Behind the median
Everyone here with an Eng Scorer read, placed in their caliber tier.
- 19%Exceptional or strong6 people
- 48%Solid15 people
- 32%Emerging10 people
31 of the 31 people here carry an Eng Scorer tier.
Exceptional and strong are the top two of the five tiers. 6 of the 31 people here with a read sit in them, 19%. A tier is the band an Eng Scorer 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 together with the one next to it, because a bucket that small is a person rather than a pattern.
