Paul Hart was confirmed on Tuesday as Portsmouth's manager until the end of the season.
Brian Kidd will stay on as first-team coach. Hart replaced Tony Adams last month.
Executive Chairman Peter Storrie told the club website: "(Owner) Sacha (Gaydamak) and I have been delighted with how the team have fared under Paul's and Brian's control. They both have so much experience in the game, and they have the respect of the players."
He said that the "managerial situation" would be reviewed "again at the end of the season."
Portsmouth had won one and drawn one under Hart before Tuesday's 1-0 defeat to Chelsea, reported dpa
