Rina: I am getting concerned. My daughter is currently in a private special education school, paid by my school district, a 12:1:4. She is currently in the 2nd grade and is 8 years old. In August 2013 her IQ was a 83. The test used was Wechsler Preschool Intelligence test. In May 2014 when she was 6 years old I decided to have a neuropsychological evaluation done. The test that was used at the time was also the Wechsler Intelligence test, the 4th edition. Her IQ was a 85. Today as of February of 2016, her Full IQ is 63. I am shocked and in tears. The test that was used was Stanford-Binet-Intelligence Scale, 5th edition. I am not sure if her current placement is causing her IQ to drop. What test should I have done in addition to the school test? My daughter’s classification is Speech and Language delay, Auditory processing and executive function disorder. I am so upset.
