The article highlights the necessity of self-assessing the development level of their general and special competencies by future specialists in special and inclusive education. It emphasizes that self-assessment is a crucial element of self-development and successful learning as it enables students to better understand themselves and their progress. The authors note that regular self-assessment allows individuals to recognize their strengths and weaknesses in the learning process; set goals and action plans to achieve educational or professional success; analyze the effectiveness of implementing methods and techniques in their own activities; ensure personal growth and the attainment of ideals. The article provides summaries of both initial and subsequent students’ self-assessments. The findings from the initial measurement concluded that students faced the greatest difficulties with general competencies, particularly in communication in a foreign language, decision-making, and conducting research at an appropriate level. Among the special competencies, the ability to develop and implement innovative methodologies and technologies for correctional and developmental work with individuals with special educational needs was highlighted. The generalized analysis revealed that the majority of students rated themselves at an intermediate level. To enhance the development of competencies and foster a positive attitude towards their own achievements, interactive methods such as role-playing games, discussions, debates, case studies, etc., were applied, and a series of webinars were introduced into the educational process. The analysis of the subsequent self-assessment indicated an improvement in the development of both general and professional competencies, demonstrating the effectiveness of the proposed methods and approaches.
