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.

After a student is caught smoking, the Abbott staff come together to revamp the outdated drug policy. Meanwhile, Janine tries to prep the new substitute teacher for her class but finds it challenging to give up her former role.

Jacob is shocked when he finds out his colleagues are not invested in his frequent email messages and haven’t even been writing their own replies. Meanwhile, Gregory turns to Janine for help with a former student.

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.

Jacob manages to pull off a schoolwide field trip to the park; however, when Abbott must share the playground, the fun and games turn competitive. Elsewhere, Mr. Johnson enjoys having an empty school to himself.

It’s the last day of school! Ahead of summer vacation, Janine throws the perfect end-of-year party for her colleagues and friends, taking all their interests into consideration.
