Selection Tests
Do you remember?
Campbell’s performance model?
The most theoretically valid personality model? 5 factor model
Conscientiousness is the best personality predictor for job performance
Cognitive ability is the best predictor for job performance
Overview of Tests
Test
Defined as an objective and standardized procedure for measuring a psychological construct
using a sample of behavior
Can assess a variety of psychological constructs
Using a variety of methods
Ex: what should be measured in evaluating a job candidate? And how can we measure them?
Test Used in Personnel Selection
Tests can be used to measure psychological constructs and the score of tests can be used to
predict work behaviors (potential)
In order to make a good use of tests, you must clarify:
The goal of tests: to select new personnel or promote
What construct do you want to measure
What criterion do you want to predict
What is the magnitude of the relationship between the construct and the criterion?
Characteristics of the test:
Does it measure what you want to measure? Construct validity
Does the score of this test predict what you expect to predict? Predictive validity
Types of tests
Speed vs power test
Speed: test with a rigid and demanding time limits
Speed tests yield greater variability among candidates, allowing for more effective
prediction
Shortcoming 1: does the job really have such time pressure?
Shortcoming 2: adverse impact (information-processing speed varies across ages, ex:
younger people finish quicker than older people)
Americans with disabilities act (1990) requires additional time to complete a test
Power: a test with no rigid time limits, enough time is given for a majority of the test takers
to complete all of the test items

Performance test: Work sample, stimulation
Test Battery
Test battery is a collection of test that usually assess a variety of different attributes
Measure a single area – cognitive battery measures reasoning, memory, and comprehensive
Measure conceptually different areas – a battery that includes a measure of cognitive ability,
a personality test, a physical ability test, and a test of vocational interests
Take during a single testing period or in several short period of times
Concerns about tests selections
What should be noted when choose selection test
Validity
Fairness
Applicability
Cost
Cognitive Ability Tests
Allow a person to show what he or she knows, perceives, remembers, understands, or can
work with mentally
Problem identification
Problem solving
Perceptual skills
Development or evaluation of ideas
Remembering what one has learned through general experience or specific training
High validity predicting job performance (0.5 to 0.7)
Test batteries for cognitive ability – ASVAB (usually used for the army for reasoning) or GATB
(used by federal government for problem solving)
Knowledge tests: the extent to which you know a given subject
Tests and Differential Validity
Differential validity: describe the hypothesis that employment tests are less valid for minority
group members than non-minorities
Is this test fair across all groups?
Adverse impact: a serious concern for selecting employees in US
Ability test is relatively fair compared to other tests
Physical Ability Tests
Physical ability test: test if an individual is capable to perform a certain physical behavior
required by the job
Ex: firefighter
