Child IQ Testing

Personalized Attention Fast Results Competitive Prices

Old Town Psychology offers the Wechsler Intelligence Scale for Children (WISC-V) for ages 6 - 16 years old and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) for ages 2 1/2 - 7 years old. These tests are the most proven and trusted cognitive measures available and both are accepted by public and private schools in Northern Virginia.

These assessments provide an overall IQ score and show you how your child compares to their peers. In addition, you will see how your child performs in a number of different areas, including verbal comprehension, visual spatial, working memory, fluid reasoning, and processing speed.

The fee for IQ testing is $295 and is due at the time of the testing session in the form of check, credit card, or cash.

What to Expect


I will schedule a phone call with you prior to the testing appointment to discuss your goals, your child’s needs, and logistics for the day of appointment.

This discussion allows me to better understand your child ahead of time so I can personalize the experience as well as answer any questions you may have.

I will also provide information on what you can expect and how to best prepare your child for the day of the test.


The IQ test is designed to be clinically rigorous, but that doesn't mean testing atmosphere has to be. I provide personalized attention to you and your child throughout the process with the goal of making the experience as comfortable as possible.

It’s normal for children to feel nervous when taking tests, so I take the time to build rapport with your child so that your child will feel comfortable taking the test.

The assessment is interactive and conducted one-on-one. This enables me to observe your child’s test-taking style and provide encouragement when necessary. I will also ensure that your child takes breaks when needed so that he or she doesn’t get tired and stays engaged. The testing session lasts approximately 90 to 120 minutes.


After the test is complete, I will schedule a separate appointment with you via phone or in person to go over the results and provide tailored feedback so that you can make the best-informed decision as a parent. You will receive a clear and objective report of the results that you can submit to the school.

In addition, I provide specific recommendations on what you can do to foster your child’s strengths and improve any areas of weakness. Recommendations are based on the most recent research and best practices in the field of education.

Parents report that the recommendations help their children enhance their cognitive abilities and progress academically.

What do IQ tests measure?

IQ tests provide an overall measure of an individual’s cognitive abilities. This means that the tests measure your ability to learn rather than how much you know about a specific topic. Often IQ tests also provides scores for different areas of cognitive functioning. For example, the Wechsler Intelligence Scale for Children (WISC-V) provides measures cognitive functioning in the areas of verbal comprehension, visual spatial, working memory, fluid reasoning, and processing speed.

What’s the average IQ score?

Tests like the Wechsler Intelligence Scale have an average score of 100. Ninety-five percent of the population have IQ scores that fall between 70 and 130. 

Can I improve my IQ score?

Yes. IQ scores are not set in stone and they fluctuate greatly during childhood and adolescence. IQ becomes more fixed with age, therefore, early intervention is especially important for improving cognitive abilities. Improving IQ isn’t so much about making people “smarter” but about using what you have more efficiently and effectively.
