Behind the median
Everyone here with an Eng Scorer read, placed in their caliber tier.
- 15%Exceptional12 people
- 51%Strong41 people
- 21%Solid17 people
- 13%Emerging10 people
80 of the 109 people here carry an Eng Scorer tier.
53 of the 80 people here with a read sit in exceptional or strong, the top two of the five tiers, 66%. 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.
Whether a title rose here
The level of the first title recorded here, against the last.
53%Titles that rose34 of 64 classified people
- 53%Rose34 people
- 47%Stayed level or fell30 people
64 of the 109 people here had a title that could be placed on the ladder before and after.
A title rose when the last title recorded here sits higher on the ladder than the first. For someone with one title here who then left, it's measured against the first title of their next role. The ladder runs intern, junior, mid, senior, staff or manager, principal, director, VP, then founder or C-level. Titles that match no rung are left out rather than guessed, and product, program and project managers are left out entirely as a different ladder. What's left leans towards people who have left: someone still here on one recorded title has nothing to measure against. A direction holding fewer than 3 people is printed with the one next to it, because that few is a person rather than a pattern.
