It's a new year at Abbott Elementary, and Janine is as eager as ever. She plans a district-wide initiative - Career Day - and is anxious for it to be a success. Meanwhile, Ava has a new approach to her job, and Melissa is asked a surprising question.

Gregory is hesitant when kids start hanging out in his classroom at lunch, looking to him for advice; Barbara is shocked to find Tariq is dating the mother of one of her students; Janine and Jacob try to hire an ASL interpreter.

Janine spearheads a pilot program that brings a librarian to Abbott; however, when friction arises with one of the teachers, it strains Janine's relationships with both parties. Meanwhile, both Melissa and Jacob deal with some big changes at home.

Ava and Gregory are invited to speak on a panel about public schools. Elsewhere, the other teachers must complete CPR training, and Janine faces challenges securing district approval for her librarian extension program.

Ava Fest is back, and with the help of the teachers, Ava’s set on outdoing last year by any means necessary. After Janine accepts the offer for a full-time position at the district, she just has to check off one last thing to make it official.

Two teachers head out on a double date, but when they run into familiar bar patrons, it proves to be an unfortunate distraction. At Ava’s first book club meeting, the group ends up in a debate over who would be the best post-apocalyptic leader.
