Behind the median
Everyone here with an Eng Scorer read, placed in their caliber tier.
- 12%Exceptional4 people
- 18%Strong6 people
- 47%Solid16 people
- 24%Emerging8 people
34 of the 34 people here carry an Eng Scorer tier.
Exceptional and strong are the top two of the five tiers. 10 of the 34 people here with a read sit in them, 29%. 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.
Whether a title rose here
The level of the first title recorded here, against the last.
45%Titles that rose14 of 31 classified people
- 45%Rose14 people
- 55%Stayed level or fell17 people
31 of the 34 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 who recorded one title here and then left, it is 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. A title that matches no rung is left out rather than guessed, and product, program and project managers are left out entirely, being a different ladder. That leaves 31 of the 34 people here classified, and it leans towards people who have left: someone still here on a single recorded title has nothing to be measured against. A direction 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.
