Most of the indicators presented in the OECD's annual publication, Education at a Glance are based on detailed information provided through the "UOE" (UNESCO, OECD and Eurostat) data collection. The UOE data collection consists of a series of detailed questionnaires and data tables covering education expenditure, enrolments, entrants, personnel and graduates and is completed by all OECD countries on an annual basis. My Department is responsible for completing and submitting the Irish questionnaires. This data required is sourced from both within the Department and from external bodies such as FETAC, the HEA and FAS. Some indicators are based on other sources such as the OECD-INES Network for the Collection and Adjudication of System-level descriptive Information on Educational Structures, Policies and Practices (NESLI) and the OECD-INES Network on Labour Market, Economic and Social Outcomes of Learning (LSO) which are also provided by my Department. Other indicators are based on the Labour Force Survey (the Quarterly National Household Survey in the case of Ireland) and the EU-Survey on Income and Living Conditions both of which are provided to the OECD both directly by the Central Statistics Office and via Eurostat.
