Which character becomes a teacher at Edward J. Tilghman Middle School?

Roland "Prez" Pryzbylewski becomes a teacher at Edward J. Tilghman Middle School.

In The Wire, Prez begins as a Baltimore police officer whose early career includes work in the detail investigating drug cases. After leaving the department, he changes direction and starts training to become a math teacher. He is assigned to Tilghman Middle School, the central setting of the show's fourth season.

The role gives Prez a new perspective on Baltimore's institutions. As a former detective, he initially expects preparation, rules, and authority to be enough, but his students' difficult circumstances quickly challenge those assumptions. He gradually becomes more attentive to their individual needs and develops into one of the show's more sympathetic educators.

A common mix-up is confusing Prez with other major police characters. Jimmy McNulty, Bunk Moreland, and Kima Greggs remain associated with police work; none becomes Tilghman's teacher. Prez is played by Jim True-Frost, and his teaching career continues into the show's fifth season.
