This study was concerned with the problem of decreasing 4-H members at the junior high level. Data were collected from 289 seventh, eighth, and ninth graders in interviews. Data were classified into two groups according to the level of participation in 14 4-H events and activities; there were 173 high participators and 116 low participators. The purpose was to determine the relationship between level of participation and personal characteristics, leisure time activities, attitudes, and family characteristics. Major findings included: (1) level of participation was significantly related to sex--girls had higher participation than boys; (2) participation was higher among those who were active in several clubs; (3) participation was greater among children who joined 4-H at an earlier age and school grade; (4) a higher participation level was achieved by those with definite plans to attend college; (5) participation was higher among those who received visits from extension agents; (6) participation was higher among those who spent the most time listening to the radio; (7) participation was greater among those whose mothers worked outside the home; (8) participation level was significantly related to father's and mother's education; and (9) high participators were more likely to be nonfarm residents.
