The Higher Attestation Commission (VAK) is responsible for the promotion and career development of the Bulgarian scientists. There are two scientific degrees (Doctor and Doctor of Science) and two academic ranks (Associate Professor/Senior Research Fellow II Degree) and Professor/Senior Research Fellow I Degree). VAK’s activity is based on the “Classification of Scientific Areas and Topics” (1990). However this document does not take into account the new processes and changes in the world science. For instance the old pedagogical disciplines have recently amalgamated in a new science – the Science of Education with interdisciplinary, multidisciplinary and transdisciplinary character. Generally in the science, strong processes of subjects’ integration replaced the previous trends to subjects’ diversification. These new phenomena are not rendered in the Bulgarian Classification of Scientific Areas and Topics. Therefore, difficulties arise when attempting to shape in an adequate manner the new Bulgarian researchers community.
