The idea of UNESCO was largely developed by Rab Butler, the British Minister of Education, who had a great influence on its development.  At ECO/CONF, the UNESCO Constitution was introduced and signed by 37 countries and a preparatory commission was set up.  The Preparatory Commission worked between November 16, 1945 and November 4, 1946, the date on which the Constitution of UNESCO entered into force with the deposit of the twentieth ratification by a Member State.  In order to create the most comprehensive global education database, the UIS collaborates daily with national statistical institutes and specialized ministries around the world. The IUH assists countries in assessing their specific data needs for policy-making; identification of relevant data sources; assess the quality of existing data and map gaps; and developing national strategies for the development of education statistics. Since then, important reforms have been undertaken within the organization. The Internal Oversight Service (OIC) was established in 2001 to improve organizational performance by integrating lessons learned from programme evaluation into the overall reform process. In reality, the main tasks of the IOHI are rather auditing than supervising the program. It regularly conducts audits of UNESCO offices to examine compliance with management and procedures, but not the relevance and usefulness of the activities and projects implemented. – Education. The main objective is to achieve inclusive and equitable quality education and promote lifelong learning opportunities for all, to support countries in implementing the SDG 4-Education 2030 Agenda and to fulfil UNESCO`s mandate entrusted to it by the international community, to guide the coordination of the agenda and to make progress towards the achievement of the Sustainable Development Goal agreed at the level international in the field of education (4) and with a view to achieving the other SDGs.
