"In the academic years 2018-2021, the University of Bialystok (UwB) implemented the fourth, Erasmus+ KA107 project with the following partner universities: a) Kosovo: University of Prishtina ""Hasan Prishtina""; b) Ukraine: ""Lviv Polytechnic"" National University, Taras Shevchenko National University of Kyiv; Odessa I.I. Mechnikov National University; c) Russian Federation: Smolensk State University, Immanuel Kant Baltic University (Kaliningrad); d) Belarus: Yanka Kupala State University of Grodno, Baranovichi State University, Belarusian State University; e) Armenia: Yerevan State University; f) Canada: University of Quebec Montreal (UQAM); g) Serbia: University of Belgrade; h) Thailand: Silpakorn University; i) United States: Michigan State University, Indiana University - Purdue University of Indianapolis; i) Georgia: Ivane Javakhishvili Tbilisi State University; j) Vietnam: Nong Lam University, Vietnam National University - University of Science Ho Chi Minh City (VNUHCM). The project concerned SMS, STT and STAmobilities. The implementation of the Erasmus+ programme, despite the occurrence of the Covid-19 pandemic, was successful, both in terms of compliance with the ECHE Charter, the Erasmus Policy Statement (EPS), the UwB Development Strategy 2014-2024 and the development strategies of the partner universities. According to UwB's assessment, the planned qualitative and quantitative objectives were achieved to a large extent. UwB and partner universities ensured equal access to the programme, treatment, and recognition of mobility for all participants. All information concerning project implementation was made available on the UwB website, on the websites of individual departments/institutes and on the websites of partner universities. Participants were provided with support from UwB and partner universities before, during and after mobility. Mobility of mixed character was implemented for the first time. The universities have managed to implement objectives included in the development strategy, . e.g: developing cooperation with foreign partners, improving qualifications of the academic staff (also in terms of foreign language skills and establishing contacts abroad, participation in international projects), development of students through participation in international exchanges. The length of stay at UwB per student from partner countries was over 4 months. In the course of the project, women more often carried out mobility. In the case of students it was 60% of all participants, and - employees - 60.87%. This is due to women showing more activity, striving to broaden their horizons to be more competitive in the labour market, quite dominated by men. For studies, In the academic years 2018-2020, 4 students came to UwB to pursue a study program at the Faculty of Law (from Kaliningrad, Pristina, Tbilisi, Yerevan). For the first time under KA107 project it was possible to realize SMS mobility (student from the Faculty of Physics) to Indianapolis (USA). UwB and partner universities supported reintegration of returning programme participants and enabled them to share experiences gained with other students/staff. As far as project results and impact are concerned, it should be noted that students' and staff's mobility had a very positive impact on their self -development, competence development, and professional careers. Erasmus+ KA107 programme implemented by UwB and partner universities had a positive impact on local and regional communities. The incoming students, carrying out mobility at UwB, took part in a number of initiatives, which brought long-term benefits to various community stakeholders. Participation in the programme contributed to increasing the importance of UwB and partner universities in the international arena and developing cooperation at the European/international level. High indicators of satisfaction of the mobility participants testify to the good quality of the implemented project, which had a direct impact on the continuation of the cooperation within Erasmus+ KA107 and resulting in obtaining funding from projects within the KA107 calls 2019-2021 and 2020-2022. The partner universities participating in the project will actively increase the number of mobilities and will strive to implement mobility in physical, virtual or mixed form as efficiently as possible. UwB and partner universities will continue to maintain high standards in accordance with the European Commission requirements and introduce new solutions, which will allow the project to function and its continuation."
