Finnncinl Support. The availability of financial 

 support may influence the number of graduate 

 students entering the sciences and engineering, 

 although the measurement of such direct effects 

 may be confounded by university efforts to 

 provide support for students in all fields of grad- 

 uate study. Moreover, there are certainly other 

 motivational factors affecting the choice of field 

 for graduate education. 



The sources of graduate support for major 

 fields of science and for engineering are shown 

 in figures 42 and 43. The largest percentage of 

 students supported by fellowships, trainee- 

 ships, and assistantships is in the physical 

 sciences, and the smallest in the social sciences. 

 The number of science and engineering students 

 supported by the Federal Government declined 

 by 15 percent between 1969-71 whereas those 

 depending on self-support increased by 19 per- 

 cent (from a lower base).

 bachelor's and first professional degrees in the 

 sciences and engineering are shown in figure 44
