This sounds like linear interpolation: see -ipolate-.
Panel data should be interpolated separately -by <panelid>:-.
But note that if "education" means something like "years
of education", then that case too is discussed in the
FAQ you cite in its last section, at least for people
who stay in the system and progress a year at a time.
People who repeat a year or take years out of the system
are naturally a complication.
