The following statements explain why grades are important:
- Grades provide a way for students to reflect on what they have learned.
- Grades give employers and colleges a way to judge students’ potential.
- Good grades ensure that students can get scholarships to go to college.
- Good grades are often required for participation in extracurricular activities.
- Grades give teachers an idea of how well students know the lesson content.
The statement "Grades determine whether students will succeed in after-school jobs" is less universally applicable, as success in jobs can depend on many factors beyond grades.
