one the number of girls. Figure 2 represents the same facts 

 for the other group of school systems. In Figure 3 the 

 ''totals'' for the two groups are shown. The left line is for 

 the systems having semiannual promotion. The right line is 

 for the other group of school systems. 



Sex Differences, The sex aiiTerences for the systems 

 having semiannual promotion (Figure 2) are slight. There 

 is an indication that the girls stay in school a little better 

 than the boys. In Figure 1, which is for the other group of 

 school systems, this condition is more pronounced.

Group Differences. Figure 3 is the most significant. It 

 it clear that above the age of eleven the school systems having 

 annual promotion have relatively more children in school. 

 This probably means that they are holding the children bet- 

 ter, altho we cannot be certain because of the influencing 

 factors mentioned above, particularly that of nonresident 

 attendance. 



One should not conclude that this difference is due to the 

 difference in the organization of the two groups of school 

 systems, since a number of other factors enter into the situ-
