While in some countries, comparative education is fully established as a distinct field of educational research, in others it might best be regarded as an interdisciplinary field that brings together scholars from diverse specializations. For instance, specialists in math education,[4] social studies education,[5] or various arts subjects may develop research designed to enable meaningful comparisons between national educational systems with a focus on their specific subject area of expertise. It follows that comparative education research can examine schooling holistically and globally (macro-level analysis), or may alternatively focus on the status of a particular subject area in a specific region of the world, thereby benefiting from subject-area or regional expertise (meso- or micro-level analysis).
