue saying, "In respect of investigations into specific allegations made by Eniola Aluko in 2016, The FA stands by the findings of the independent barrister Katharine Newton's investigation. Sampson subsequently brought an unfair dismissal case against the FA. On 18 October 2017, the FA apologised to players Eniola Aluko and Drew Spence after Katharine Newton concluded, on a balance of probabilities, in a third investigation that Mark Sampson made comments that were "discriminatory on the grounds of race". The FA agreed to pay a "significant " financial settlement to Sampson in January 2019, on the week his claim for unfair dismissal was due to be heard in court.
Stevenage
Mark Sampson was appointed as a first-team coach of Stevenage on 4 July 2019. Sampson was appointed as caretaker manager on 9 September 2019 after the sacking of Dino Maamria. Subsequently, Sampson was accused of using racist language in a coaches meeting by former first team coach Ali Uzunhasanoglu. Maamria also gave evidence against Sampson. The complaint was made a week after the meeting and after Uzunhasanoglu and Maamria had left the club. Stevenage denied the accusations, while the FA said they would investigate. On 20 November 2019 Sampson was charged by the FA for using racist language. On 15 December 2019 Stevenage announced that Graham Westley would return for this fourth stint as Stevenage's head coach, restoring Sampson to his previous role as a first team coach. During his oversight the club played 18 matches, winning five, with seven draws, and six losses. On 20 January 2020 the charge against Sampson of using racist language was dismissed as not proven by the FA independent commission. On 12 May 2020 Sampson confirmed he was taking legal action after the allegations were dismissed.
