The goal was to examine factor struc ture of 8 BRIEF scales: inhibit, shift , emotional control, initiate, working memory, organization of materials, plan/organize and monitor. Teachers were not considered to be participants, but only supporters of its implementation. The study confi rmed original two factor structure of the BRIEF with 80.6 % of total variance explained. It has shown that BRIEF is feasible and reliable in application with this population and it can be used for school assessment as a basis for educational planning and development of executive functions.
