Please assist me with the following sociology question:

Social promotion is the promoting of a student from one grade to the next even if he or she is failing courses. The rationale for social promotion is that moving students to the next grade prevents them from being stigmatized because they are older and bigger than other children in their classes. A number of cities have recently passed legislation banning the practice. In these cities, all students would be required to pass proficiency tests before they would be passed on to the next grade. In your opinion, what are the pros and cons of this change? Do you agree with it? Why?
