BCP Scoring Accuracy and Norms 3 — Questions and Answers
Question 1: A psychometrist calculates a Full Scale IQ of 103 using a 2020 normative sample. The test was originally normed in 2005. What phenomenon should be considered when interpreting this score?
- Regression to the mean
- The Flynn Effect (Correct answer)
- Standard error of the mean
- Cohort validity threat
Correct answer: The Flynn Effect
The Flynn Effect describes rising IQ scores over generations; using outdated norms inflates IQ scores because the current population performs better than the older norm group.
Question 2: On a standardized achievement test, a student's raw score is 35 but the ceiling is 40. The examiner notes many items near the ceiling were administered. What scoring concern does this raise?
- Floor effect making scores unreliable at the low end
- Ceiling effect limiting score differentiation at the high end (Correct answer)
- Basal error inflating the raw score
- Reverse scoring on terminal items
Correct answer: Ceiling effect limiting score differentiation at the high end
A ceiling effect occurs when a highly capable examinee approaches the top of the scale, reducing the test's ability to differentiate high ability levels.
Question 3: In which scenario is a grade-equivalent score potentially misleading?
- A third-grader earning a grade equivalent of 3.5
- A third-grader earning a grade equivalent of 7.2 (Correct answer)
- A student repeating a grade level
- A bilingual student tested in English
Correct answer: A third-grader earning a grade equivalent of 7.2
A grade equivalent of 7.2 for a third-grader does not mean the child performs like a seventh-grader on all material; it means only that the child's raw score equals the seventh-grade median on third-grade content.
Question 4: Which action should a psychometrist take if they discover a scoring error after submitting a report but before any placement decision is made?
- Discard the report and retest the examinee immediately
- Correct the error, document the change, and notify the referring professional (Correct answer)
- Keep the error private if the placement decision is unlikely to change
- Average the erroneous and corrected scores to reduce bias
Correct answer: Correct the error, document the change, and notify the referring professional
Ethical practice requires correcting errors, documenting the amendment, and communicating the correction to anyone who received the original report.
Question 5: A psychometrist is using tables that provide separate norms for males and females. What is the primary purpose of sex-separated norms?
- To rank examinees within their biological sex for fairer comparison (Correct answer)
- To reduce test bias by equating mean scores across groups
- To comply with federal testing regulations
- To enable gender-based quota selection in schools
Correct answer: To rank examinees within their biological sex for fairer comparison
Sex-separated norms allow comparison of an individual's performance to same-sex peers when meaningful differences exist in the construct being measured.
Question 6: A T-score has a mean of 50 and SD of 10. What T-score corresponds to one standard deviation above the mean?
- 55
- 60 (Correct answer)
- 65
- 70
Correct answer: 60
One SD above the mean on a T-score scale equals 50 + 10 = 60.
Question 7: When scoring a verbatim response on a vocabulary subtest, the psychometrist is unsure whether a child's answer earns 1 or 2 points. What is the correct procedure?
- Score conservatively and assign 1 point to avoid inflation
- Query the examinee using a standardized neutral prompt (Correct answer)
- Ask the examiner to re-administer the item after a delay
- Average 1 and 2 to assign 1.5 points
Correct answer: Query the examinee using a standardized neutral prompt
When a response is ambiguous, the psychometrist should use a standardized neutral query (e.g., 'Tell me more') as specified in the test manual to elicit a scorable response.
