The paper is focused on the results of the first conducted sectoral interim evaluation in Croatia, that of the Croatian Tourism Development Strategy till 2020. The authors reflect on the methodology used, the applied approach, the objectives and scope of the recently implemented interim evaluation of the mentioned Strategy. They comment on the purpose and functions of this sectoral evaluation and observe objectively its role from the point of view of achieving effectiveness, long term, and concrete and sustainable development impacts in the sector of tourism. The main findings of the conducted evaluation are presented, based on a number of held interviews and a survey with the main policy makers, civil servants as well as all key stakeholders in the tourism industry. Particular focus is given to evaluation questions and judgement criteria based on the evaluation criteria of effectiveness, impact and sustainability. The authors indicate some of the positive achievements, and particularly the current problems and challenges in the segment of tourism in Croatia in the period until 2020 and beyond. Along with observations related to the issues of accountability in the sector, the paper also provides reflections on the learning effects as the end result of such an evaluation, contributing to further policy development and policy learning in the sector of tourism. The authors indicate that their experience with this first interim evaluation could serve as a good practice example for conducting similar sectoral evaluations in Croatia as well as a tool for further long term development of tourism in the country, since the sector is of pivotal importance for Croatia’s local, regional and urban development as well as its overall economic competitiveness. Particular attention is given to some of the noted deficiencies and needs for further improvements in this sector, vital for Croatia’s further development. Recommendations are provided for improvements of the overall Croatian tourism development policy, with specific focus on the effectiveness of the so far achieved results as well as sustainable implementation of the Strategy and overall policy, aiming at reaching major and more concrete development impacts in the field of tourism.
