CASPer Quartiles

Understand what your quartile means and what it does not mean.

01

Quartiles are ranges, not exact scores

A first-quartile result indicates the lowest comparative band and a fourth-quartile result indicates the highest. A quartile does not tell you your exact score, percentile, or how close you were to the next band.

02

How to interpret each band

  • Fourth quartile: strong relative performance, but not an admission guarantee.
  • Third quartile: above the midpoint of the comparison group.
  • Second quartile: below the midpoint, with substantial overlap in practical ability near band boundaries.
  • First quartile: a signal to review response quality and timing, not a verdict on your suitability for a profession.
03

What can lower a result

  • Failing to answer the exact question.
  • Making confident assumptions when the scenario leaves important facts unknown.
  • Using empathy statements without making a decision.
  • Escalating immediately when a private, lower-risk intervention would be appropriate.
  • Leaving responses unfinished because the opening is too long.
04

A better improvement target

Instead of chasing a quartile, track observable response habits: time to reach a decision, number of relevant stakeholders considered, whether conditions are explicit, and whether the final action is concrete. Those measures are trainable even when the official score is not visible.

Frequently asked questions

Is fourth quartile a perfect CASPer score?

No. It is the highest broad comparative band, not a perfect score.

Can I get admitted with a first- or second-quartile CASPer result?

Admissions decisions depend on the program and the rest of the application. A quartile alone cannot determine the outcome.
