Why Use Selection Mechanisms?
Choosing Selection Methods
Multiple factors need to be considered.
Specificity of skills required Risk of bad hire or mistakes made by employees Employee reactions
Level of adverse impact
Cost Administration time “Screening-in” vs. “Screening out” methods
Developing A Selection Plan
List each of the KSA’s required for the job Does it need to be assessed? What are the minimum qualifications?
List potential selection mechanisms for those KSA’s that need to be assessed along with costs and benefits.
Validity and reliability $$$ Costs Level of adverse impact
Detail the selection sequence Data to be collected at each point Criteria to be used to move applicants through the
sequence
Most Common Methods
Application Interview Education level Training and experience Reference checks Resumes Licensing and certification Biodata
Required for Every Selection Tool…
Equal opportunity (non-discriminatory)
Reliability
Validity(a) Test reflects the content of the job.
(b) Test predicts job performance.
Test Reliability
Reliability – consistency of the measureIf the same person takes the test again will he/she earn the
same score?
Potential contaminations: Test takers physical or mental state Environmental factors Test forms Multiple raters
How to determine reliability: Statistical techniques Test – retest reliability Inter-rater reliability Others
Relative Reliability of Measures

Test Validity
Validity – accuracy of the measure
Are you measuring what you intend to measure? (CONTENT)
OR
Does the test measure a characteristic related to job performance? (CRITERION)
Testing criterion validity:
Criterion – test predicts job performance in general Predictive – test predicts job future performance Concurrent – test predicts performance at time of test
How to determine validity: Conduct a job analysis Collect statistics Use outside evidence
The Goal of Selection: Maximize “Hits”

Reliability vs. Validity
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.
Effectiveness of Selection Methods
A survey of 201 HR executives rated selection methods on the effectiveness producing the best employees.

Steps in Pre-Employment Screening
1. Screen based on competency Written or simulation tests generally reliable and valid Benefits need to be balanced with costs
2. Use structured interviews Question objectivity and job relatedness Standardized administration Multiple raters
3. Verify applicants employment history/background check
4. Consider “screening-out” tool

Methods and Applicant Flow
Initial Selection
Initial Selection Resumes Application Forms
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 Consider “knockout” questions
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 Not particularly valid
Application Forms
How to ask non-discriminatory questions? You are always permitted to ask if applicant is qualified
and able to perform primary job duties. You should never ask questions that indicate protected
class status. Allow people to “self-select” as much as possible.
What if you need to collect demographic information for EEO purposes? Race, National Origin, Gender, Age etc
How to ask…
Do you have child-care for your children? Do you own a car? How old are you? Do you have a physical or mental disability? Height? Weight? What is your maiden name? Are you a U.S. citizen? Have you every been arrested? Do you smoke or use tobacco?
Resumes
Applicant controls the information Many examples of fraud or omission Up to 50% contain some inaccuracy What are possible indicators of resume fraud?
Jobs and education should be verified One question honesty test
Requirements for education and experiences should be job-related.
Potential Problems
NY Times Sept 12, 2005
Ronald L. Zarrella, the chief executive of Bausch & Lomb, claimed to have had a master's in business administration from New York University. Shares in the company dropped 3 percent the day the company divulged Mr. Zarrella's resume-fudging.
David J. Edmondson, the chief executive of RadioShack, was fired after a newspaper investigation showed that his resume was padded with two degrees in psychology and theology, degrees he never got from a university that was not even accredited.
Brad Fredericks, a co-founder of ResumeDoctor.com had his employees pull about a thousand of them that had been uploaded to the company Web site and check them for easily identifiable facts like job titles, education and dates of employment. ''What we found was shocking,'' Mr. Fredericks said. ''We discovered that 42.7 percent of them had significant inaccuracies.”
The Rutgers University Career Services office did an audit last year and found that 20 percent of students submitting resumes had inflated their grade-point averages.
