Objective: The scoping review outlined in this protocol aims to identify the key characteristics and types of available evidence in the area of implementation and measurement of Internationalisation at Home (IaH)/Internationalisation of the Curriculum (IoC) in Higher Education (HE) since 1999.

Introduction: IaH/IoC has received increased attention during the last past few years, but despite that, many Higher Education Institutions (HEIs) find it challenging to implement it. The IaH/IoC indicators are often not included in the HEIs’ monitoring/evaluating strategy, which complicates the assessment of the effectiveness of such an implementation.

Inclusion criteria: Peer-reviewed or grey literature published in English or Swedish, from 1999 or after, and describing the implementation and/or measurement of IaH/IoC. Articles focusing on individual aspects of curricula will be excluded, as well as articles focused on educational settings other than higher education.

Methods: The JBI methodology will be combined with the PRISMA Extension for Scoping Reviews checklist, PRISMA-ScR (Tricco et al., 2018) to guide the execution of this scoping review. Literature searches will be performed based on the main concepts of the review. The following databases/platforms will be searched: Scopus (Elsevier), Web of Science Core Collection (SCI-EXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, ES), ERIC (ProQuest), Education Database (ProQuest), APA PsycInfo (ProQuest). A grey literature search plan following the Godin et al. (2015) search strategies will be implemented. Data extraction will be executed based on a pre-determined framework, and data will be analysed using both quantitative and qualitative methods.
