In September 2017 UM (Medical University of Lodz) began the implementation of the project 2017-1-PL-KA107-036411. This project is a continuation of the 2016-1-PL-KA107-024824 project carried out last year with the University of Novi Sad in Serbia. The rules for exchanging students and employees of UM and UNS were created on the basis of many years of experience and the rules implemented in the Erasmus + Ka107 project for 2016. The 2017 project has been fully implemented and all mobility completed and recognized. The activities included the exchange of students and employees between the Medical University and the Medical Faculty at UNS (University of Novi Sad, Serbia). The project was coordinated by the University Coordinator of the Erasmus + Program and the Department of Foreign Cooperation of the Medical University. The implementation was in line with the university's European policy for 2015-2020, the main element of which is broadly understood internationalization. The employees of the International Cooperation Office and the Pro-Dean for International Cooperation and Foreign Students of the UNS had a key impact on the shape and manner of the project implementation by the partner. The project is a continuation of the cooperation between the two institutions initiated in the Campus Europea project and continued in the Erasmus + KA107 project.Due to the receipt of financing in the amount of 62,050 Euro, we completed the exchange of 11 students from the fields of medicine and dentistry and 12 employees.Participation in the program supported and developed the process of close cooperation between the institutions. The number of students and employees interested in mobility has once again significantly exceeded our expectations. The quantitative goals of the project were exceed. Within the financial agreement, we received funds for 10 people - study trips. Our curricula (medicine, dentistry) are compatible and both the universities run classes in English, therefore the cooperation between the universities was very good. The universities signed an interinstitutional agreement for the exchange of students and employees of both the universities for the years 2016-2021 signed by the UNS Academic Coordinator and Rector's Proxy for International Exchange.The main quality objectives of the project were: development of professional, linguistic and cultural competences of students and employees of both universities; support for the internationalization process of the UM and UNS; developing cultural awareness, tolerance and the ability to function in a multicultural environment.The students of both universities emphasized that the participation in the program taught them tolerance, recognizing the value of other cultures, cooperation with people from other environments and cultures, increased their interest in European affairs and world events. It also taught them planning, organization, independence and faith in their own skills. Competences acquired by the project participants indicate its success. Employees put the greatest emphasis on acquired practical knowledge, language skills and strengthening of the cooperation between the universities.Participants' reports indicate 92.86% satisfaction with mobility for students and 100% satisfaction with employees. The result underlines the importance of international cooperation for both the universities and the impact Erasmus has on mobility development with partner countries. Student recruitment was in accordance with the principles of the Erasmus + program. The students completed a minimum of the first year of study. Their average, grade from a language and additional academic activity were taken into account. The best received from the Erasmus Program Commission a place in the program and funding in line with the rates in force in the Erasmus + program mobility with partner countries in the 2017 competition. All the students were treated equally.Employee mobility was very popular. Places, as before, were allocated at the Medical University based on the order of applications, but priority was given to the units that accepted employees in Serbia in the previous project. Our goal was to strengthen the relationship between similar units. In case of UNS, scientific achievements were also analyzed. The Erasmus KA107 cooperation project has contributed to the personal and academic development of students and employees of both universities. The main goal of universities today is to be open to changes and social multiculturalism. The implementation of the KA107 project mobility is a model example of the development of cooperation between European universities from the first contacts under Campus Europea in 2015, to the exchange under the KA107 2016/2017 Program and its continuation in the KA107 2017/2018 and 2018/2019 projects contributing to the significant internationalization of both the universities and their regions.
