The paper topic is focused on the process of professional identity formation of students from different fields of social sciences such as social pedagogy, social work, law, psychology, sociology, bussiness and public management.The research is being realized in Lithuania. This research is a part of the PhD thesis and it is grounded on the lack of the knowledge both in national and international contexts. Recent analysis of the results of other scientists (e.g., Žydži?nait?, Saul?nien?, 2006; Žydži?nait?, 2005; Urbonien?, 2004; Adamonien?, 1999; Petrauskait?, 1996; Boreham, Gray, 2005; Proweller, Mitchener, 2004; Branch, 2000; O'Neill, 1999; Ryynanen, 2001; Olesen, 2001; Kwakman, Schilder, 2004; Franzak, 2002; Sundin, 2001; Jeans, Forth, 1995, etc.) indicated the existence of various factors that make an influence on professional identity formation. Factors such as: professional knowledge, acknowledgement with meaning and use of studies, studies of theory, effective educational training structure and process that is focused on one's personal development, training in practice, professional development curriculum and/ or courses, development of research competencies, intellectual and physical instruments for information search, work experience and experience that is gained during practise at university, student's life experience, teacher experience, competence and authority, social interaction and communication and their acknowledgments with colleagues and with students, different personal characteristics (devotion to profession, feeling oneself a member of professional community, autonomy, etc.), particular characteristics (altruism, orientation to a client, disposition to help, etc.), calling, personal and professional development and even age of student are the ones that constitute the formation of the professional identity in studies. Analysis of scientific literature highlighted that professional identity formation in higher education is an inconstant longitudinal complex process that reveals at two levels: both structural and personal (level of personal attitudes and/ or characteristics), has several significant beginnings (one of them starts with entering university), directions (e.g. to oneself, to organization and to permanent development and lifelong learning) and stages (role-identity pre-socialization, discovery, construction, maintenance and disposition). It lasts as long as person identifies oneself with professional field, but can not be separated from formation of other personal identities as well as from the influence of other significant internal and external factors. Identity and its formation process are being influenced by various structural, personal and organizational factors. Unity of theory and practise, level of personal knowledge and its significance towards profession, dynamic and auspicious structure of studies, that embraces not only information, but also practical, supporting in all meanings and individual-orientated educational environment, ability to evaluate one's suitability to a study field are the essential prerequisites to professional identity formation. But it is still not so much verified and for this reason questions such as later mentioned have arised: What structural elements of professional identity development in the bachelor studies of social sciences can be characterised as constant and permanent? What are possible levels of their expression? What are significant differences (if there any are) of the students' professional identity formation in the fields of higher education of social work, social pedagogy, law, management, psychology and sociology? These questions all together express the research question.The research objective is the process of students' professional identity formation in higher education of social sciences. The aim of this research is to highlight common and different aspects of the professional identity formation of students from different fields of social sciences in higher education.The phenomenographical research is based on the qualitative research methodology when an interview is being used as a data collection method and qualitative content analysis is being used as a data analysis method. Sample consists of thirty full-time 3rd and 4th year bachelor students from different fields of social sciences (sociology, social work and social pedagogy, psychology and law) in Lithuania.At the meantime the research is being performed, so expected final outcomes of it could be those: reseach highlights the differences of the students' professional identity formation according to the key elements of their studies field. The most significant aspects that influence formation of students' professional identity could be: 1) professional knowledge (and especially the one that is directly orientated to the students aknowledgment with a variety of directions and specializations inside the field and their internal differences), 2) professional values and 3) their coincidence with personal values. Other structural elements at the level of formal education as well as at the level of personal characteristics could be charaterized as second or lower level significance elements. One of the preliminary conclusions is being discovered at the meantime: in all fields of social sciences formation of professional identity occurs in two levels. First of all at the begining of their studies students evaluate coincidence of their personal characteristics with the values of the profession (and vice versa) and only afterwards they highlight the absence of the incompability in this area they reach second level of the process of professional identity formation where they are getting aknowledgement with variety of specializations inside profession and thus gaining understanding of differences both in knowledge and way of realising professional functions and thus developing their professional competencies. By the time I am sending this proposal the research is still being realized, so about more precisious conclusions and/ or findings I could inform later at the conference.1. Abbott, A. (1988).
