Previous research indicates that gender mainstreaming is difficult to apply. Obstacles such as lack of political will, cultural and institutional resistance, lack of understanding, clashing perspectives and priorities, as well as insufficient resources, are most often cited as the cause. This study, against the background that these obstacles are founded in institutional contexts, intends to use feminist institutionalism to analyze state authorities' ideas about gender mainstreaming through the analysis of values, descriptions, and prescriptions. The results show that analyzed authorities are consistent in their basic ideas and values, where the strategy is taken seriously and seen as important. The annual reports are prepared in an operational manner, which shows action and progress. The result indicates that there is a general lack of prescriptions.
