What is the largest middle school in US?

There's no definitive answer to what the largest middle school in the US is. School size data isn't centrally tracked and consistently defined across all states. "Middle school" itself can also encompass varying grade ranges (e.g., 6-8, 7-8, etc.). Therefore, any claim of the "largest" would be difficult to verify and likely depend on the criteria used (student enrollment, building size, etc.).
