Behind the median

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

  • 32%Strong or solid12 people
  • 68%Emerging or unproven26 people

38 of the 38 people here carry an Eng Scorer tier.

Exceptional and strong are the top two of the five tiers. Fewer than 3 of the 38 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

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

59%Titles that rose16 of 27 classified people

  • 59%Rose16 people
  • 41%Stayed level11 people

27 of the 38 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 27 of the 38 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.

Where they studied

Not enough education on the record here.All 38 people here have a school on file, but no single school is listed by as many as 3 of them, and 3 is the fewest this map will count.

Public work

17 of the 38 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.

Across the 325 companies on the map that can show this figure, the median is 38%.

Where they are now

89% of the people who have worked at Justworks and list a location live in New York today, against 33% of everyone on the map.

Where they live now, from the profile as it reads today, not where they sat while they worked at Justworks: a metro here does not mean the company has an office in it. The lower strip is the same metros across the whole map, for comparison.
