The classification of ECEC settings as pre-primary or serving children under age 3, as well as the other levels of education described in the volume, is based on the International Standard Classification of Education (ISCED). ISCED is an instrument for compiling statistics on education internationally. ISCED‑2011 is the basis of the levels presented in this publication. It distinguishes the following levels of education:
early childhood education (ISCED l=Level 0)
primary education (ISCED Level 1)
lower secondary education (ISCED Level 2)
upper secondary education (ISCED Level 3)
post-secondary non-tertiary education (ISCED Level 4)
short-cycle tertiary education (ISCED Level 5)
bachelor’s or equivalent (ISCED Level 6)
master’s or equivalent (ISCED Level 7)
doctoral or equivalent (ISCED Level 8).
Within early childhood education (ISCED Level 0), settings classified under ISCED-2011 have an intentional educational component and aim to develop cognitive, physical and socio-emotional skills necessary for participation in school and society. Programmes at this level are often differentiated by age, with early childhood educational development serving children under age 3 and pre-primary education serving children from age 3 until entry into primary school. Pre-primary settings in TALIS Starting Strong meet the ISCED-2011 definition for ISCED Level 02. Settings serving children under age 3 in TALIS Starting Strong were not required to meet the ISCED-2011 definition for ISCED Level 01.
Despite the distinction made by ISCED-2011 within ISCED Level 0, many countries, including several participating in TALIS Starting Strong, offer an integrated ECEC system (see Annex A of the first volume (OECD, 2019[1])). In integrated ECEC systems, a single government ministry or authority oversees ECEC programmes from birth or age 1 until entry into primary school. For countries with integrated ECEC systems that participated in data collection for both pre-primary settings and settings for children under age 3 (i.e. Denmark, Germany and Norway), the TALIS Starting Strong sampling strategy randomly split ECEC programmes that were expected to cover both age groups to be included in the sampling universe for one population of interest or the other. In this way, programmes could be sampled as part of the pre-primary sample or as part of the sample of settings for children under age 3, but the same programme would not be sampled for both levels of ECEC.
Next, staff were sampled within these settings if they were serving children within the designated level of ECEC (see Annex A). As a result, the sample of pre-primary staff and leaders is representative of staff and leaders in settings providing pre-primary education across all nine participating countries, regardless of whether an integrated system exists or not. Similarly, the sample of staff and leaders in settings for children under age 3 is representative of staff and leaders in settings providing services for this age group across all four participating countries, regardless of whether an integrated system exists or not. Home-based settings were included in the samples of settings for children under age 3 in Denmark, Germany and Israel. However, to enhance comparability with pre-primary education settings, data from staff in home-based settings are excluded from this report. These exclusions represent 16% of the sample of settings serving children under age 3 in Denmark, 16% in Germany and 60% in Israel.
The report uses the phrase “both levels of education” as shorthand to refer to pre-primary settings and settings for children under age 3 simultaneously, when referring to results for countries that surveyed staff and leaders in both pre-primary settings and in centres for children under age 3. Readers should bear in mind that the age distinctions in levels of ECEC do not necessarily reflect the organisation of the ECEC system or ECEC programmes in all participating countries (see Annex A of the first volume (OECD, 2019[1])). Furthermore, programmes included in the samples for both levels of ECEC may also serve younger or older children.
The report uses the term “centres” as shorthand to describe all ECEC settings. The specific programmes or settings vary across and within countries (see Box 1 for details on the types of settings covered in each participating country).
