Behind the median

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

  • 5%Exceptional or strong8 people
  • 31%Solid48 people
  • 50%Emerging78 people
  • 14%Unproven22 people

156 of the 425 people here carry an Eng Scorer tier.

8 of the 156 people here with a read sit in exceptional or strong, the top two of the five tiers, 5%. 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. A tier holding fewer than 3 people is printed with the one next to it, because that few is a person rather than a pattern.

Whether a title rose here

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

35%Titles that rose110 of 312 classified people

  • 35%Rose110 people
  • 54%Stayed level169 people
  • 11%Fell33 people

312 of the 425 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.
