Impact of Staffing Practices on
Firm Performance
• High performance work practices
– Include use of formal job analyses, selection
from within for key positions, & use of formal
assessment devices for selection
• Staffing practices have positive associations
with firm performance
6. 6
Staffing from
International Perspective
• Job descriptions used universally
• Educational qualifications & application
forms widely used for initial screening
• Interviews & references are common post-
screening techniques
• Cognitive ability tests used less frequently;
personality tests used more frequently
7. 7
Module 2: Evaluation of
Staffing Outcomes
• Validity: Accurateness of inferences made
based on test or performance data
• Validity designs
• Criterion-related: the one you can apply the most at
the organizational level (this provides a coefficient)
• Content-related: whether we are capturing the entire
domain of performance within one test
• Construct-related:
9. 9
Selection Ratio (SR)
• Selection Ratio (SR)
– Index ranging from 0 to 1 that reflects the ratio
of available jobs to applicants
n = number of available jobs
N = number of applicants assessed
SR = n/N
10. 10
Selection Decisions
False positive
• Applicant accepted but performed poorly
False negative
• Applicant rejected but would have performed well
True positive
• Applicant accepted & performed well
True negative
• Applicant rejected & would have performed poorly
11. 11
Cut score or cutoff score
• Specified point in distribution of scores
below which candidates are rejected
• Raising cut score will result in fewer false
positives but more false negatives
• Strategy for determining cut score depends
on situation
13. 13
Establishing Cut Scores
• Criterion-referenced cut score
• Consider desired level of performance & find test
score corresponding to that level
• Looking at actual performance and have SME (ex:
in order for a person to excel on a job they have to
answer this set of questions correctly)
• Norm-referenced cut score
• Based on some index of test-takers’ scores rather
than any notion of job performance
• Pick a # that is based on how the tester’s are
performing on the exam (on average our applicants
answer 80% correctly)
14. 14
Utility Analysis
• Assesses economic return on
investment of HR interventions like
staffing or training
• Utility analysis can address the cost/benefit
ratio of one staffing strategy versus another
15. 15
Utility Analysis
• Includes consideration of the Base Rate, which is
the percentage of the current workforce
performing successfully
– If performance is already high, then new staffing
system will likely add little to productivity
• Utility analysis calculations can be very
complex- as this increase it decreases the
likelihood that people will actually use
these
16. 16
Feelings of unfairness regarding
Staffing Strategies can lead to:
• Initiation of lawsuits
• Filing of formal grievances with
company representatives
• Counterproductive behavior
17. 17
Module 3: Practical
Issues in Staffing
• Staffing Model
– Comprehensiveness
• Enough high quality information about candidates to
predict likelihood of their success
– Compensatory
• Candidates can compensate for relative weakness in
one attribute through strength in another one,
providing both are required by job
18. Table 6.2: The Challenge of Matching
Applicant Attributes and Job Demands

Combining Information
• Clinical decision making
– Uses judgment to combine information &
make decision about relative value of
different candidates
• Statistical decision making
– Combines information according to a
mathematical formula
21. 21
Combining Information (cont'd)
• Hurdle system of combining
scores
– Non-compensatory strategy:
individual has no opportunity to
compensate at later stage for low
score in earlier stage
– Establishes series of cut scores

22. 22
Hurdle System of Combining Scores
• Constructed from multiple hurdles so
candidates who don’t exceed each of the
minimum dimension scores are excluded
from further consideration
• Often set up sequentially
• More expensive hurdles placed later
• Used to narrow a large applicant pool
23. 23
Combining Information (cont'd)
• Compensatory approach
– Multiple regression analysis
• Results in equation for combining test scores into a
composite based on correlations of each test score
with performance score
• Cross-validation
– Regression equation developed on first sample
is tested on second sample to determine if it
still fits well
25. 25
Score banding
• Individuals with similar test scores can
be grouped together in a category or
score band
• Selection within band can be made
based on other considerations
• Score Banding is controversial
26. 26
Score Banding
• Score Banding uses the Standard error
of measurement (SEM) for the test
– SEM provides a measure of the amount
of error in a test score distribution
– Function of reliability of test &
variability of test scores
27. 27
Score Banding
• Fixed band system
– Candidates in lower bands not considered
until higher bands have been exhausted
• Sliding band system
– Permits band to be moved down a score
