Definitions, Sources and Footnotes
Find definitions, sources and footnotes for SREB's compilation of state and regional teacher data.
While teacher workforce data is currently a collection of imperfect and sometimes proxy measures, it does provide a glimpse of information about the status of the profession related to quantity, preparation, demographics, shortage areas, quality, and the distribution of talent.
For state reported data, SREB pulled the most comparable data available. Certain states do not report all data points or define certain data points differently. These are noted by state in the list below. Some percentage totals are off due to inconsistencies in data reporting or rounding errors in data files.
Use the accordions below to find definitions, sources, and footnotes for SREB’s compilation of teacher workforce data.
Common Definitions
Uncertified Teachers: Teachers who have not met full credentialing requirements as set by the state. This includes emergency, provisional, and limited certifications.
Out-of-Field Teachers: Teachers who are teaching courses outside of their certified subject areas.
Inexperienced Teachers: Generally defined as teachers who have less than three years of experience. Select states alter this definition. See state-by-state footnotes below.
Attrition or Turnover Rate: The percentage of teachers not retained from the previous year in the state’s education system.

Going forward, we will share the number of NBCTs with active certifications, as well as the number who ever achieved certification, in state rankings.
