Ability assessment and job structure measures in occupational mobility
Recent and petential changes in tech.nology· have resulted in the
anticipation of increases' in the frequency of job changes. This has
led manpower policy makers to investigate the feasibility of
incorporating the employment skills of job groups in the general
prediction of future job learning and performance with a view to the
establishment of "job families" within which transfer might be
considered reciprocally high.
A structured job analysis instrument (the position Analysis
Questionnaire) is evaluated in terms of two distinct sets of scores;
job dimensions and synthetically established attribute/trait
Studies demonstrate that estimates of a job's structure/dimensions
and requisite human attributes can be reliably established. Three
alternative techniques of statistically assembling profiles of the
requisite human attributes for jobs are found to have differential
levels of reliability and differential degrees of validity in thei r
estimation of the "actual" ability requirements of jobs.
The utility of these two sets of job descriptors to serve as
representations of the cognitive structure similarity of job groups
is investigated in a study w'!:W!m:ir,d'hsimulates a job transfer situation.
The central role of the index of similarity used to assess th~
relationship between "target" and "present" job is demonstrated. The
relative extents to which job structure similarity and job attribute
similari ty are associated with positive transfer are investigated.
The studies demonstrate that the dimensions of jobs, and more
fruitfully their requisite human attributes can serve as bases to
predict job transfer learning and performance. The nature of the
index of similarity used to optimally formulate predictions of
transfer is such that networks of jobs might be establishable to
which current job incumbents could be expected to transfer
positively. The derivation of "job families" with anticipated
reciprocal transfer consequences is considered to be less
