I'm pretty sure the definition has changed then. My mother told me that adjunkt was a teacher with 5 years of education (there was something about a mix of mellomfag and hovedfag too), lektor was 7 years of education, and 6 years of education (which was what she had) was "adjunkt med opprykk". She never taught below gymnas (i.e. high school) level.

Ah yes, simplified a bit to much here. You are certainly rigth, they can teach at qny lecture level but below university level.
