Season 4 ended with Moesha and her friends graduating from high school and the finale marked Kim’s final appearance on the show. Kim was written out of the series by being accepted at Santa Monica College, while her friends made different plans and Moesha took a job at Vibe magazine. While not much was explained in the Season 4 finale of Kim’s departure and she hardly got a grandiose send-off, she did have an episode centered around her in which she explored her decision to attend college.
And in doing so, Kim went on to star in her Moesha spinoff, The Parkers. The show followed Kim as she attended college with her mom by her side, who had decided to go back to school along with her daughter. The series gave Kim the chance to shine on her own and, likely, helped bring peace to the Moesha set amid rumors of tempers and jealousy.
