EMPCO Assessment Methods 3 — Questions and Answers
Question 1: What is the 'four-fifths rule' used to detect in employment selection?
- Whether a test has at least 80% content validity
- Whether a protected group's selection rate is less than 80% of the highest-rated group's rate (Correct answer)
- Whether at least four out of five assessors agree on a candidate rating
- Whether a candidate scores above 80% on a job knowledge test
Correct answer: Whether a protected group's selection rate is less than 80% of the highest-rated group's rate
The four-fifths (or 80%) rule is a practical guideline indicating adverse impact when a protected group's selection rate falls below 80% of the majority group's rate.
Question 2: In occupational health assessments, a 'fitness-for-duty' evaluation is most appropriately ordered when:
- A new hire needs standard onboarding paperwork completed
- An employee's behavior or performance raises concerns about their ability to safely perform their job (Correct answer)
- A candidate applies for a promotion without prior medical history
- A company wants to reduce its insurance premiums proactively
Correct answer: An employee's behavior or performance raises concerns about their ability to safely perform their job
Fitness-for-duty evaluations are triggered by observable evidence suggesting an employee may be unable to perform their job safely due to a medical or behavioral condition.
Question 3: Which type of assessment asks candidates to perform actual job tasks under standardized conditions to evaluate competence?
- Work sample test (Correct answer)
- Personality inventory
- Cognitive ability test
- Biodata questionnaire
Correct answer: Work sample test
Work sample tests directly simulate job tasks, offering high face validity and strong predictive validity for on-the-job performance.
Question 4: When an EMPCO physician conducts a pre-placement examination, the physician's role is primarily to:
- Decide whether to hire the candidate based on overall qualifications
- Determine whether the candidate can safely perform the essential functions of the offered position (Correct answer)
- Provide a general wellness report to the candidate's personal physician
- Identify pre-existing conditions to exclude the candidate from benefits
Correct answer: Determine whether the candidate can safely perform the essential functions of the offered position
The pre-placement physician assesses medical fitness relative to the specific essential functions of the job, not overall hiring suitability.
Question 5: Predictive validity is established by:
- Comparing test scores to job performance measures collected after hiring (Correct answer)
- Having subject matter experts review the test content for accuracy
- Administering two forms of the test simultaneously and correlating results
- Calculating the percentage of correct answers across all test takers
Correct answer: Comparing test scores to job performance measures collected after hiring
Predictive validity uses a criterion-related design, correlating pre-hire assessment scores with subsequent job performance outcomes.
Question 6: Which accommodation under the ADA is an employer required to provide to a qualified candidate with a disability during the assessment process?
- Waiving all assessment requirements permanently
- Reasonable modifications that do not create undue hardship for the employer (Correct answer)
- A separate, lower standard of evaluation for disabled candidates
- Immediate hiring regardless of assessment results
Correct answer: Reasonable modifications that do not create undue hardship for the employer
The ADA requires reasonable accommodations in the assessment process, such as extended time or alternate formats, unless they impose undue hardship.
Question 7: A cognitive ability test used for pre-employment selection is most likely to predict:
- A candidate's physical endurance on a manual labor task
- General learning ability and performance across a wide range of jobs (Correct answer)
- A candidate's specific technical skill level in a narrow specialty
- The candidate's emotional stability under interpersonal conflict
Correct answer: General learning ability and performance across a wide range of jobs
Cognitive ability tests are among the strongest predictors of trainability and performance across diverse job types, reflecting general mental ability (g-factor).
