Premier League referees' chief Keith Hackett praised his new hire, brushing aside worries that Attwell will be unable to effectively take charge of matches featuring players who are older than him.
"Last season week-in week-out he produced consistent, high quality performances. Under pressure he remained calm and showed a great deal of maturity when managing players," said Hackett of Attwell's lower division work.
Attwell's most important game thus far came at the end of last season when he officiated the League Two playoff final at Wembley.
When he does make his top-flight debut, Attwell will break the mark set by a 29-year-old Mark Clattenburg in 2004.
In addition to his Premier League job, Attwell holds a degree in sports science and works for UK Sport.
