 Since airing, the episode has received mostly positive reviews from television critics. The authors of the book I Can 't Believe It's a Bigger and Better Updated Unofficial Simpsons Guide, Warren Martyn and Adrian Wood, thought the episode displayed The Simpsons "at its best – not only hilarious but daringly outspoken on a whole range of issues – the failures of the education system, police abuses of power, the stifling of children's creativity." Bill Gibron of DVD Verdict said "Separate Vocations" represent The Simpsons "at its apex as a well tuned talent machine grinding out the good stuff with surprising accuracy and skill." Gibron added that the episode shows that "even in territory they're not used to (Bart as a safety patrol, Lisa as a cursing class cut up), the Simpsons'kids are funny and inventive." Nate Meyers of Digitally Obsessed gave the episode a four out of five rating and commented that the script's "departure from the traditional roles assigned to Bart and Lisa makes for a fresh experience with many laughs." Meyers thought the highlight of the episode was Bart's ride in the police car. DVD Movie Guide's Colin Jacobson thought the theme of the episode was unoriginal, but commented that Bart's "rapid embrace of fascism" and Lisa's "descent into hooliganism" provide "a number of funny opportunities, and 'Separate Vocations' exploits them well. Though it ’ s not one of the year ’ s best shows, it seems like a good one for the most part."
