Academic success is a complex issue with no single person solely responsible. Both parents and teachers play crucial, but different, roles. While parents are responsible for the home environment and instilling good study habits, teachers are responsible for providing instruction and assessment in the classroom. The student themselves also plays a crucial role in their own success through motivation, effort, and engagement.
Ultimately, a successful academic experience requires a collaborative effort between the student, parents, and teachers. Blaming one party over the other is unproductive.
