The National Education Institute (NEI) is a key institution on national level striving to increase the quality of education on all levels of pre-university education with the aim to provide high quality and effective instruction for pupils and students. This can be realized through systematic, in-depth and professional cooperation and development of school practice in view of providing sustainability and continuity of impact and results. The project focused on the acquisition of new knowledge and skills and exchange of experience from three fields, which were according to the feed-back information received from study groups and taking into account key national and European guidelines in education, part of annual work plan of the NEI in 2014. They were considered as priority fields in planning the activities undertaken by advisers within area/subject groups: - assessment for learning - bringing research findings to teachers’ attention in a comprehensive way - career-long professional learning of teachers The main objectives of the project were: - professional and personal growth of advisers and increasing their competences, necessary for effective introduction of the assessment for learning elements in the pedagogic practice, including the use of appropriate tools - supporting teachers in selection, introduction and reflection about the research findings applied to the school practice - encouraging professional learning of teachers throughout their career from beginner to an experienced teacher. 23 educational advisers representing various subject groups (areas: humanities, science, languages, teaching at lower primary level, general area) took part in the 2-year mobility project. Their professional expertise includes subject and cross-curricular professional knowledge (didactic and methodical skills, key competences, ICT, professional development of teachers, sustainable development, research, publishing, communication in foreign languages). The core part of the project were two mobilities undertaken at the partner organisation Education Scotland (ES), which is the Scottish governmental executive agency, responsible for establishing policies at pre-school and school level and therefore comparable to the NEI in its role, mission and vision. Two 7-day visits provided the opportunity for the advisers to get more in-depth knowledge of 3 topics, exchange experience with the ES advisers and prepare the implementation plan into the Slovenian school practice. The programme included collegial learning at the ES, observation classes in primary and secondary school, visit to a higher education institution and participation at the Scottish learning festival, which is a major educational event bringing together Scottish schools and teachers. The other activities were language, cultural and pedagogical preparation of participants before mobility, internal and external dissemination and interim and final evaluation of the project. The project provided an impact at the local, regional, national and international level. The NEI is divided into 9 regional units, covering schools and kindergartens at all levels of pre-university education in Slovenia. The access to all schools and teachers is enabled through study groups, which are organized according to the regional key, thus ensuring equal opportunities to all target groups. By participating in the mobility the pedagogic advisers were committed to transfer the knowledge and experience to the school practice. At the national level the NEI is closely linked to the Ministry of Education, Science and Sport and its sectors. Through the activities carried out by the subject development groups (SDG), we influence modernisation, design and implementation of curricula and their documents and support schools to introduce changes. In agreement with all stakeholders, we will be able to introduce new knowledge and insights into the development of guidelines and recommendations for the school practice also in the future. In the partnership with the NEI, the ES also gained a critical view of its performance and solutions provided in the field of education. Both organizations are members of the international network CIDREE, the NEI is also a member of the ATEE. As such, the project provides an impact on the European and international area, as the majority of the EU members and non – European countries take active part in those initiatives. The outcomes of the project were introduced to broader professional public at national and international level on conferences (i.e. Effective Assessment for Learning, SIRIKT). Moreover, the impact of the project at the European level is evident through further cooperation with the Education Scotland and other organizations from 4 countries in the project "Student voice - THE BRIDGE to learning, which was approved this year in the programme Erasmus+, Strategic partnerships.
