Behind the median

Everyone here with an Eng Scorer read, placed in their caliber tier.

  • 4%Exceptional or strong17 people
  • 18%Solid67 people
  • 58%Emerging220 people
  • 20%Unproven78 people

382 of the 382 people here carry an Eng Scorer tier.

Exceptional and strong are the top two of the five tiers. 17 of the 382 people here with a read sit in them, 4%. 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

The level of the first title recorded here, against the last.

37%Titles that rose117 of 315 classified people

  • 37%Rose117 people
  • 57%Stayed level180 people
  • 6%Fell18 people

315 of the 382 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 315 of the 382 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.
