In the context of physical and health education (PHE), CROFIT tests allow monitoring students' morphological characteristics, as well as their motor and functional abilities, which serve to assess their status and development and to create appropriate teaching plans and programs. Although the results of these tests can be influenced by numerous genetic and environmental factors, this thesis will focus on the impact of gender, age, and neuro-risk factors. Neuro-risk factors can be defined as external and internal factors that affect a child's development during the prenatal, perinatal, and postnatal periods. It is important to emphasize that neuro-risk factors do not always result in developmental difficulties and that brain neuroplasticity, along with early interventions, can significantly contribute to the optimal development of a child. The research was conducted on students from various parts of Croatia, using a questionnaire that included questions about pregnancy, childbirth, and postnatal development. Additionally, two tests were used to measure motor abilities: the trunk lift test and the trunk forward bend test. The results did not show significant differences in performance between boys and girls, nor between children with and without neuro-risk factors. However, significant differences were observed concerning the age of the participants. When analyzing the results, it should be considered that neuro-risk factors do not always lead to developmental and motor skill difficulties and that the study included children from regular schools without developmental challenges.
