The aim of the present study was to investigate the expectations and evaluations of Estonian school principals on the work of school psychologists. Surveys have shown that teachers and school principals value traditional assessment activities but also desire more consultation. School psychologists emphasize the importance of system counseling, but in practice it can seldom be seen. One of the obstacles to the change of school psychologists' roles might be the expectations of school principals. Therefore, school principals were questioned regarding these issues. One hundred and seven principals participated in the study. In addition, interviews were carried out with three school principals. The results showed that the most desired services by Estonian school principals are individual counseling of children and consultation with teachers and parents. System counseling is expected less frequently, but no strong resistance to it was found. It seems that school principals do not desire it because they are not yet aware of its possibilities.
