NBC has ordered a second season of its new midseason comedy series A.P.Bio, executive produced by Seth Meyers.

A.P. Bio was a big priority for NBC this midseason. The single-camera comedy got a major push with two special previews, including one after the Closing Ceremony of the PyeongChang Olympics. The series also got a digital promotional run ahead of its official premiere, which netted respectable sampling.

The high school comedy starring Glenn Howerton has not been a breakout. A.P. Bio is averaging a modest 1.2 rating in 18-49 and 3.7 million viewers overall in L+7 . But comedies are usually slow at the start and need time to grow. Plus, A.P. Bio has been relatively well received by critics, and it has been attracting highly educated audiences — the series indexes at a 149 among adults 18-49 with four or more years of college to rank #3 among primetime series on the Big 4 networks.

A.B. Bio has been the strongest ratings performer among NBC’s bubble comedy series that also include freshman Champions and sophomore Great News.

Written by SNL alum Mike O’Brien, A.P. Bio stars It’s Always Sunny In Philadelphia’s Howerton as disgraced Harvard philosophy scholar Jack Griffin who, after losing out on his dream job, is forced to return to Toledo, Ohio, and work as a high school Advanced Placement biology teacher. As he comes crashing in to Whitlock High School, Jack makes it absolutely clear he will not be teaching any biology. Realizing he has a room full of honor roll students at his disposal, Jack decides instead to use the kids for his own benefit.

Patton Oswalt, Lyric Lewis, Mary Sohn, Jean Villepique, Tom Bennett, Paula Pell, Charlie McCrackin, Jacob McCarthy, Aparna Brielle, Nick Peine, Allisyn Ashley Arm, Eddie Leavy, Jacob Houston, Sari Arambulo, Tucker Albrizzi and Spence Moore II co-star.

O’Brien executive produces with Seth Meyers, Mike Shoemaker, Andrew Singer and Lorne Michaels. A.P. Bio is produced by Universal Television, Broadway Video and Sethmaker Shoemeyers Productions.
