* School district: Funding levels, food service providers, and the types of meals offered significantly impact student satisfaction.
* School level: Elementary, middle, and high school students may have different preferences.
* Individual student preferences: Dietary restrictions, cultural backgrounds, and personal tastes play a large role.
* Survey methodology: The way a survey is conducted (e.g., anonymous vs. not, wording of questions) can affect the results.
While some surveys and studies have been conducted, they rarely represent a national average with a high degree of accuracy. You'll find varying percentages depending on the source, and any single percentage would be a generalization at best.
