Achievement Test Standardized Achievement Literacy 5

Question 1

On a standardized achievement test, 'differential item functioning' (DIF) analysis is conducted to:

Accepted Answer

Detect items that perform differently for subgroups of similar ability

Answer

DIF analysis flags items where students of equal ability but different group membership (e.g., gender, ethnicity) respond differently, suggesting potential bias.

Question 2

A district uses achievement test data to identify students who need reading intervention. This is an example of:

Accepted Answer

Formative use of standardized data to inform instruction

Answer

Using test results to identify students who need support and adjust instruction is a formative (instructionally oriented) use of data.

Question 3

A student's scaled score on a fall achievement test is 210; on the spring test it is 218. To determine whether this growth is meaningful, an educator should consult:

Accepted Answer

The test publisher's growth norms or conditional growth percentiles

Answer

Growth norms allow educators to evaluate whether observed score gains are typical, below typical, or above typical for students at that starting score level.

Question 4

Which factor MOST directly affects the difficulty level of an item on a standardized achievement test?

Accepted Answer

The proportion of students who answer the item correctly (p-value)

Answer

Item difficulty (p-value) is calculated as the proportion of test-takers who answered correctly; higher p-values indicate easier items.

Question 5

A test measures reading comprehension by having students read passages and answer questions. If the passages are too simple for the age group, scores will likely suffer from a:

Accepted Answer

Ceiling effect

Answer

A ceiling effect occurs when a test is too easy, causing many students to score at or near the maximum and preventing score differentiation.
