Marx Arriaga participated in a march with the CNTE teachers' union, calling for a "refounding" of the Ministry of Public Education (SEP) and the resignation of Mario Delgado. Arriaga claims the SEP fails to adhere to the goals and principles of the New Mexican School (NEM) and disrespects the educational model.

Esto al asegurar que la SEP no cumple con el objetivo y principios de la Nueva Escuela Mexicana (NEM), pues no hay respeto por el modelo educativo.
