The measurements of height and weight in the Stockholm school health service was appraised in relation to the screening value, the costs and benefits. The concept of a doubtful screening value of growth surveillances at school age was supported. Investment costs and running expenses were very low. The measurement procedure used only 2% of the total time spent by the nurses in the school health service. The growth data were an appropriate prerequisite for the reassurance of adolescents about their developing identity and body image. The growth data also constituted an appropriate indicator for public heath research. The benefits and low costs may justify maintenance of the measurements in the school health service despite a low screening value.
