ISLED

(International Standard Level of Education)

ISLED (International Standard Level of Education) is a one-dimensional score for level of education created by Harry B.G. Ganzeboom and Heike Schröder. The methodology used to derive an ISLED score is similar to the one used to construct the International Socio-Economic Index of occupational status [ISEI].
