The proposed knowledge and support technical assistance (TA) will conduct a diagnostic of what works in education technology (EdTech) in Cambodia, Indonesia, the Philippines, and Viet Nam. It will identify at what level technology solutions can be used based on ‘EdTech Readiness’ of countries, and pilot EdTech interventions accordingly. The TA builds on an ongoing regional TA on innovation in education sector development, which also focuses on Cambodia, Indonesia, the Philippines, and Viet Nam. The ongoing regional TA assessed the impact of the fourth industrial revolution (4IR) on labor markets by examining two economically important sectors in each country. The proposed TA builds on one of the key lessons from the ongoing regional TA: the need to leverage technology to provide trainings and skills development.
