Looking for the name and author of this book or story?

I read a book or story in my grade 9 English class about forcing equality. (Or the danger of not appreciating each person for his or her individual strengths in an attempt to achieve true equality)

In this world of equality, if a person was smart, he was forced to wear apparatus on his head that would give him an electric jolt to short circuit his mental activity so that he wouldn't be smarter than the person with the most severe challenges.

If a person was strong, healthy, and athletic, he was forced to wear heavy weights in order to hold him back so that he couldn't perform better than the person with the most severe physical limitations.

If anyone knows what the name of this book (or story) and/or author might be, please respond. It has been driving me bonkers for years trying to think of the title!!!
