Black was appointed joint assistant-manager of the
Kirkcaldy side in 2001. Managerial changes saw him leave
Starks Park in early 2002 but he found a new position as assistant to former Airdrie teammate
Sandy Stewart at
Airdrie United, the reincarnation of
Airdrieonians, later that year. Black left
Airdrie United for
Leicester City in 2004, gaining a coaching position under
Craig Levein. His contract at the
Walkers Stadium ended when Levein was sacked in 2006 and he sealed a return to Airdrie later that year, this time as manager. Black guided the team to the
2008–09 Scottish Challenge Cup. He lost four First Division v Second Division promotion play-off games over the course of his tenure. On the evening of 15 June 2010, the website of The Airdrie and Coatbridge Advertiser reported that despite no official statement from the club, Black had "parted company" with Airdrie United. A few days later it was confirmed by the club that Black had been "relieved of his duties". Events took a twist on 23 June however, as the BBC reported that Black and the club had failed to agree on a compensation deal to cover the remaining two years on his contract, and that Black was still being paid. Black was said to be seeking legal advice on the matter. On 15 July 2010, it was announced that Black had been appointed as an assistant coach at the
Scotland national team, and that he had come to an agreement with Airdrie United over compensation. On 19 January 2011, Black was appointed assistant manager at
Motherwell. Black and manager
Stuart McCall guided the club to high league finishes in 2011–12 (third place), 2012–13 (second) and 2013–14 (second). Black was appointed as caretaker manager on 2 November 2014 after McCall resigned. He was in charge for five matches, and initially stayed on as Motherwell's assistant when
Ian Baraclough was appointed manager, but was sacked on 6 February 2015. On 12 March 2015, Black again joined forces with McCall as assistant manager at Rangers; they left two months later when the club failed to gain promotion. On 21 June 2016, Kenny Black was confirmed as assistant manager to Stuart McCall at Bradford City in the English League Division One. He left in February 2018. On 4 February 2020, he returned to
Valley Parade as assistant to McCall for a second time. ==Honours==
