7.49. The purpose of the International Standard Classification of Education (ISCED) is to provide an integrated and consistent statistical framework for the collection and reporting of internationally comparable education statistics. The coverage of ISCED 1997 extends to all organized and sustained learning opportunities for children, youth and adults, including those with special educational needs, irrespective of the institutions or organizations providing them or the form in which they are delivered.
7.50. ISCED is a multipurpose system, designed for education, policy analysis and decision‑making, whatever the structure of the national education systems and whatever the stage of economic development of a country. It can be utilized for statistics on many different aspects of education such as pupil enrolment, human or financial resources invested in education and educational attainment of the population. The basic concept and definitions of ISCED have therefore been designed to be universally valid and invariant with respect to the particular circumstances of a national education system. However, it is necessary for a general system to include definitions and instructions that cover the full range of education systems.
7.51. For instance, an employed person, when answering a question on highest completed level of general education at school, will base his or her response on the national classification system. Since education systems differ across countries, there is no unambiguous definition of general school education. Therefore, so that the goal of providing internationally comparable data can be achieved, as a first step, countries should use their own classification system and in a second step, where possible, a correspondence should be made with the internationally accepted International Standard Classification of Education (ISCED 1997).
7.52. ISCED 1997 identifies the following seven levels of education:
Level 0 - Pre‑primary education (provides a bridge between the home and a school‑based atmosphere)
Level 1 - Primary education or first stage of basic education (offers a sound basic education in reading, writing and mathematics along with an elementary understanding of other subjects)
Level 2 - Lower secondary or second stage of basic education (completes the provision of basic education which began at ISCED 1)
Level 3 – (Upper) secondary education (begins at the end of full‑time compulsory education)
Level 4 - Post‑secondary non‑tertiary education (captures programmes that straddle the boundary between upper‑secondary and post‑secondary education)
Level 5 - First stage of tertiary education (consists of tertiary programmes having an educational content more advanced than that offered at levels 3 and 4)
Level 6 - Second stage of tertiary education, leading to an advanced research qualification (reserved for tertiary programmes that lead to the award of an advanced research qualification)
