The Selection Process

Obtaining Reliable and Valid Information

Reliability


The degree to which interviews, tests, and other selection
procedures yield comparable data over time and alternative
measures.
Validity

Degree to which a test or selection procedure measures a
person’s attributes.
Reliability: Basic Concepts

Observed score = true score + error



Error is anything that impacts test scores that is
not the characteristic being measured
Reliability measures error
Lower the error the better the measure
EEOC Uniform Guidelines
Reliability – consistency of the measure
If the same person takes the test again will he/she
earn the same score?
Potential contaminations:




Test takers physical or mental state
Environmental factors

Reliability vs. Validity
Approaches to Validation

Content validity

The extent to which a selection instrument, such as a
test, adequately samples the knowledge and skills
needed to perform a particular job.


Example: typing tests, driver’s license examinations, work
sample
Construct validity


The extent to which a selection tool measures a
theoretical construct or trait.
Are difficult to validate

Example: creative arts tests, honesty tests
Approaches to Validation

Criterion-related Validity

The extent to which a selection tool predicts, or
significantly correlates with, important elements of
work behavior.


A high score indicates high job performance potential; a low
score is predictive of low job performance.
Two types of Criterion-related validity


Concurrent Validity
Predictive Validity
Approaches to Validation

Concurrent Validity

The extent to which test scores (or other predictor
information) match criterion data obtained at about
the same time from current employees.


High or low test scores for employees match their respective
job performance.
Predictive Validity

The extent to which applicants’ test scores match
criterion data obtained from those applicants/
employees after they have been on the job for some
indefinite period.

A high or low test score at hiring predicts high or low job
performance at a point in time after hiring.
Reliability vs. Validity

Validity Coefficients




Reject below .11
Very useful above .21
Rarely exceed .40
Reliability Coefficients



Reject below .70
Very useful above .90
Rarely approaches 1.00
Why the difference?
Principles of Assessment











Don’t rely on a single method.
Use only fair and unbiased instruments.
Use only reliable instruments.
Use only valid instruments for a specific purpose.
Use only tools designed for a specific group.
Use instruments with understandable instructions.
Ensure test administration staff are properly trained.
Ensure test conditions are suitable for all test takers.
Provide reasonable accommodation.
Maintain confidentiality of results.
Ensure proper interpretation of results.
Steps in the Selection Process



Initial screening of application or resume
Employment testing, if applicable
Interview (may include multiple visits for
interviews)






HR
Supervisor/Team
Others
Contingent Offer
Background/Reference Checks
Medical/Drug screen
Application Forms
Only ask info related to job KSA’s



Link to job performance
Use thorough job analysis and validation techniques
Consider potential adverse impact
Careful collecting personal characteristics






Race, National Origin, Gender, Age etc.
Law assumes all questions are used in hiring
More is not necessarily better
Different applications for different jobs
Instructions and Disclaimers
Improve validity through weighted applications (WAB’s)
Online Applications

An Internet-based automated posting,
application, and tracking process helps firms to
more quickly fill positions by:


Attracting a broader and more diverse applicant pool
Collecting and mining resumes with keyword searches
to identify qualified candidates

Conducting screening tests online

Reducing recruiting costs significantly
Resumes

Applicant controls the information



Jobs and education should be verified


Many examples of fraud or omission
Up to 50% contain some inaccuracy
One question honesty test
Requirements for education and experiences
should be job-related.
Biodata Inventories


Generally reliable and valid
Series of questions on a wide variety of subjects




Background (e.g. hobbies, jobs, and education)
Situational questions
Personality and Values
Compared to a profile generated from successful
employees or database for occupations.
Examples of Biographical Questions

How many jobs have you held in the last five years?

Were you ever class president?

While growing up, did you collect coins?

About how many fiction books have you read in the past year?

How many hours a week do you spend studying?

At what age did you leave home?

How large was the town/city in which you lived as a child?

Did you ever build a model airplane that flew?

Were sports a big part of your childhood?

Do you play any musical instruments?
Employment Tests

Employment Test


An objective and standardized measure of a sample
of behavior that is used to gauge a person’s
knowledge, skills, abilities, and other characteristics
(KSAOs) in relation to other individuals.
Pre-employment testing has
the potential for lawsuits.
Classification of Employment
Tests

Cognitive Ability Tests

Aptitude tests


Achievement tests


Measures of a person’s capacity to learn or acquire skills.
Measures of what a person knows or can do right now.
Personality and Interest Inventories

“Big Five” personality factors:

Extroversion, agreeableness, conscientiousness, neuroticism,
openness to experience.
Classification of Employment
Tests (cont’d)

Physical Ability Tests


Job Knowledge Tests


Must be related to the essential functions of job.
An achievement test that measures a person’s level of
understanding about a particular job.
Work Sample Tests

Require the applicant to perform tasks that are
actually a part of the work required on the job.

The person was incompetent (rather than a competent
employee acting negligently).
Employer knew or should have known about the
incompetence.
Injury or harm was a foreseeable consequence of hiring
the incompetent employee.
Hiring of the unfit employee was proximate cause of the
injury or harm.





Specific job-related information
Letters of reference

Background Investigations

Organizations using credit reports must:
1.

3.
4.
5.
Check state laws to see if credit reports can legally be
used.
Advise and receive written consent from applicants if
a report will be requested.
Provide a written certification to the consumer
reporting agency as to the purpose of the report.
Provide applicants a copy of the consumer report as
well as a summary of their rights under the CCRRA.
Must provide an adverse-action notice a person if that
person is not hired and contact information related to
the reporting agency.
Criminal Background Checks

Employers can obtain criminal background information by:
(1) Asking applicants for certain information during the interview process
or on a job application
(2) Obtaining criminal record information from a state agency (with the
consent of the applicants)
(3) by hiring an investigator or security firm

Before the information is gathered, employers should have specific
guidelines for how they will use the information.
Decision Criteria
The hiring official will determine on a case-by-case basis whether the
individual is qualified based on factors such as:







Specific duties of the position;
Number of offenses;
Nature of each offense;
