The series being released a few months after the Nth room case opened, director Kim said that "the incident was so shocking that [he] felt frightened. Extracurricular could become an opportunity to discuss this uncomfortable reality. As a creator, [he] felt [he] had to deal with the issues of our society with more depth and responsibility."
On April 29, some of the cast and crew attended a special one-day class by Professors Kwon Il-yong (South Korea's first profiler), Park Mi-rang (a criminologist) and Seo Min-soo (from the Police Human Resources Development Institute), which was broadcast live on Netflix Korea's YouTube and V Live channels. They discussed the reality of youth crime in society.

Extracurricular was the ninth most-watched South Korean series on Netflix in 2020.
John Serba of Decider said that "Extracurricular is good, funny stuff. The debut episode's near-miss ending isn't entirely satisfying, but that's not likely to stop you from binging the crap out of this show."
The series has also "gained rave reviews for its clear depiction of the struggles of teenage students."
