The 18-year-old defender will link up with Stocksbridge for the new season while continuing with Chesterfield's U23 setup.
Dolman made his first-team debut for the Spirerites in December 2022 in a 3-1 defeat to Coalville Town in the FA Trophy.
On his move to the Steels, he said: "I'm really happy to have signed for Stocksbridge, the management have been great.
"Hopefully I can contribute to help getting promotion this season."
