Personnel Selection Adding Value Cook

The model

This model synthesizes the core argument of 'Personnel Selection', positing that the implementation of a selection system with high aggregate predictive validity (a design lever) leads to a workforce with superior job-relevant attributes (e.g., GMA, Conscientiousness). These attributes, in turn, drive positive individual work behaviors and outcomes, which ultimately enhance overall organizational performance. The model is constrained by fair employment legislation and moderated by factors like job complexity.

10. ch10Assessment centres

    This chapter explores assessment centres (ACs) as a structured method for evaluating candidates' job-related competencies through complex, multi-dimensional exercises, while critically examining their validity and effectiveness.

11. ch11Emotional intelligence and other methods

    Emotional intelligence (EI) has gained attention as a significant predictor of workplace success; however, its effectiveness and reliability compared to other assessment methods are challenged in this chapter.

    • Emotional intelligence, while popular, has not proven to be a consistent predictor of work performance.
    • The effectiveness of EI assessments may be significantly compromised by self-reporting biases and the ease of faking results.
    • Other methods such as situational judgement tests boast better validity in predicting workplace outcomes than emotional intelligence measures.
    • The reliance on education as a selection tool shows diminishing returns, particularly in the long term, challenging its role in recruitment strategies.

12. ch12Criteria of work performance

    This chapter critically examines the standards by which employee performance is evaluated, arguing that commonly used criteria from supervisor ratings to objective measures lack reliability and validity and may perpetuate bias.

    • Criteria for work performance have inherent imperfections and should be reassessed regularly to maintain relevance.
    • Supervisor ratings, while convenient, often suffer from significant bias and error.
    • Objective performance measures may not capture the full complexity of an employee’s contributions to organizational success.
    • Recent trends toward recognizing organizational citizenship and counterproductive behaviors reflect a necessary evolution in performance evaluation.

13. ch13Minorities, fairness and the law

    This chapter examines the evolution and implications of fair employment laws in the USA and UK, highlighting the disparities and challenges minority groups face in the hiring process.

    • Fair employment laws were established to combat discrimination based on ethnicity, gender, and disability, yet they frequently trigger unforeseen adverse impact.
    • Adverse impact (AI) occurs not through intentional discrimination, but through recruitment practices that unintentionally marginalize minority candidates.
    • Employers bear the burden of proof to demonstrate that their hiring practices are indeed valid and do not produce adverse impact, which can be a complex and expensive process.
    • The requirement for job-relatedness in selection methods must be upheld to mitigate the risk of discrimination, as established in key legal cases like Griggs v. Duke Power Company.
