Personnel Assessment, Placement
Introduction
This unit focuses on selecting personnel and ensuring a good job-person match. It will
look at assessment and selection techniques, specific testing instruments, and the
requirements of a good test.
Personnel Assessment & Selection Techniques
Personnel assessment, selection, and placement became important during the First and
Second World Wars. A large number of recruits needed to be tested for suitability for
service and placement in military specialties. Techniques used and refined during these
two assessment efforts were adopted by industry and continue to be used today.
A variety of personnel selection techniques are available. Regardless of technique
used, they must meet two minimum requirements: scores generated by the test must be
reliable and the test must be valid. Reliability refers to consistency. There are several
methods to demonstrate reliability. One method is Test-Retest: if you take a test on
Monday and again on Friday, you expect the scores you receive will be fairly similar.
If they are, the scores are reliable. In addition to reliability of scores, tests must be
valid. A test is valid if it measures what it claims to measure. Like reliability, there are
several ways to demonstrate validity. One is Content Validity: if you took a class in
algebra and the final exam covered history, the test would not be valid because the
content of the test did not reflect the content of the material in the textbook or lectures.
Making a Good Job-Person Match
When an organization hires a new employee, it makes an investment; it takes time and
money to hire that individual. The organization has an expectation that it will receive a
return on its investment. If the person fits well in the position and remains with the
organization, a return on investment is realized; if not, there is a loss of investment.
Thus, it is important to establish a good job-person match.
A good match is accomplished by relying upon information from a job analysis. It
provides information on tasks to be performed and the knowledge, skills, abilities, and
personality characteristics (KSAPCs) required to successfully perform the job.
Assessment instruments which measure the required KSAPCs are then developed or
purchased to assist in matching the person to the job. To maintain professional and
legal standards, the instruments and methods must be reliable and valid, and they must
not discriminate unfairly. Ultimately, a good selection procedure should be fair to both
candidates and organizations. The candidates selected should be the best for the
positions being filled.
Employee Testing Tools
Personnel assessment includes methods such as biographical inventories; employment
applications; letters of reference; resumes and background checks; interviews; paper-
and-pencil tests of knowledge, skills, abilities, or personality characteristics; as well as
honesty and performance tests. Assessment centers typically combine most of these
methods in a multi-day program.
In addition to reliability and validity, assessment procedures must be standardized; all
job candidates should receive the same treatment. Job interviews have historically not
met this criterion. However, because employers like interviews, standardized interview
methods such as behaviorally-based or structured interviews have been developed.
Selection procedures may be fairly straightforward or complex. A compensatory
strategy is one in which low scores on one test may be compensated by higher scores
on another test. In a non-compensatory strategy, each test has a minimum score which
must be achieved by the candidate. A hurdles strategy requires that candidate pass one
test before being considered for the next.
There is no one selection method that is best. A good personnel selection procedure is
based upon job criteria (KSAPCs) developed using a defensible rationale and on
assessments that are valid, provide reliable scores, and are directly related to the job
criteria.
