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.

When Barbara's church choir uses the gym for rehearsals, Ava notices tension in the group. Jacob's eagerness for a full social calendar worries Gregory. Melissa and Janine investigate a new substitute.

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.

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.
