What F-33 actually measures
The NCES F-33 survey records district revenue and expenditure. PlainTeacher uses those records for measures such as per-pupil spending and instructional salary expenditure. A separate CCD Staff Universe file supplies the reported teacher headcount used in most district salary calculations.
Neither source reports open positions, applicant counts, time to hire, turnover reasons, subject-area certification, or whether a classroom is staffed by a long-term substitute. Those are the facts needed to establish a local shortage.
Source check: the NCES F-33 finance survey documents the finance file, while the NCES CCD staffing access point provides access to staffing records. Neither should be cited as a district vacancy file.
Why “shortage” needs a definition
Different sources may use the same word for different conditions: an unfilled posted role, an emergency credential, a vacancy after the school year begins, a low applicant pool, or a statewide certification area designation. Before comparing two claims, write down the unit, geography, role, date, and threshold used by each one.
A statewide shortage-area list also does not prove that every district has the same problem. Conversely, a district can have a hard-to-fill specialty even when its overall teacher headcount looks stable.
How finance data can generate a question
A district’s salary measure, enrollment, and spending can help select peers and identify an unusual pattern. For example, a district-level instructional salary measure below similarly sized in-state peers may justify checking its current schedule and vacancy history. It does not establish why the difference exists or whether hiring is difficult.
Keep the salary basis visible. PlainTeacher divides F-33 instructional salary expenditure by reported teacher headcount for most districts and uses an enrollment-based fallback for a small minority. The result is a comparative aggregate, not a current salary offer or a direct measure of teacher supply.
The confirmation stack
- State definition: find the current state education department’s shortage-area or workforce report and note its definition.
- District record: check dated vacancy postings, staffing reports, board packets, or public-record releases.
- Role detail: separate subject, grade, credential, and location rather than reporting one district-wide label.
- Time window: distinguish a current opening from a persistent pattern across reporting periods.
- Finance context: compare salary and spending only after the staffing fact is established.
Claims the data does not support
- “This district has a shortage” based only on a low salary or high student enrollment.
- “Pay caused the shortage” without evidence that rules out role, geography, working conditions, credential supply, or reporting differences.
- “The shortage is getting worse” from two finance releases that do not measure vacancies.
- “This district has enough teachers” because an aggregate headcount appears stable.
Frequently asked questions
Does F-33 report teacher vacancies?
No. F-33 is a district finance survey. It reports revenue and expenditure, not openings, applicants, turnover, certification area, or unfilled positions.
Can a salary estimate prove a teacher shortage?
No. It can identify a question worth investigating, but shortage requires current staffing evidence such as vacancy files, state reports, or district records.
Which sources should confirm the claim?
Use current state shortage reports, district vacancy postings, staffing reports, board records, and available turnover data. Record each source’s date and definition.
