Positioning school leaders as important enablers of foundational learning improvement

Indonesia is home to over 3 million teachers and 50 million students, spread across 270,000 schools. While national efforts to improve foundational learning are underway, challenges persist around teacher support, equitable access, and school-level leadership.
​
In this context, GSL has partnered with INSPIRASI Foundation since 2018 to enhance the impact of school leaders in schools.
Our Work with INSPIRASI
INSPIRASI (Educational Leadership Initiative for Achievement) is an Indonesian nonprofit that aims to improve the quality of student learning through strengthening school leaders’ effectiveness in schools across the country. ​
​
Our collaboration began in response to the global COVID-19 crisis, but has since expanded into a long-term effort to build resilient, future-ready school leadership.

Supporting learning recovery through school leadership
In the aftermath of COVID-19, many schools faced learning losses from lost instructional time due to school closures, remote instruction, and slow re-enrollment in school. In collaboration with GSL, Inspirasi developed a training program for teachers and school leaders to address some of these challenges. Through the program, participants learned how to assess students’ basic numeracy skills, conduct differentiated foundational instruction based on the student’s assessed level, regularly check for understanding, and, in some cases, implement individual tutoring.

Program Akselerasi: Strengthening foundational learning at scale
In 2023, we partnered with INSPIRASI to implement a randomized controlled trial, Program Akselerasi, to assess the impact of school leadership training on advancing differentiating teaching strategies to improve foundational numeracy outcomes. The program covered 300 schools across two districts and included three arms: teacher training only, teacher training plus school principal coaching, and a control group.
​
The findings, available in late 2025, will contribute to the growing evidence base on how school leadership can accelerate and sustain learning improvements at scale.
