The Australian Government is supporting the Government of Timor-Leste in education through the Partnership for Human Development (PHD) and Apoiu Lideransa liuhosi Mentoria no Apredizajen (ALMA). ALMA supports the Ministry of Education, Youth and Sport (MoEYS) to develop teacher professional learning, particularly in support of its major reform of rolling out and implementing the National Basic Education Curriculum (new curriculum) across schools in Timor-Leste. Under the Teacher Development Multi-Year Study for Timor-Leste (the Study), the Education Analytics Service (EAS) is investigating how ALMA is making a difference to these teaching and learning outcomes. The new curriculum was developed in 2013 as a staged approach for pre-school to grade 6 with a focus on improving literacy and numeracy, as well as reducing student drop out. As presented in this Final Report, there are a number of findings that provide insight into the extent to which teaching practices and student learning outcomes are changing with ALMA’s support of school leaders and teachers and the implementation of the new curriculum. Results from the three years of data collection suggest that the ALMA program has been effective in strengthening elements of teaching quality, curriculum implementation and student learning outcomes.
