It’s 1990-something, and since Lainey still hasn’t achieved rock ‘n’ roll greatness, she returns to William Penn Academy as the new music teacher. Lainey has a hard time adjusting to being an authority figure, but she realizes she might not be so bad at it when she discovers a kindred spirit in Principal Glascott’s niece, Felicia. Meanwhile, Coach Mellor struggles with Michael Jordan’s influence on modern-day basketball.

Hoping to gain respect among her colleagues at school, Lainey (AJ Michalka) comes up with a misguided plan to give an awkward and insecure student a full makeover; Principal Glascott (Tim Meadows) and Coach Mellor (Bryan Callen) take friendly competition to a new level. Guest starring Ana Gasteyer.

Lainey (AJ Michalka) and Glascott (Tim Meadows) encounter an overbearing parent and enlist the help of Beverly Goldberg (guest star Wendi McLendon-Covey); Mellor (Bryan Callen) realizes he might want to be a father after CB (Brett Dier) shows him how to care for confiscated digital pets.

Coach Mellor cracks down on cheating, which leads him to take on the failing mathletes for the upcoming Math Olympiad; Lainey helps C.B. deal with a challenging student.

After Mellor tells Lainey that sports are king at William Penn, she sets out to put on the Broadway hit musical “Rent” to show Mellor the arts are just as important as athletics. Meanwhile, Glascott and CB struggle to modernize the school’s outdated boy’s health education program.

When Lainey starts to teach the easy A course for jocks, Coach Mellor challenges her to expect more from his athletes. After CB points out Felicia needs to beef up her resume for college, Glascott bribes his niece to run for class president.
