Jack Rimmer (Jason Merrells, series 1−3, 15–) is the headteacher of Waterloo Road from the start of the series, who initially assumes the position in an acting capacity after his predecessor's public breakdown. His efforts to turn the school around face various challenges, and his confrontational style causes consternation. He has romantic liaisons with Steph Haydock and LEA inspector Heather Davenport, and a more serious relationship with Davina Shackleton. In series 3, after witnessing Izzie Redpath's death he finds it increasingly difficult to cope with the pressures of running the school, and resigns with immediate effect after being reprimanded for financial mismanagement. He briefly returns later in series 3 in an attempt to win Davina back, but she chooses to remain with Tom. In series 15 Jack returns as a counsellor, having left teaching in the intervening years. After becoming his client, Stella Drake offers Jack a job leading the school's renewed pastoral care provision. After a chance meeting with Darius Donovan at an addiction support group, Jack suggests to Stella that Darius may not be ready for more responsibility. Jack accepts the Deputy Head position to prevent Darius from being promoted, but starts drinking again to cope. He discovers that Darius is covering up his part in Stella's granddaughter's death, and punches Darius. With his drinking uncovered, his accusations against Darius go unheard and he is forced to leave the school. He later returns after entering recovery, makes amends with Stella and helps to uncover Darius's criminal activity. In series 18, he rejoins the staff as an English teacher.

Following a slow-burning flirtation with Andrew Treneman she decides to join him in Rwanda, but returns to Rochdale and her old job during series 4. Her return is tainted by the revelation that her baby daughter was illegally adopted. She subsequently falls into an ill-fated relationship with Max Tyler, from which she falls pregnant, and leaves the school following the birth of her son, Dexter.

She is hit hard by the arrest of pupil Danny Lewis for knife crime, and his later death on school grounds, but finds solace in her reunion with Andrew.
