Using
Competency Models to Assess Employment Candidates and Employees
(The Importance of Validation & Consistent Treatment)
by Richard H. Beatty Validation of Selection Criteria When
determining the validity of competencies for use in either
candidate selection or employee assessment, there are two
distinct kinds of validity that should be considered. These
are:  Content Validity  Empirical
Validity Content Validity Content validity refers to the
knowledge, skills, and abilities needed for successful job
performance by virtue of the work itself. A good question
to ask when establishing whether a given competency is content-valid
is, "What is the degree of impact this competency has
on job performance? How critical is it?" Another factor
to consider is, "How often is this competency used
in performing the work"? When establishing selection
criteria, from a legal defensibility standpoint, it is best
to focus on "skills and abilities" rather than
"knowledge." The reason is, courts will question
whether or not the employer provides (or could have provided)
short-term training to develop the necessary knowledge.
As an employer, this argument can be tough to defend. In
order to be considered valid, job-content based criteria
must be "verifiable." There needs to be some statistical
evidence showing the evaluation criteria being used is "essential"
or "critical" to successful job performance. In
order for criteria to be considered "verifiable,"
the employer needs to show there has been an independent
validation of the data by multiple raters (usually 3 or
more) who are job knowledgeable. Job knowledgeable persons,
sometimes referred to as an "expert panel," are
persons who have actually performed the work, but can also
include others who supervise the work and are intimately
familiar with the requirements of the job. Process for Establishing
"Content Validity" The recommended process for
establishing content validity is as follows: 
Create an expert panel, 3 or more persons who are "job
knowledgeable"  Choose persons who have
actually performed the work as well as those who have supervised
it  Panel should always include two or more
current (or past) job incumbents  Review job
description to determine key challenges, responsibilities,
and expected results.  Use group process to
define a "preliminary list" of competencies felt
to be critical to job performance. (HR Technologies, Inc.
provides a "competency lexicon" and software to
facilitate this process.)  Have each panel member
independently (without discussion) assign a weighting to
the listed competencies using a 5-point weighting scale,
thereby reflecting the "relative" importance of
each competency to successful job performance. 
Use group process to fine-tune these weightings and arrive
at a final, consensus weighting for each competency. 
Finalize the competency list, with the group agreeing to
eliminate lower-weighted criteria and arriving at a final
competency set (i.e., the "assessment model").
 Focus the group primarily on selecting competencies
that are "skills and abilities," eliminating those
that are knowledge-based (especially those competencies
easily addressed through short-term training). 
Use the group to establish "behavioral anchors"
(i.e., definitions or examples of performance levels) for
each competency contained in the selection model, thus providing
an objective, uniform scale for assessing employees and
determining their competency "level." Empirical
Validity Empirical validity requires that evaluation criteria
be "statistically verifiable". This means the
employer must demonstrate there is a high degree of mathematical
correlation between a given competency and successful job
performance. If, using performance evaluation data, you
can demonstrate that a high percentage of top performers
possess a certain competency and can further demonstrate
this competency is relevant to their high performance level,
you can make a pretty strong case that the competency in
question is "empirically valid". In the case of
sales positions, for example, if you can show there is a
high degree of correlation between sales volume and certain
competencies, those competencies are considered to be empirically
valid. They are statistically relevant to sales performance.
In such cases, you need to be able to show that those who
posses these competencies consistently achieve high sales
volume (i.e., they consistently beat sales quota). On the
other hand, those who lack these same competencies consistently
deliver lower sales volume (i.e., they are consistently
below quota). Put simply, to test for the validity of the
competency selection model:  Employees who fit
the model consistently beat sales quotas  Those
who don’t fit the model consistently fall short of quota
Competencies that have been empirically validated are highly
defensible from a legal standpoint and can easily be demonstrated
to be valid criteria for either candidate selection or employee
assessment. Where possible, therefore, empirically validated
competencies need to be identified and added to those that
are job-content based to arrive at a final competency model.
Employee Assessment & De-selection Process When using
the competency model for de-selection purposes, it is important
employee evaluation be a "multi-rater" process.
