What the federal data cannot tell you

This site reports federal data about colleges. That data is unusually good — and it has clear limits. Knowing where those limits are is what separates using the numbers from being led by them.

What this data is good at

Federal college data is consistent across thousands of institutions, collected under a common definition, and published with its coverage periods. That makes it excellent for comparing colleges on cost, completion and earnings at a high level, and for narrowing a long list quickly.

What it cannot do

  • It cannot predict your outcome. Every figure is an average or median across a past cohort. Yours depends on your programme, your circumstances and your choices.
  • It cannot tell you about teaching quality. There is no federal measure of how well anything is taught.
  • It cannot tell you about campus life, support services, safety, or whether you would be happy there.
  • It cannot give you a current price. Cost figures cover a specific past award year and are already out of date when published.
  • It cannot tell you whether you will be admitted, or what aid you will be offered.
  • It cannot compare programmes reliably across colleges, because programme-level coverage is thin and definitions vary.

What to do with the numbers

Use them for the job they are good at: reducing a list, spotting outliers, and knowing which questions to ask. Then do the rest the way it has always been done — visit, talk to students and staff, ask the financial aid office for a real estimate, and check whether the programme you want actually exists in the form you want it.

  • Cross-check anything that will change your decision against the college’s own published figures.
  • Use each institution’s net price calculator for a personalised cost estimate — federal law requires one.
  • Ask about outcomes for the specific programme, not for the institution as a whole.
  • Treat a single number with suspicion, including ours.
