School docimology is a scientific branch that deals with the terms of monitoring, assessment, grading and the product of these processes – grade. Grade is a means of monitoring pupil’s progress and knowledge, not something that a student must have better despite poorer results. If the parents are not satisfied with the grade, they ask the teacher for explanation. Which is an indicator that the grade is more important than knowledge. The parents influence on the teacher due to the grade is larger when the grade is lower. Also, this can lead to a conflict between parents and teachers. In order to avoid the conflict, teachers are obligated to acquaint parents with the Pravilnik o načinima, postupcima i elementima vrednovanja učenika u osnovnoj i srednjoj školi. As well as cooperate with each other. Since they have the same interest – wellbeing of the child, teachers and parents should be on the same side. Furthermore, the results of the research showed that despite the fact that parents are familiar with the Pravilnik the parents influence on the teacher due to the grade is still present.
