Josh made his senior debut for the club off the bench in Albion's Emirates FA Cup clash against Aldershot in January 2024.
Shaw was rewarded for his impressive displays at a higher age level by signing his first professional deal at The Hawthorns.
Josh agreed a two-year-deal in the summer of 2022 after showing his qualities in Richard Beale's Under-21s during the 2021/22 campaign.
The left-sided youngster spent his early years in the game at Merseyside outfit Everton, but the Baggies gave him the opportunity to continue his development as a first-year scholar.
The Manchester-born defender operates on the left wing, mainly as a left-back, but has enjoyed the freedom of playing as a No.11 during his time in B71.
Shaw's progress both technically and mentally continued to gather momentum when he gained numerous opportunities to impress in Albion's PL2 side during the 2021/22 campaign.
He came off the bench for his first appearance against Nottingham Forest in October, before making his first start in the 23s during the Baggies' 4-1 PL Cup away win over Arsenal.
Albion's talented academy star went on to make 14 appearances in the Under-23s that year in the PL2 Division 2 and Premier League Cup, which included star performances against the Gunners and local rivals Aston Villa.
