Georgia Office of Student Achievement (GOSA) certified-personnel years-of-experience measures, compiled from local school systems' Certified/Classified Personnel Information (CPI) submissions. For every Georgia public school, school district, and the state as a whole, publishes the experience distribution of the certified-personnel roster for each of three employee groups (Administrators, PK-12 Teachers, Support Personnel): headcounts in five mutually exclusive experience bands (less than 1 year, 1-10, 11-20, 21-30, over 30 years) plus the mean years of experience. One row per school, district, or state per employee group per year; coverage runs from the 2010-11 school year through 2023-24. This is one of three topics derived from the same GOSA Certified Personnel source: `certified_personnel_composition` carries the staff headcount axes (certificate level, certification status, gender, employment status, race/ethnicity — including the total staff counts), and `certified_personnel_compensation` carries the FTE position counts and salary/contract-day measures.

**Filterable categorical columns** (comma-separated values union; multiple columns AND together):
- `employee_type` — one of: `administrators`, `pk_12_teachers`, `support_personnel`

**Detail levels available:** districts, schools, states (default: `schools`)

**Year coverage:** 2011–2024 (14 years, no gaps)

**NULL handling:** zero is a real value.

**Source:** Governor's Office of Student Achievement (GOSA)