point when highest score in a band is
exhausted
28. 28
Subgroup Norming
– Develop separate lists for individuals in
different demographic groups who are
then ranked within their respective group
– In general, subgroup norming is not
allowed as a staffing strategy
29. 29
Selection vs. Placement
• Sometimes, the challenge is to place an individual
rather than simply select an individual
• Placement
– Process of matching multiple applicants & multiple job
openings
– Strategies
• Vocational guidance
• Pure selection
• Cut & fit
31. 31
Deselection
• 2 typical situations
– Termination for cause
• Individual is fired for a particular reason
• Generally not unexpected
– Layoff
• Job loss due to employer downsizing or
reductions in force
• Often occurs with little or no warning
32. 32
Large Staffing Projects
• Concessions must be made: Labor intensive
assessment procedures are often not feasible
• Cost of testing can be quite expensive
• Fairness is a critical issue
• Standard, well-established, & feasible selection
strategies are important
33. 33
Small Staffing Projects
• Luxury of using wider range of assessment
tools
• Adverse impact is less of an issue
• Fairness is still a key issue
• Rational, job-related, & feasible selection
strategies are important
34. 34
Module 4: Legal Issues in
Staffing Decisions
• Charges of employment discrimination
– Involve violations of Title VII of 1964 CRA,
ADA, or ADEA
– I-O psychologists often serve as expert
witnesses in these lawsuits
– Consequences can be substantial
– Most often brought by individual claiming
unfair termination
35. 35
Intentional Discrimination or
Adverse Treatment
• Plaintiff attempts to show that
employer treated plaintiff differently
than majority applicants or employees
36. 36
Unintentional Discrimination or
Adverse Impact (AI)
• Acknowledges employer may not have
intended to discriminate against
plaintiff but employer practice had AI
on group to which plaintiff belongs
37. 37
Determination of Adverse Impact
• Burden of proof on plaintiff to show:
a) he/she belongs to a protected group, &
b) members of protected group were
statistically disadvantaged compared to
majority employees
38. 38
“80%” or “4/5ths” rule
– Guideline for assessing whether there is
evidence of Adverse Impact (AI)
– Plaintiffs must show that protected group
received only 80% of desirable outcomes
received by majority group in order to meet
burden of demonstrating AI
– Results in AI ratio
39. 39
“80%” or “4/5ths” Rule (cont'd)
• Can be substantially affected by sample
sizes
• Burden of proof shifts to employer once AI
is demonstrated
40. 40
Social Networking Sites
and the Workplace
• Employees (or applicants) posting information on a social
networking site (e.g., Facebook, Twitter) that is accessed by an
employer have been increasingly getting in trouble.
• Job candidates who have been found to post on SNS that they
like to “shoot people” or “blow things up” have been removed
from hiring consideration.
• Employment lawyers are still debating the legality of
employment decisions based on information on social
networking sites.
Editor's Notes
Want to establish a relationship with these tests and overall work performance
Access the reliability and validity
Top one is a perfect relationship between the predictor and criterion (never occurs-this is ideal)
Chart to the right is the opposite of ideal because we have a whole bunch of different scores on a test and it turns out our test does not predict at all what performance would be
Chart on the left shows a range of what their performance might be
How many openings do you have, and how many applicants do you have for that particular job-you can create a ratio between #of applicants and # of openings, this is the selection ratio
You want a small number so you have more people to choose from
As the selection ratio decreases, the likelihood of us selecting a really good employee increases
Increase recruiting efforts by making our job known on many different mechanisms and decrease the number of openings that you have
At what point within this distribution of scores we have at what point are we not going to hire below this score?
Cutoff score
As we increase the cut score, the likelihood of a false negative increases
When you decrease the cut score, you increase the likelihood of a false positive
Look at the performance of the people you have hired in the past
Compare the top performing employees to the bottom performing employees
Base rate: how well are the employees actually performing
If you lay someone off, you are making a false positive because that person may actually be a better performer than we thought he/she was
As you make concessions, what happens to your staffing decisions? What happens to the errors you make?
More error, more false positives and potentially false negatives
This is adverse impact
If an organization unintentionally hires all white people
If the selection ratio of the minority group falls below 80%, rather than that against the majority group, adverse impact has occurred
.08 for no adverse impact if there are 100 applicants
