This report presents main outcomes of a project on assessment of writing skills in early grades of primary school (EGWA), implemented by UNESCO in collaboration with Professor Juan E. Jiménez and his team from the Universidad de La Laguna in the Canary Islands, Spain, with the support of the Russian Federation. Findings of a literature review and a model EGWA instrument developed in the Spanish language, as well as an account of how this instrument had been developed and possible ways forward indicated, will be valuable for those who are concerned with a global learning crisis. While EGWA has the potential to enrich policy dialogue, this report is essentially intended for teachers, curriculum developers, assessment experts, and other types of practitioners, who are keen to improve their understandings of children’s writing skills and teaching and learning practice in early grades of primary education.
