EEOC Statements on Pre-Employment Inquiries
“Although Title VII does not make pre-employment inquiries concerning race, color, religion or national origin per se violations of the law, the Commission’s responsibility to equal employment opportunity compels it to regard such inquiries with extreme disfavor.”
“ … in the investigation of charges alleging the commission of unlawful employment practices, the Commission will pay particular attention to the use by the party against whom charges have been made of pre-employment inquiries concerning race, religion, color, or national origin, or other inquiries which tend directly or indirectly to disclose such information. The fact that such questions are asked may, unless otherwise explained, constitute evidence of discrimination, and will weigh significantly in the Commission’s decision as to whether or not Title VII has been violated”
Application Blanks
• Content of items (use of job analysis)
• Number of application blanks (one for each position or job category)
• Legal issues
• Image of organization (e.g., format, recruitment issue, perceived fairness)
• Accuracy of data
Applicants overstated length of employment and past salary on application forms (Goldstein, 1971) One serious lie on 25% of application forms and resumes (LoPresto, Mitcham, & Ripley,1986) 40% to 60% candidates overstated their qualifications on resumes (George & Marett, 2005) Most frequent falsifications are job history, job duties, educational record, position title, and previous salary (Broussard and Brannen, 1986)
Increasing Application Form Accuracy
• Inform applicants in verbally and in writing, that the information they furnish will affect their employability
• Inform applicants that the data they provide will be thoroughly checked
• Require applicants to sign a statement certifying the accuracy of the information they provided on the form.
• Include warnings of penalties (not being hired or termination upon discovery) for deliberate falsification
• Include a statement that the application does not create a binding obligation of employment for any specific period of time

In 2012, the EEOC issued guidelines on the use of arrest and conviction records for making selection decisions, its first update since 1990.
Refusing to hire those with arrest records is not considered to be justifiable. However, if an individual's behavior underlying an arrest makes the person unfit for a given job, then a decision to not hire may be legitimate.
Conviction records are generally easier to defend from a legal perspective. But, the EEOC stresses the consideration of the following three factors:
1) the nature and severity of the offense, 2) the amount of time that has passed since the conviction (or completion of one's sentence), and3) the nature and type of job sought.
The EEOC suggests not asking about conviction records on application forms. If included, such questions ought to be restricted to convictions “for which exclusion would be job related for the position in question and consistent with business necessity.” See: http://www.eeoc.gov/laws/guidance/arrest_conviction.cfm

SHRM Credit Check Survey Research Summary
• The use of credit background checks in employment decisions has not changed in any discernable way over the past 6 years.
• Most organizations do not conduct credit background checks on all job candidates.
• Organizations conduct credit background checks for those positions where this information is most job-relevant.
• Employers place lower relative importance on credit background checks than other job-related factors in making hiring decisions.
• Employers do not use credit background checks to screen out mass numbers of candidates in the early phases of the application process.
• Credit background check results are seldom used as a definitive hiring criterion.

Meta-Analysis
A recent study found credit scores to be predictive of certain work-related outcomes and Big 5 personality scores. The authors found that credit scores were significant and negatively related to supervisor ratings of:
• Task performance • Employee engagement in OCBs
Credit score were also predictive of Big 5 personality scores:
• Greater conscientiousness • Low agreeableness
• But, credit scores were not found to predict supervisor ratings of: • workplace deviance (e.g., theft, aggressiveness)
However, the authors caution the use of credit scores absent data demonstrating their job relatedness for certain jobs and the potential for adverse impact.

Description: During my senior year (2005–2006), I wrote a senior research thesis as a partial requirement for graduation with honors in psychology. I designed a research study to investigate the effects of interviewer race on interviewee performance in a structured interview. I personally designed the research study and conducted it in a metropolitan police department. White and African-American applicants for the job of patrol police officer were randomly assigned to White and African-American interviewers. After conducting an analysis of the patrol police job, a structured interview schedule was developed. The various interviewee-interviewer racial combinations were then compared in terms of their performance in the structured interview. I consider the vast majority of the work (80 percent) to be my own. My major professor accounted for about 20 percent of the work. Her work consisted of helping to obtain site approval for the research, helping to design the study, and reviewing my work products.

T&E Recommendations
Reference Checks(Exceptionally common technique; e.g., 95% usage by organizations)
Basic Purposes:
• Verify information provided by the applicant (check for inconsistencies)
• Uncover unreported or additional information (over ½)
• Predict job performance (pass or fail decisions made (52%)
Types of Information Collected
• Employment dates
• Rehire?
• Salary history
• Absenteeism, tardiness
• Qualifications for a certain type of job or work
Sources of Reference Data
• Supervisor (most common and most useful)
• Personal reference
• Agencies (e.g., credit ratings)
• Public Records (criminal background, driving records, court records, workers compensation)
• Educational background (verification)
Reference Check Methods
In-Person (e.g., interview)
• Costly, time consuming
• Used in jobs that involve the concern for risks (e.g., security, $)
• Can elicit different types of information (differences between in-person and written reference information)
Mail (or e-mail)• Low return rate with use of “snail” mail (e.g., 56 – 64%) (many chose to set up phone reference checks via email)
• Standardized questions, format
• Written record of responses
• Ensure confidentiality of responses (signed statement by applicant)
Telephone Checks(More frequently used than written references)
• Allows follow-up or clarification of answers given
• Less resistance to giving certain types of information can be collected
• Relatively quick process • Important data can be gleaned from various verbal cues (e.g., pauses, hesitations, voice inflections, voice level, intonations)
• Relatively high return rate (especially if time was set earlier)
• Better responsiveness, more interactive nature of the method
• More confidence in the identity of responder
Reference Check Recommendations
• Use of job-related questions (e.g., KSAs from a job analysis)
• Use of multiple reference check forms (job specificity)
• Follow provisions contained in the Uniform Guidelines (e.g., regarding fairness, validity)
• Behaviorally-focused and objective set of questions
• Get written permission for applicants
• Training of interviewers (phone, interview) and recordkeeping
• Ask for additional references if one’s submitted not available
• Verify information that is collected!
Usefulness of Reference Information
• Relatively low validity; relationship to performance measures (e.g., .14, .16)
• Relatively low interrater reliability (e.g., .40, but sometimes from different sources)
Most useful if:
• Data collected from immediate supervisor
• Referee knows applicant well (chance to observe job behavior) and have similar demographic characteristics
• Similarity between the prior job and the one being applied for

Bio-Data [Why does it work?]
• Use of life history items e.g., personal background, life experiences, interests (past behavior is best predictor of future behavior)
• Only relevant (empirically significant) items/constructs are selected
• Correlation between BIB content and criterion
• Wide range of information (lots of different questions and types)
• Situational specificity
• Need large sample to construct properly
• Assumption of a “correct” life history
• Pure empirical approach (e.g., versus content approach)
• Legal issues (e.g., adverse impact, validity, reliability)
Some Bio-Data Issues
Eliminate an item from the Bio-data inventory if the item:
• Exhibits little response variance
• Has a skewed response distribution
• Is correlated with protected-group characteristics such as ethnicity
• Has no correlation with other items thought to be measuring the same life history construct
• Has no correlation with the criterion (no item validity)
