Behind the median
Everyone here with an Eng Scorer read, placed in their caliber tier.
- 9%Strong or solid6 people
- 57%Emerging40 people
- 34%Unproven24 people
70 of the 70 people here carry an Eng Scorer tier.
Exceptional and strong are the top two of the five tiers. Fewer than 3 of the 70 people here with a read sit in them, which is too few to print as a count. 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.
Whether a title rose here

44 of the 70 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 44 of the 70 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.

9 of the 70 people here whose profile was checked for public accounts. An account the check did not find reads the same as no account, so this is a floor rather than a census.
