The main goal of this research was to describe the type and level of parents’ concerns about child development and behaviour according to the PEDS® test (Parents’ Evaluation of Developmental Status). The sample included 289 parents of children from three to seven years of age, from two preschool institutions in Serbia. A significantly high correlation was determined between parents’ general concerns and expressed concerns with regard to behaviour (χ2 = 17.86, df = 2, p < .001) and getting along with others (χ2 = 22.57, df = 2, p < .000). A marginally significant correlation was determined between parents’ general concerns and manifested concerns with regard to fine motor skills (χ2 = 5.90, df = 2, p = .052), as well as expressive language (χ2 = 5.858, df = 2, p = .053). According to the criteria of PEDS® test, this research identified 56.4% of children whose development needed to be monitored, 27.7% of children who needed to be referred for detailed diagnostic procedures, and 1.7% who needed to be included in treatment or special education support.
