West Brom will retain coaches Michael Appleton and Keith Downing until the end of the season after both impressed new manager Roy Hodgson.
Appleton and Downing were promoted to assistant head coach and first team coach respectively last month.
Their appointments followed the departure of Roberto Di Matteo as Baggies manager on 6 February.
"It has gone as smoothly as it possibly could and a lot of thanks goes to Michael and Keith," said Hodgson.
Di Matteo was relieved of his duties and put on gardening leave after a run of 13 defeats in 18 games.
The Baggies, 16th in the Premier League and only one point adrift of the relegation zone, are still facing the prospect of Championship football next season but results have improved under Hodgson.
They are unbeaten during the former Liverpool manager's four-game tenure and the 63-year-old said: "I see no reason to change anything for the remainder of the season.
"In the summer we will look at things again when there is more time to assess everything."
