V. CONCLUSIONS
- -
Work completed and underway at AFHRL is providing the Air Force
with 0,JT cost estimates compatible for comparison with TTS cost estimates.
This is a valuable first step hut these cost data have limited use
by lhcn~selves. They must be used in conjunction with measures of
other criteria.
Quality of training received is one of the criteria not incorporated
into the cost estimates. Individual performances on Specialty Knowledge
Tests were used in this paper to compare the quality of OJT and TTS
graduates for a limited number of specialties. The differences in SKT
scores found using analysis of covariance, were too small to allow
rejcctiorl of the research hypothesis that OJT and TTS graduates are
of cclual quality. There is clearly no alarming difference in quaJit$
as measured 11s SKT scores for the specialties analyzed. One may
not generalize either the cost results on the SKT results to other
ZiEcinltics.
Future work concerning OJT/TTS tradeoffs should include improved
OJT cost estimation, repetitions of the SKT analyses of this paper for
other specialties, development of a computerized algorithm for assigning
non-prior service persomel to OJT and Technical Training Schools, and
dcvelopnlent of metliodologier. for determining the capacity of units to
conduct OJT. This last item deserves special emphasis because it is
the key to efficient utilization of !Air Force training resources.
AN Force operational units have manpower standards against
which OJT trainees are drawn. Each additional trainee replaces’ a
more qualificcl individual and requires the time of other personnel
to conduct 0,J’l’. Assignment of an excessive number of trainees
