Chapter 1 and 2
Chapter 1: Brief History of the Use of Measures at Work
Overview of the historical evolution of measures used in workplace settings.
The central question throughout history: "Who should do which job?" emphasizing the shift from guesswork to systematic evidence based selection processes.
Ancient World (Before 500 CE)
Imperial China: The first government to use test scores for career selection, establishing written exams during the Han dynasty (206 BCE-220 CE).
Keju (civil-service examination): Instituted during the Tang dynasty (circa 618 CE), solidifying the foundations of civil service testing.
Song dynasty: Up to 400,000 candidates took local exams every three years, with only 1% reaching the final palace round.
Families invested heavily in tutoring.
Similar civil service systems emerged in Korea (958 CE) and Vietnam (1075 CE), illustrating the desire for structured pathways to office.
Mediterranean World: Utilized informal selection methods with performance-based tests:
Sparta: Endurance tests for boys.
Rome: Probation with armor to assess recruits for legions.
Middle Ages (500-1500)
Post-Rome, European craft guilds maintained skill standards, paralleling early criterion-referenced testing.
Monasteries: Held oral exams called disputations to ensure doctrinal accuracy involving rigorous questioning in Latin.
Emergence of universities: Incorporated disputations with structured timed exams, such as those at Oxford, marking an early focus on transparency.
Ming period in China further refined the keju, with answer sheets recopied by clerks to hide identity and evaluated by multiple graders, foreshadowing double-blind scoring.
Early Modern Era (1500-1800)
Demand for educated officers due to gunpowder and trade led schools to implement written tests (e.g., Prussian artillery school introduced trigonometry in 1720).
Critique of testing systems emerged, citing elitism but also a belief in the merits of open competition over patronage.
Birth of systematic psychological testing in the late 1800s, highlighted by Sir Francis Galton’s Anthropometric Laboratory opening in 1884.
Galton's creation of the correlation coefficient: A statistical measure that ranges from -1 to +1 indicating the strength and direction of relationships between traits.
Introduction of statistical techniques such as standard deviation and the exploration of hereditary genius, establishing groundwork for psychometrics.
James McKeen Cattell: Coined "mental test" to refer to timed tasks predicting academic performance; however, the correlation was weak, prompting insights into the necessity of validation.
Alfred Binet and Théodore Simon (1905): Developed the first true intelligence test to identify schoolchildren requiring additional assistance, introducing the concept of mental age.
Lewis Terman: Refined Binet's test into the Stanford-Binet test, contributing the concept of intelligence quotient (IQ), formulated as:
Binet advocated against determinism in scoring, laying ethical foundations still relevant today.
Frederick Taylor: Revolutionized workplace selection through scientific management, emphasizing skill and fit based evaluations over traditional affiliations, advancing job analysis as a key component of test design.
World War I and Mass Testing
U.S. military's need to swiftly classify recruits led to the development of Army Alpha and Beta tests guided by psychologist Robert Yerkes.
The Army Alpha: Multiple-choice questions focusing on vocabulary and arithmetic.
The Army Beta: Picture-based test for non-readers, accommodating a wider range of recruits.
Mass testing involved more than 1.7 million soldiers over eighteen months, marking significant advancements in psychological testing procedures.
Inter-war Growth of School and Job Tests (1919-1938)
Post-war proliferation of standardized assessments into civilian sectors lifted their legitimacy, leading educational institutions to adopt tools such as the Scholastic Aptitude Test (SAT) in the 1930s.
The rise of psychological testing as vital decision-making tools in hiring processes, leading to the establishment of journals and formal studies in industrial-organizational psychology.
World War II and the Assessment Center (1939-1945)
Development of nuanced testing tools during WWII (e.g., Army General Classification Test) and specific assessments for various roles, utilizing simulations and behavioral evaluations to analyze competencies.
The assessment center method emerged, assessing candidates through real work scenarios evaluated with structured checklists, establishing it as a prevalent selection method post-war.
Post-World War II
Expansion of psychological testing into corporate, educational, and governmental sectors, with standardized tests like GRE and SAT becoming commonplace.
Advances in data analysis and the rise of test publishers enhanced the sophistication of testing practices, led to considerations of fairness and ethical guidelines in test usage.
Validation studies: Linked assessments to job success, employing correlation/regression methodologies, pushing for continuous reform to accuracy and equity within testing frameworks.
Chapter 2: Using Measures at Work
Explores the necessity of measurement as organizations confront increasing complexity in decision-making.
Highlights the challenge faced globally by recruiters managing large applicant pools without clear information.
Presents five fundamental questions for using measures effectively in workplaces:
What Are We Measuring?
Who Needs to Be Part of the Process?
Where Will the Test Take Place?
When in the Employee Lifecycle Should We Use It?
Why Will the Results Help the Organization and the Test-taker?
Emphasis on psychological measures assessing characteristics such as cognitive ability, personality, motivation, emotional intelligence, integrity, leadership potential, and job-specific skills, focusing on the attributes critical to organizational success.
