Cory's mom, Tanya Baxter, is not present in Cory in the House because her character moved to England to attend law school.
Tanya Baxter's Absence Explained
Cory Baxter's mother, Tanya Baxter, does not appear in the spin-off series Cory in the House because her character was written out to pursue a significant personal goal. Within the show's narrative, Tanya relocates to England to attend law school, which explains her absence from the White House, where Cory and his father, Victor Baxter, move.
This narrative decision allowed the spin-off to focus on Cory and Victor's new life in Washington D.C. while maintaining character continuity within the broader series universe. Although not physically present in Cory in the House, Tanya's character was still acknowledged. For example, she is mentioned in the Raven's Home episode "Dancing Tween," further confirming her continued existence in the storyline even after her departure. This storyline development provided a logical reason for her absence, facilitating new character dynamics and plotlines central to Cory in the House.
