Over-education definition
Over-education or ‘under-education’ means that workers have more or less education than that required by their job. ILO (2014) measure of education-occupation mismatch is based on a correspondence between the ISCED and ISCO classifications. Workers in a particular occupational group who have the assigned level of education are considered well matched, those with a higher (lower) level of education are considered overeducated (undereducated).
