Candidate LLs joining LL associations and networks (ENoLL, Forum LLSA...) undergo quality- assessment processes based on specific criteria and evaluation frameworks to guarantee members meet their LL standards. Currently, limited attention is paid on how such evaluation methods can contribute to future LL-performance. The need to deeper understand the architectural aspects of LLs and further study effective management-approaches has been raised by other authors. Schuurman (2015) proposed a macro–meso-micro-level approach for classifying LLs. Despite its potential value, this three-level analysis approach has not yet been fully recognized in existing LL evaluation frameworks. The adoption of a harmonized macro-meso-micro evaluation approach, with a clear focus on the macro-level could support the development of LL towards sustainability, impact and efficacy. This paper aims to define a set of harmonized weighted criteria for a comprehensive LL evaluation framework to be used for assessing LLs on all three levels based on multi-method research approaches.