Preferably there should be 3 or more raters, each having
first-hand knowledge of the employees to be rated. This
should obviously include the employee’s immediate supervisor
and other management personnel familiar with the quality
of the employee’s work. Additionally, where available, the
last two performance evaluations for each employee should
be provided to the members of the evaluation team, as well
as any other performance-related documentation contained
in the employee’s human resources file. Also, when using
empirically validated competencies, you should have the
last two years of measurable performance data available
for use in the assessment process. For example, if a sales
employee, empirical data might include:  Sales
volumes for last 2 years  Sales volume increases
for last 2 years (dollars and percentages) 
Established sale quotas (if any)  Performance
against quota (i.e., percent of quota achieved) for last
2 years The following process is then recommended for use
by the evaluation team in the actual evaluation of employees:
 Evaluation team reaches consensus on a uniform
employee evaluation scale (usually 1 to 4) based on employee
competency level. 4 = Superior level of competency (has
few, if any, peers) 3 = Above average level of competency
(competency is higher than most) 2 = Average (acceptable)
level of competency 1 = Below average (unacceptable) level
of competency  Where they exist, pre-established
"behavioral anchors" (i.e., pre-determined performance
levels for each competency, along with their respective
definitions) should be used in the place of the above general,
numerical rating scale.  Team members independently
(without discussion) evaluate each employee against the
competency model and record their ratings  Independent
rating scores are then averaged for each competency, and
the employee then receives a final score by multiplying
the average evaluator rating for each competency times its
pre-assigned weighting.  A "cut-off score"
is then established so that it yields the number of employees
needed to reach the program’s objective.  The
cut-off score is applied and employees whose scores are
below the cut-off are identified and placed on a "target
list." Adverse Impact Analysis Once employees are identified
for de-selection purposes, an analysis needs to be performed
to determine whether there has been adverse impact on any
particular "protected class" employee grouping
(i.e., race, creed, color, age, sex, national origin, or
disability). Where the percentage of a certain protected
class of persons selected for employment separation is disproportionate
to that of non-protected classes, the selection process
is said to have had an "adverse impact" on that
protected class grouping. In such cases, it is important
to identify and closely examine the specific competencies
that consistently caused the low rating of the affected
class members. Once identified, it is important to verify
that these competencies have been appropriately validated,
and are therefore legally defensible in the event of lawsuit.
Where such competencies have been empirically validated,
there should be no problem, and the company can feel free
to move ahead with little or no risk. Although not as readily
defensible in a court of law, content-validated competencies
need to be more closely examined to be sure they have been
properly validated from the legal perspective. In final
analysis, however, where evaluation criteria have been properly
validated (either empirically or on the basis of job content),
there should be little or no risk of an adverse impact lawsuit
being successful. In all cases, such validation should hold
up well in court. Due to the high volume of adverse impact-based
lawsuits and the ever-changing legal landscape as molded
by continuous court decisions, it is strongly recommended
that the entire validation process and results be thoroughly
reviewed and blessed by your corporate attorneys or outside
legal counsel before proceeding with employee notifications.
Differential Treatment The rule of thumb, when assessing
employees (or employment candidates), is "make sure
that you consistently treat all employees the same".
Application of certain criteria or reasoning to one employee
(or groups of employees) and not to others (i.e., "differential
treatment"), is an open invitation to time-consuming,
expensive litigation. Where "adverse impact" can
give rise to "group" class action lawsuits, "differential
treatment" can give rise to lawsuits by "individual"
employees who believe they have been "singled out".
The key to avoiding this type of lawsuit is consistent treatment
of all employees. If you apply certain criteria, standards,
or logic to one employee, make sure you apply the same criteria
to all other employees. For example, in de-selection, should
you elect to exempt an employee from a large sales loss
on the basis "she had no control", make sure to
exempt other employees with large sales losses if the same
basis and logic should apply. The best advice is, treat
all employees uniformly and consistently and the threat
of potential lawsuits on the basis of "differential
treatment" goes away entirely.
