The normative sample used to develop a test has implications regarding the populations
- The normative sample used to develop a test has implications regarding the populations to which the normed scores can be generalized. Consider the following excerpt from the Mental Measurements Yearbook review of the Infant-Toddler Development Assessment:
There is no discussion of the types of children who represented the group used for development of both the Provence Profile and the complete IDA. Without such information, it is impossible to determine whether or not the IDA is representative along characteristics such as gender, family experience, and ethnicity. Without this information one could question the appropriateness of the IDA for all children.
When deciding whether a test may be appropriately used with a particular population, it is important to keep in mind the normative sample collected during the test’s development. Selective factors and other influences related to norming must be considered when implementing a test or scoring it.
To prepare for this Discussion, select one specific test instrument and a population. Research the test instrument you selected in the Walden Library, paying particular attention to the group used to develop or norm the instrument and considering how this may affect the populations with which the test is able to be used.

With these thoughts in mind:
Post the title and a brief description of the test and population you selected. Explain whether or not this test can be appropriately used with this population. Use current literature to support your response.
