duty stations were extracted from the PDJc system for all FTB 3303 pereonnel
.
2.1.1 Studs PopulatiorA. The study hypclthesis required that the records of
personnel be reviewed for events or changes occurring over the course.of a
person’ 6 career in order to determine at what point in service spccializa-
tion on an equipment or gqoups of equipments took plac?. For the study,
this speciaiization or sub structure was of interest for personnel in sub-
marine crsws . These comprise the bulk of the NEC. because of th* continu-
ing evolution of equipment, training and measurement, some time limit
needed to applied to the data used so that analysis results would be rel-
evant . tiuilding on these general requirements three criteria were cstab-
1iShtd for selection of records for analysis. For each record s~lcct& ti
person h&d t0 have :
a . Graduated from “0” school after the proscribed start date.
b. Reported to the crew of an operating SSbN directly after “C’ school.
c . Taken four or mora SATs .
Review of data extracted indicated that few personnel in paygrade E-4 had
sufficient SAT records to be useful for analysis. Personnel in pbygrtide E-
6 had duty station histories which made a “cause-effect ” analysis of
school racords not very uscf ul . It. was tl-ieref ore determined to use a sur-
vey population of persons serving in paygrade E-5. Ninety-six persons in
paygradc E-5 met the criteria and all were used in the study. preliminary
analysis was done by randomly dividing the the population into two equal
groups to look for consistency of results. Thi study methGdology was also
applied to 16 persons in paygrade E-6 meeting similar critsria to ensure
thbt no discontinuities were introduced by limiting the population to piygrade
E-5.
