1.
What are the attributes of a test that produces valid scores?
example:
The test covers relevant content.
The test relates to external criteria, such as a blueprint or table or specifications.
The test measures what it intended to measure.
2.
Why is test validation a continual concern?
example:
High stakes decisions may be made based on test results and the content, construct, or criteria for the items may change.
There is always more evidence that can be gathered
3.
What are the three traditional sources of evidence for the validity of a test?
example:
Content-related evidence, criterion-related evidence, construct-related evidence.
4.
Provide 3 examples of unintended, negative effects of testing, interpretation, and subsequent action taken on the population being tested.
example:
A teacher gives a test to a group of students to separate them into beginning, average, and advanced groups. The teacher retests them a year later. Due to low self-esteem, the beginning group shows little progress.
A teacher gives a test to a homogeneous group of students and then tries to generalize to a heterogeneous population.
A teacher teaches directly to the test and not the designed curriculum.
