How much of each district is administrators rather than teachers, how much of its budget goes to administration, and how much of both is explained by district size.

The two administrator categories added together, divided by every staff category the district reported that school year, —. Full-time equivalent positions, not people and not dollars. Sorted lowest to highest.
Source: CT State Department of Education, EdSight FTE Staffing report, October 1 collection, via administration.json (staffing.groups.admin_central + admin_school ÷ every reported group). The numerator is the state’s own categories “Administrators, Coordinators and Department Chairs — District Central Office” and “… — School Level”; grouping the remaining categories into a denominator is this site’s decision and the payload names every source category in each group. A category with no row in a year is a gap, so a district’s share is of the categories it actually reported.
One point per district: October 1 enrollment on the horizontal axis (a logarithmic scale, because enrollment runs from a few dozen students to almost twenty thousand), administrator share of staff on the vertical. The dashed line is a least-squares fit of the share on the logarithm of enrollment — it describes these points, and it is not a target any district should be at. The box below reports how much of the spread in the share the fit accounts for, and gives the same answer a second way, as the observed median share in each quarter of districts by size.
Source: both axes from EdSight via administration.json — vertical, the administrator share described above; horizontal, staffing.enrollment, the October 1 headcount for the same district and the same school year. The two axes therefore share a source and a year, which the income scatter elsewhere on this site cannot claim. The fit is a description of the points plotted and not a prediction for any district; size is one influence among many, and a district above the line is not thereby overstaffed.
General administration — the board of education and the superintendent’s office — plus school-based administration, the principals’ offices, divided by total expenditures, —. Dollars on a fiscal-year basis from a different state collection than the staffing charts above; the two are never added or placed on one axis. These functions pay for more than administrators: the salaries of the clerical staff in those offices, and their supplies and services, are inside them too.
Source: CT State Department of Education, Education Financial System, Per Pupil Expenditures by Function (District), via administration.json (spending.general_admin + school_admin ÷ spending.total). Districts file these figures through the state’s uniform chart of accounts, so what falls under each function is defined the same way for every district; how a district staffs and organises those offices is not.
October 1 enrollment divided by the administrator count, —. Rank 1 is the fewest students per administrator, which is the same end of the list as the highest administrator share — the measure is inverted relative to the chart above, and the sort is not. It is a ratio of two reported totals and says nothing about what any administrator does.
Source: EdSight via administration.json — staffing.enrollment ÷ (admin_central + admin_school), same district and same school year. Not a caseload, not a span of control, and not a figure the state publishes.

Every figure above counts positions or dollars by function. None of them is a salary, because Connecticut publishes no district-by-district administrator or teacher salary data. EdSight’s educator reports cover diversity, preparation, staffing levels, attendance, vacancies and attrition — and nothing on pay.
Two records routes exist and both are being worked. Under Conn. Gen. Stat. § 10-153d(b) every board of education must file a signed copy of each teacher and administrator contract with the town clerk and with the Commissioner of Education, so the salary schedules for all ~180 teacher units and ~130 administrator units sit in one place at the State Department of Education. Superintendent contracts are not bargaining-unit agreements and are not filed there; each one is a separate request to its own board.
When those schedules are in hand this page will carry them beside the counts, because the two answer different halves of the same question: a district with fewer, better-paid administrators can spend more on administration than one with more of them. Until then, no salary figure appears here at all rather than an estimate standing in for one.
Administrator share of staff = (district central office administrators + school-level administrators) ÷ every staff category the district reported that school year, in full-time equivalent positions. Administration share of spending = (general administration + school-based administration) ÷ total expenditures, for the fiscal year named on the chart. Students per administrator = October 1 enrollment ÷ the administrator count.
The measures are computed in your browser by shared/administration-metrics.njk, the one definition this page and every town’s own administration page both read. The payload is built by Data/build_administration.py; METHODOLOGY.md carries the full method and PLAN-ADMINISTRATION.md the sourcing plan.
