The consistency between 3 to 5-year-old children’s choice of facial expression stickers and the choices made by nursery school teachers and parents in health evaluations over a 4.5.month period were evaluated at 21 nursery schools in Japan. Children at the nursery schools chose facial expression stickers at health checks conducted immediately after arríval at school a nd as they were leaving. For selected students, the teachers cond ucted health checks and chose a facíal expression stícker corresponding to their evaluation of the child’s condítion. At home, after the eveníng meal, the children and their parents conducted daily health checks, and each chose an appropriate facial expression sticker. Consistency rates and Cohen’s Kappa were calculated by age group for school arríval and departure, and total arrivalsl departures for all sampled children throughout the entire study period. There was moderate consistency between chíldren and teachers ímmediately after school arríval, but consístency was lower at school departure, except for 5.yearold children. Levels of consístency were higher at home than at school for every age group. Using facial expression stickers in health checks could be a useful method for 3. to 5.year.old children, who may find it difficult to express their physical condition verbally
