The company, staff and figures are composites written for a model paper; legal and research material comes from the sources listed.

Industrial and organizational psychology brings research on human behavior into the workplace. One of its oldest tasks, choosing whom to hire, is also one of the most legally regulated. This paper introduces the field and the employment laws that shape it through a company facing a large hiring push.

The Company

Desert Sun Solar, a composite residential solar installer in Phoenix, Arizona, has won contracts that require 120 new installers within six months. Andrea Kim, the HR director, proposes two screens: a high school diploma or equivalent, and a twelve-minute general mental ability test that the company's previous owner used for office staff. Her reasoning is speed and quality. Operations managers support the plan; a regional manager worries that it will exclude experienced roofers and electricians' helpers who never finished school.

What I-O Psychology Is

Vinchur and Koppes (2011) traced the field's development from early twentieth-century applications of psychology to advertising and personnel decisions, through large-scale testing of soldiers in the two world wars, to the growth of organizational psychology after mid-century with its attention to motivation, leadership and groups. Over time, the field built a body of research and professional standards for valid, fair selection, and legal developments in the 1960s and 1970s made those standards central to practice.

Today, I-O psychologists work on job analysis, selection, training, performance management, motivation, leadership, teams, organizational change and well-being, in companies, consulting firms, government and universities.

What the Law Requires

Title VII, part of the landmark 1964 federal civil rights law, bars employers from basing hiring, pay or promotion on an applicant's race, skin color, faith, sex or country of birth or ancestry. Federal age law shields applicants and employees aged forty and up, and the Americans with Disabilities Act bars bias against people with disabilities who can do the job's core work and calls for reasonable adjustments. Arizona law adds related protections.

Discrimination can take two forms. Disparate treatment is intentional, treating someone differently because of a protected characteristic. Disparate impact covers rules that look even-handed and apply to every applicant yet shut out one protected group far more often than others, without a business reason rooted in the work.

The Case That Defined Disparate Impact

In Griggs v. Duke Power Co., decided by the Supreme Court in 1971, a North Carolina power plant made a diploma, plus passing marks on two off-the-shelf aptitude tests, the price of moving out of its lowest-paid department. Black employees were screened out far more often, no evidence linked either hurdle to doing those jobs well and white workers hired before the rules existed were doing the same jobs satisfactorily without meeting them. The justices ruled unanimously that a hiring rule which looks even-handed but shuts out one group is unlawful unless the employer shows it measures what the job demands, and that meaning well is no defense.

A diploma requirement looks neutral on paper; the question the law asks is whether installing panels on a roof actually requires one.

Applying Griggs to Desert Sun

Andrea's proposal closely resembles the requirements in Griggs. A diploma requirement may screen out applicants from groups with lower graduation rates, and general aptitude tests often show subgroup differences in average scores. Neither has been linked to installer performance at Desert Sun. If, for example, 60 percent of white applicants passed but only 40 percent of Black or Hispanic applicants did, that two-to-three ratio would fall under the federal four-fifths benchmark for flagging adverse impact, and the company would need evidence that the requirements are job related.

Research on Fair and Valid Alternatives

Ployhart and Holtz (2008) reviewed strategies for reducing racial, ethnic and sex differences in selection while maintaining validity. Approaches with the most support included measuring a broader range of job-relevant abilities and characteristics rather than relying on cognitive ability alone, using methods such as work samples and structured interviews and reducing reading demands not required by the job. Simply removing valid predictors tended to reduce prediction, while combining several valid measures often preserved it with less adverse impact.

A Better Plan

First, conduct a job analysis: interview experienced installers and supervisors, observe installations and list tasks, such as working safely at heights, reading wiring diagrams, lifting panels and communicating with homeowners, and the knowledge, skills and abilities they require. Second, choose tools linked to that analysis: a hands-on work sample, such as mounting a rail and connecting a panel under supervision; a structured interview on safety and teamwork; and a short, job-specific test of reading diagrams. Third, drop the diploma requirement unless the job analysis shows it is needed. Fourth, track selection rates by group and review them quarterly. Fifth, provide accommodations, such as alternative test formats, when requested.

Age and Disability Questions

The hiring push raises two further legal issues. Some managers prefer younger applicants for rooftop work, but the Age Discrimination in Employment Act bars screening out applicants forty and older because of age; the job analysis should define the physical demands, such as lifting fifty pounds and climbing ladders, and everyone should be assessed against them. Under the Americans with Disabilities Act, the question for an applicant with a disability is whether the core duties of the job can be done, with workable adjustments if needed, so the company must decide which tasks are truly essential before any medical or physical screening, which may occur only after a conditional offer.

What This Plan Gains

The plan protects against legal risk, but it also widens the applicant pool to include experienced tradespeople and is likely to predict performance better, because the tools measure what the job requires. The regional manager's concern and the law's requirement point in the same direction, and a broader, better-matched pool should also reduce early turnover, which costs the company far more than a slower first month of hiring.

Conclusion

I-O psychology developed tools and standards for fair, valid employment decisions, and employment law made those standards essential. Griggs established that neutral requirements with unequal effects must be shown to be job related. For Desert Sun Solar, a job analysis followed by work samples, structured interviews and monitored selection rates offers a path that is fairer, legally sounder and more predictive than a diploma and a general test.
