The cast of Abbott Elementary has been working hard at Willard R. Abbott Elementary, but no one more than second-grade teacher Janine Teagues.

The main cast has remained mostly the same since the comedy's inception.

Quinta Brunson stepped in a different light as we saw her work in her new role as a temporary fellowship in the school district.

This gave Season 3 a little twist, following her trying to adjust to bureaucracy and her co-workers' happenings.

The cast brings mightier humor to our TV screens each new season.
