Since airing, the episode has received positive reviews from television critics, with Hoffman's performance being critically lauded. The authors of the book I Can't Believe It's a Bigger and Better Updated Unofficial Simpsons Guide, Warren Martyn and Adrian Wood, said "Despite a scene-stealing performance from Ms Krabappel, this is Lisa's show. Mr Bergstrom's last message for Lisa is a delightful touch and adds the finishing touch to a wonderful episode." Former TV Squad blogger Adam Finley named "Lisa's Substitute" as one of his top fourteen most touching The Simpsons episodes, and The Simpsons Archive webmaster Jouni Paakkinen rated the episode as his third favorite.
