A parent-teacher partnership is a collaborative relationship between two key participants in a child's education. This partnership involves sharing information, working together to set goals, and regular communication to support the child's academic and personal development. In this partnership, both parents and teachers should play an active role in providing support in the child's education. Parents can support their child's learning by creating a positive home environment, setting expectations and goals for their child's academic success, and communicating with teachers about their child's progress and problems. Teachers, on the other hand, can support a child's learning by providing high-quality instruction, creating a safe and comfortable classroom environment, and communicating regularly with parents about the child's progress and improvement. The goal of the research was to investigate the perception of cooperation among teachers and parents, whether there are gender differences in the evaluation of cooperation, whether there is a link between the evaluations of teachers and parents and their attitude about the quality of cooperation in relation to personality traits. The data was collected in schools, and the questionnaire was distributed in paper form. The results showed that parents and teachers see communication as satisfactory, the attitude towards cooperation is positive in both groups, while they rate the level of parental involvement as low. There is no difference in parental assessments of cooperation between fathers and mothers. Furthermore, the results show that teachers with a better attitude towards cooperation are more open to involving parents, but parents with a more positive attitude are also more willing to be involved. Finally, the personality traits of emotional stability, extraversion and conscientiousness show a connection with the attitude towards cooperation and the quality of communication among teachers, while pleasantness shows a connection with the quality of communication, conscientiousness with parental involvement, and pleasantness, conscientiousness and intellect with the attitude towards cooperation among parents. Ultimately, a parent-teacher partnership is key to a nurturing environment in which a child will reach their potential. By working together, parents and teachers can help ensure that children receive the best possible education and support for their growth and development.
