Describe how reliability was established	1. Content Sampling: Coefficient Alpha: Chose 6 age intervals Alternate Forms: Both forms were given during one session. Correlation between the two forms is a reliability index 2. Time Sampling: Test-retest 2 groups: 33 children (ages 2-4) from TX 83 (ages 5-7); 50 from SD, 33 from TX 3. Interscorer Given by two graduate students in Special Education from TX. Given to children ages 5-7. 51% Female; 49% Male.

Describe a situation for which it would be chosen over the other tests	An appropriate situation in which to use this test would be when assessing a child who appears to be behind the other children in his age group and/or in his class in his language skills. This test would help to determine whether or not a child could benefit from an early intervention program.
Describe a situation for which it should not be chosen over the other tests.	You would not use the test when assessing the strengths and weaknesses of a group of children.
