This paper focused on the acquisition rate of the Karen's weaving body technique and conducted analyses. Contents of analyses and their results are as follows:
(1) Mean values of acquisition rate of weaving body techniques by age cohorts (10-19, 20-29, 30 and over) were calculated. The result indicates that the acquisition order or time of weaving body techniques depends on the complexity and difficulty of each body technique. Namely, it implies that the acquisition time of body technique and age (developmental stage) might be highly related and the procedure of weaving should not affect the acquisition order.
(2) The correlation analyses between the acquisition rate and the age category (10-19, 20-29, 30 and over) were conducted. The result reveals that the level of Karen's weaving techniques develop as they get older
