The present study aimed at assessing Hong Kong young children's gains in creativity and their teachers' application of arts education after a one-year artists-teachers collaborative arts education project that involves various art forms (i.e. drama, visual arts and integrated). Participants included 790 young children, 217 parents and 65 teachers in seven kindergartens and nurseries. Measures included the Test for Creative Thinking-Drawing Production, Story-Telling Test (STT), the subscales of parent-rated creativity, communication and motivational characteristics, and the adapted Scale of Application of Arts in the Classroom. Among the three art forms, children in the visual arts group demonstrated highest gains in verbal creativity as evaluated by the STT. Based on parents' report, there were significant differences in children's communication characteristics across the three art forms. Significant differences across art forms were also found in teachers' confidence in teaching arts to 3-4?years old and their perception of arts for arts sake. Both teachers and students take advantage of the professional and artistic input and guidance of practising artists in arts appreciation and production. Implications and limitations were discussed.
