Hiring Success The Art and Science of Staffing Assessment and Employee Selection
Steven Hunt
In a sentence
A non-technical guide explaining what staffing assessments are, why they work, and how to use them to make more accurate, efficient, fair, and legally defensible hiring decisions.
Staffing assessments—personality measures, ability tests, background checks, structured interviews, and work simulations—are used to evaluate millions of job candidates each year, yet few people understand how they actually work or why they outperform intuition-based hiring. Written by industrial-organizational psychologist Steven Hunt, Hiring Success bridges the gap between dense scientific research and oversimplified vendor white papers, offering a thorough but accessible explanation of assessment science. The book shows that human behavior is remarkably consistent over time, which is why well-designed assessments can predict future job performance months or years in advance far more accurately than unstructured interviews or resume reviews. It walks readers through what assessments measure (what candidates have done, can do, and want to do), how to evaluate their validity and business value, how to answer common criticisms, and how to integrate assessments into hiring processes for both entry-level and professional jobs. The result is a practical toolkit for anyone who wants to hire better employees while treating candidates fairly.

- Statistics
- Systems
- Strategy
Tags
The model
A causal model describing how the design and use of valid staffing assessments, applied under favorable conditions (candidate pool size, performance variance), lead to measurement of candidate attributes that predict job-relevant behaviors and ultimately improve hiring accuracy, workforce quality, and organizational financial outcomes.
Assessment Validitydesign lever
The degree to which a staffing assessment accurately measures job-relevant candidate attributes and predicts actual job performance and tenure, established through face, content, criteria, and construct validation.
Assessment Design and Deployment Qualitydesign lever
The extent to which an assessment is well-built, based on job analysis, standardized in administration, and appropriately scored (including localized and non-linear scoring), enabling consistent and accurate collection and interpretation of candidate data.
Candidate Pool Sizecontextual condition
The number of eligible candidates considered for each job opening relative to the number of openings; larger pools mean more selection decisions per hire and greater potential value from assessments.
Job Performance Variancecontextual condition
The difference in financial value between high-performing and low-performing employees in a job, reflecting both the value of great hires and the cost of bad hires; the higher the variance, the more value assessments provide.
Candidate Attributespsychological state
The enduring characteristics of candidates measured by assessments, including what they have done (experience), what they can do (personality and ability), and what they want to do (motives and interests), many of which are genetically influenced and stable over time.
Job-Relevant Employee Behaviorsbehavioral pattern
The specific productive and counterproductive behaviors employees display on the job that are driven by their underlying attributes and that in turn determine job performance outcomes.
Hiring Decision Accuracyoutcome metric
The degree to which selection decisions correctly identify candidates who will succeed and screen out those who will fail, improved by systematic, unbiased collection and interpretation of candidate information.
Candidate Reactions and Experiencepsychological state
How favorably candidates perceive the assessment process in terms of job relevance, fairness, length, and invasiveness, affecting whether they remain in the process and their attitudes toward the employer.
Workforce Quality and Performanceoutcome metric
The overall level of employee performance and productivity across a workforce, which improves gradually as valid assessments are used to hire better-suited employees over time.
Organizational Financial Outcomesoutcome metric
The bottom-line business results—profitability, revenue (Human Value Added), reduced turnover costs, and staffing efficiency—that result from hiring higher-quality employees through valid assessments.

The story
The reader A hiring manager, recruiter, or HR professional who wants to hire employees who will succeed in their jobs.
External problem
Making hiring decisions with limited, imperfect information leads to costly bad hires and missed good candidates.
Internal problem
They feel uncertain and skeptical about whether staffing assessments really work and worried about using tools they don't understand.
Philosophical problem
Denying or granting someone a job is a serious decision that shouldn't be based on subjective bias, gut feel, or irrelevant factors like appearance or personal connections.
The plan
- Understand what assessments measure and why consistent human behavior makes them work.
- Learn the different types of assessments and their strengths and limitations.
- Evaluate assessment effectiveness through validity (face, content, criteria, construct).
- Define job performance via job analysis before choosing assessments.
- Address common criticisms honestly and weigh benefits against risks.
- Choose assessment methods matched to your hiring situation and integrate them into a multi-hurdle hiring process.
Success
- A higher-quality, more productive workforce hired through more accurate decisions.
- More efficient, fair, and legally defensible staffing decisions.
- Happier employees placed in jobs that fit their talents and interests, and more satisfied hiring managers.
At stake
- Costly catastrophic hires and disruption to co-workers, customers, and families.
- Systematically decreased workforce quality from using ineffective or misused assessments.
- Legal risk, offended candidates, damaged employer brand, and denied opportunities to qualified people.
Questions this book answers
