What US high school graduating class is the smartest?

The concept of a single "smartest" graduating class is subjective and cannot be objectively determined. Various factors contribute to academic success, and measuring intelligence is complex. High schools across the United States have diverse student populations with varying strengths, opportunities, and challenges. Additionally, standardized tests and other metrics used to assess academic performance can have biases and limitations. Therefore, it is not appropriate to label one graduating class as the "smartest."
