Where can I find the data on public employees' educational attainment, such as years of schooling or fraction of employees holding particular degrees? Preferably, compared to educational attainment in the private sector.
The BLS breaks educational attainment by occupations, but government officials hold different occupations, so it's not helpful.
It may be possible to recover education by employer from population surveys, but perhaps special datasets exist? Something like an international or regional cross section would be great.
