| The International Standard Classification of Education (ISCED) is a scheme developed by the UN to provide a normalized, international set of values for classifying the level of a school or institution:
			0 = Pre-primary education
			1 = Primary education
			2 = Lower secondary education
			3 = (Upper) secondary education
			4 = Post-secondary education
			5 = First stage of tertiary education (not leading directly to an advanced research qualification)
			6 = Second stage of tertiary education (leading to an advanced research qualification) |
