Behind the median

Everyone here with an Eng Scorer read, placed in their caliber tier.

  • 8%Strong3 people
  • 54%Solid20 people
  • 38%Emerging or unproven14 people

37 of the 75 people here carry an Eng Scorer tier.

3 of the 37 people here with a read sit in exceptional or strong, the top two of the five tiers, 8%. A tier is the band a caliber score falls in, so this is the same measurement as the median on the caliber card, opened up. A tier holding fewer than 3 people is printed with the one next to it, because that few is a person rather than a pattern.

20 of the 75 people here whose profile was checked for public accounts. An account the check missed reads the same as no account, so this is a floor.
