BCP Scoring Accuracy and Norms 2

Question 1

A psychometrist scores a 10-subtest battery and finds the sum of scaled scores is 87. What is the next step before converting to a composite score?

Accepted Answer

Verify the sum matches the test record form's prorating rules

Answer

Before converting subtest sums to composite scores, the psychometrist must verify the sum is complete and consistent with any prorating rules specified in the manual.

Question 2

Which type of norm group is most appropriate when evaluating a 7-year-old child's reading performance for diagnostic purposes?

Accepted Answer

National age norms

Answer

National age norms provide a standardized comparison to same-aged peers, which is most appropriate for diagnostic evaluation of a child.

Question 3

A raw score of 42 corresponds to a percentile rank of 84 in the norm table. What does this mean?

Accepted Answer

The examinee scored higher than 84% of the normative sample

Answer

A percentile rank of 84 means the examinee scored equal to or higher than 84% of individuals in the normative sample.

Question 4

When a normative table provides interpolated values between listed raw scores, what is the psychometrist doing when selecting the correct row?

Accepted Answer

Using the exact row corresponding to the obtained raw score

Answer

The psychometrist selects the row that exactly matches the obtained raw score; interpolation is already built into published norm tables.

Question 5

An examiner mistakenly awards full credit on an item that should have received partial credit. What scoring error category does this represent?

Accepted Answer

Commission error — over-crediting

Answer

Awarding more credit than warranted is a commission error, specifically over-crediting, which inflates the obtained score.
