Stockdale has been kept on after Moyes succeeded Sam Allardyce.
He told the Sunderland Echo: “I have been very fortunate, my pathway has been fantastic, coming through the Academy.
“I am a big supporter of our Academy, the job it does in aiding players is fantastic. It gets a lot of unfair criticism at times.
“You look at the senior team, there are Academy players dotted all the way through the squad.
“To work under Sam Allardyce, now England manager, and now under another exceptionally experienced manager is fantastic for my development.
“You are like a sponge, soaking things up all the time. Hopefully taking the team, I can put his ideas across."
