The 6`4”, 16-year-old centre-back is another success for the Moors academy.
He trained with the first-team last week and manager Mark Yates was very impressed with him.
Chisholm is a first-year student on the academy programme with CTC Kingshurst Academy.
He lives in Solihull and has had trials elsewhere in the past but only since joining up with Moors has his career started to take off.
He previously played for Wychall Wanderers and will be hoping to follow in the footsteps of Tyrese Shade (Leicester City), Kieran Dawes (Birmingham City), Marshall Willock (Chesterfield) and Josh Endall (Coventry City), all of whom have moved on to professional clubs from Moors academy this season.
