An IQ Score 75 is Borderline Intelligence

The Wechsler Intelligence Scale classifies an IQ Score of 75 as borderline intelligence which is also considered to be borderline mental retardation.

If your child has scored 75 on an IQ test previously, there are several reasons why your child scored so low. It's possible that your child may have a learning disability such as dyslexia or Attention Deficit Disorder (ADD) or may suffer from an anxiety disorder or perhaps even borderline mental retardation.

To help rule out learning disabilities, we suggest that your child take the Spatial ISIQ Childrens IQ Test. This test is recommended for children ages 6 – 16.

Intended Use: The Spatial ISIQ Childrens IQ Test is intended as a test that parents of young children and teenagers can use over the Internet for measuring spatial intelligence. Scores obtained can help persons with self-awareness, self-understanding and making plans for schooling and/or career choices. Reports can be used by professionals as well, as in assessing for career planning, school placement and problem diagnosis. For example, when diagnosing ADHD, learning disabilities and dyslexia, it is important to rule out mental retardation.

If your child takes the test and scores between 67 – 85 there is a chance that your child has borderline mental retardation. Furthermore, you should consult with a school counselor about obtaining a proper diagnosis, (that is if it is during a school year) or you should seek consultation from an experienced licensed clinical psychologist. Moreover, you will be provided with a detailed analysis obtained from taking the Spatial ISIQ Childrens IQ Test which you can present to a counselor or a clinical psychologist should you seek professional help.

Over 99 percent of online IQ tests are created by non-licensed psychologists or clinicians, and therefore should not be taken seriously or should not be taken at all! Scores obtained from these so-called IQ tests are often erroneous and/or superficial. In light of this knowledge, you can trust that The Spatial ISIQ Childrens IQ Test was created by William A. McConochie, Ph.D who is a practicing psychologist who has authored several diagnostic tests and has specialized in test development and diagnostic evaluations from 1986 - present.

GRE and SAT scores can also be converted from an IQ score of 75. Finally, the IQ table gives you the rarity and percentile of your IQ score and it also demonstrates how your IQ score ranks against the general population.
