|Rabbi Chang is Señor Chang's older brother. They have a strained relationship because the Rabbi found his job at the time to be ridiculous since he is Chinese. He seems to be unaware of the irony as his own calling does not typically follow his ethnicity. It is unknown if he was aware that his brother was faking his Spanish knowledge. His first and so far only appearance was in the Season One episode "Basic Genealogy". He is portrayed by Tom Yi.|
On Greendale's special Family Day Event, Ben Chang is less then enthused that his brother will be visiting him. Later on the campus quad, a Family day BBQ is held and Rabbi Chang is introduced to Dean Pelton by his brother. Rabbi Chang tells him how ridiculous the idea of a Chinese Spanish teacher is. Señor Chang tells him that it's who is is and demands he accepts it. Later in the student lounge, he and his brother watch Pierce's unsuccessful attempt to draw a windmill while playing Pictionary. Pierce's sketch ends up resembling a swastika illiciting shock from the other players and outrage from Rabbi Chang.
He was held back by Ben who assured him he would take care of it. Sometime later, Officer Cackowski is interviewing all the parties involved who witnessed the fight that occurred between Señor Chang and Pierce over the drawing. Rabbi Chang is present but it's unclear whether he's proud of his brother for sticking up for his faith or disappointed that he got into a fight ("Basic Genealogy"). Several years later, his brother Ben's career as a teacher was over and he was now working as a Greendale security guard. Rabbi Chang managed to get him a freelance gig working as security for a Bar Mitzvah ("Contemporary Impressionists").
After seeing what looks like Pierce drawing a swastika:
- “What are you drawing?!”— Rabbi Chang
- “You're supposed to know stupid!”— Pierce
