Internationalisation is one of the pressing issues for South-East Asian HEIs: Mission & Vision statements, as well as Strategic Plans confirm the strong will of the HEIs in the Region to strive for Internationalisation for the sake of students & graduates. Ministerial & Regional policy documents, too, advocate Internationalisation as priority for individual countries & the Region.What HEIs & policymakers lack are the core Recognition Mechanisms:- RM1 Regional Subject-Specific Qualifications & Assessment Reference Frameworks,- RM2 Measuring Full Volume of Student Workload as part of Programme Planning, &- RM3 Authentic Assessment of Programme Learning Outcomes.To address this gap, CALOHEA brings together 26 HEIs from 8 SEA Countries (Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Thailand & Vietnam), AUN-ACTS Network, AUN & 5 EU partners highly experienced in creating & helping HEIs adopt the 3 core RMs. University of Groningen & ASEAN University Network act as Project Coordinators &, together with all the Partners, will work to achieve the following:- create & install RM1-3 in 3 pilot areas – Civil Engineering (a door to the Engineering sector), Medicine (a door to the Health sector) & Teacher Education (a door to Social Sciences)- train Teams of Champions for Recognition & Internationalisation in 26 SEA HEIs- reach out to all ASEAN & many more SEA HEIs to encourage regional adoption of the 3 RMs &, thus, help any SEA HEI in Internationalisation efforts.Students & graduates will be direct beneficiaries, since RM1-3 will considerably facilitate mobility & employment. HEIs & their academic & administrative staff will be equipped with the tools to achieve higher level of Internationalisation. Policymakers, &the Region as a whole, will obtain the foundational tools and the Champions necessary to make a serious step forward in articulating a common HE Space and increase mobility among the SEA countries, as well as between SEA and other world regions
