When a Child Scores Low Enough on the Stanford-Binet to Be

When a child scores low enough on the Stanford-Binet to be classified as mentally retarded, the test is repeated. A mother, whose child is asked to repeat the test at a later date, asks the nurse why her child has to go through this test a second time. Which of the following is the nurse's best response?

A) "We want to reduce the chance of human error and make certain we have interrater reliability in the scoring."
B) "Test-retest provides a chance for the rater to test the child's recall of information presented during the first test."
C) "A repeat test helps us give you a more accurate score, because many factors, such as mood or sleep, can influence the score."
D) "Your child scored low, and we want to give the child a second chance to prove that he has a normal intelligence quotient."
