Toilet training is needed by children to control urination and defecation. The failure of toilet training can be caused by inaccuracy teaching children. The techniques used in conducting toilet training are oral technique and modelling technique. This research was to examine the effectiveness of oral technique and modelling technique for a successfull toilet training for toddler. This study used quasi experiment with two group pre and post test static design. The total sample of 30 toddler at Desa Pamijen Kecamatan Baturraden were invited into the study and were divided into two group . The hypotheses was tested by paired t-test. Results showed age range from 2,1 to 2,6 years old. The parent education was mostly senior high school (40%). The oral technique achievement was 33,33% , while the modelling was 80%. There is a siignificant difference between the effectiveness of oral technique and modelling technique for successfull toilet training as indicated by the disparity between increasing score average of two technigues. The increasing toileting ability average (0,4933) and t=14,929 (p=0,000) the modelling technique is bigger than the increasing toileting ability average (0,2000) and t=3,873 (p=0,002) oral technique. It concludes that modelling technique is more effective than oral technique for the successfull toilet training for toddler.
