next 20 institutions fell from 20 to 18 percent, 

 whereas the proportion in other institutions 

 rose from 37 to 4° percent. 



Shifts in the same direction occurred for first- 

 year, full-time graduate enrollment. By l'^70-71, 

 the proportion of such students in the first 20 

 institutions declined to 29 percent, from a high 

 of 37 percent in 1962-63. The share of such 

 enrollments in the second 20 institutions re- 

 mained almost constant at about 17 percent, in 

 contrast to the proportion in all other institu- 

 tions which climbed to 54 percent, up from 45 

 percent in 19c.2-ci3. 



This dispersion of graduate education during 

 the last decade is of course a continuation of a 

 long-run trend created by the increase in institu- 

 tions involved in this level of education in sci- 

 ence and engineering. 



Private and Public 



Institutions in Graduate Education 



The responsibility for graduate training of 

 scientists and engineers is shared by private and 

 public instituticms. Despite their smaller 

 number, private institutions have exerted much 

 influence in shaping and enhancing graduate 

 education as a whole. 



The number of public institutions granting 

 the doctoral degree in the sciences and engi- 

 neering increased somewhat more rapidly than 

 that of private institutions over the 1963-71 

 period, as indicated in figure 57. In each of these 

 years an average of five public and three private 

 institutions awarded the doctoral degree for the 

 first time. As a result, the number of public 

 institutions awarding the doctoral degree ex- 

 ceeded private institutions by 41 in 1971, as com- 

 pared with 24 in 1963. 



While differences in the number of institu- 

 tions of each type changed only moderately, 

 doctoral graduates from public institutions in- 

 creased more rapidly (figure 57). As a conse- 

 quence, the prciportion of graduates from public 

 institutions rose from 59 to 66 percent during 

 the period and those from private institutions 

 declined correspondingly from 41 to 34 percent. 



When the level of recent graduate enroll- 

 ments are considered, the diminishing role of 

 private institutions is even more apparent 

 (figure 58). Enrollments in private institutions 

 peaked in 1969 and declined by 5 percent in 1970, 

 while graduate enrollments in public institu-
