In many cases, GEP implementation by different institutions has been conducted in isolation from others, and with processes that differ widely in terms of their scope and effectiveness, and in majority of cases without a proper assessment of gender equality needs and priorities, or the necessary monitoring and evaluation mechanisms. For example, to the degree that questionnaires for initial institutional assessment have been published by past gender equality projects such as GENDER-NET, EGERA, or INTEGER, these questionnaires vary substantially in length, topics treated, and measurements scales used. Results usually do not transcend the immediate project context while quality assessment of the reliability and validity of the generated data has not been conducted. While sensitivity to local (national, regional and organizational) context is key for a successful GEP implementation, a lack of more standardized assessment tools hinder mutual learning. Mutual learning, however is conditioned on the possibility to compare related gender equality measures with their resulting impacts in a meaningful and systematic way. ACT will provide an online, adaptable questionnaire framework that produces comparable data and thus facilitates knowledge sharing benchmarking and dialogue across national- and organizational contexts. The aim of the current document is to provide a catalog of potentially useful measurement scales for the ACT modular Gender Equality Audit and Monitoring tool. As such it provides an overview of interesting scales and their usage in the literature that should not be taken as a definitive list of which scales will be available in the final online tool.
