Behind the median
Everyone here with an Eng Scorer read, placed in their caliber tier.
- 14%Strong5 people
- 16%Solid6 people
- 59%Emerging22 people
- 11%Unproven4 people
37 of the 37 people here carry an Eng Scorer tier.
Exceptional and strong are the top two of the five tiers. 5 of the 37 people here with a read sit in them, 14%. 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.

24 of the 37 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 24 of the 37 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.
