PHYSICAL DEFECTS AND SCHOOL PROGRESS 



In order to show more definitely in terms of school prog- 

 ress just what these handicaps mean we may apply them to the 

 cases of hypothetical non-defective and defective children. If 

 we assume that the average child without physical defects of any 

 kind will complete the eight grades in just eight years, how long 

 will it take defective children to complete eight grades? The 

 answer to this question may be found in Table 44 and the accom- 

 panying diagram.
