Most people assume that reading a college ranking is straightforward: you look at the list, see where a school falls, and draw a conclusion.

But in reality, rankings are not conclusions, they are compressed models of complex systems.

Choosing colleges often starts with excitement and quickly turns into information overload. Students are asked to compare rankings, majors, tuition costs, acceptance rates, campus culture, scholarships, internships, location, outcomes, and dozens of other factors, often all at once.

For decades, college rankings have played a major role in how students, families, and even institutions evaluate higher education. Most of these rankings follow a familiar model: a single master list that attempts to compress hundreds of universities into one ordered hierarchy.
