Learning assessment is essential for education systems to provide quality and equitable education. Education partners, both national and international, are supporting education systems around the world in their efforts to develop and implement holistic learning assessment strategies and mechanisms. In many cases, examining how learning is being measured and multi-stakeholder cooperation led to transformative changes in curriculum and skills development at the national level. These partnerships and collaborations for measuring learning rely on the principles of Education Diplomacy to agree upon and work toward their goals.
