Intelligence can generally be defined as a person's ability to think, perceive, solve problems, and manage these abilities. Intelligence tests are performance-based tests that aim to measure functions in different areas of the individual's brain and identify an individual's strengths and weaknesses. These tests are administered to identify different brain functions and which areas are stronger or weaker. There are many different intelligence tests available worldwide and in Türkiye. However, the three most commonly used intelligence tests in Türkiye are:

• WISC-R: A test used to measure intelligence in children. Widely used in Turkey, the WISC-R was designed to assess children's cognitive abilities.
• WISC-R 4: Another test used to measure intelligence in children. The WISC-R 4 is an internationally validated test for understanding and assessing children's cognitive abilities.
• Stanford-Binet: Another important test used to measure intelligence. The internationally reliable Stanford-Binet test is used to assess individuals' cognitive abilities and is the preferred test in some clinical studies in Turkey.

These tests are used to determine an individual's cognitive abilities and strengths/weaknesses. These tests are frequently used in clinical studies in Türkiye because they are internationally validated and have been adapted for Turkey.

When conducting intelligence tests, it's crucial to ensure a quiet environment and a setting that won't distract the child. Intelligence tests can be administered both individually and in groups. Individual intelligence tests are tests where the examiner and the child sit face-to-face and proceed in a question-and-answer format. The examiner directs the child through the test questions one-on-one and evaluates the child's responses.

Group intelligence tests, on the other hand, are administered to groups of several individuals. In these tests, group members take the tests individually, but they also complete them together in the same environment. Each individual takes their own test independently. In this case, the test results are evaluated based on each individual's performance.

Both administration methods offer distinct advantages. While individual tests assess an individual's individual performance, group tests may be more likely to measure intelligence and cooperation abilities in a diverse environment. The choice of test type depends on the purpose of the test and the characteristics of the individuals being tested.

In What Situations Should Intelligence Tests Be Performed?

Intelligence tests are used to assess children's cognitive abilities, mental development, and learning capacity. These tests are used to identify children's strengths and weaknesses, identify learning difficulties or special abilities, and understand their educational and support needs.

Intelligence tests can be used particularly in the following situations:

• In children with learning difficulties: If a child is thought to have learning difficulties at school or in daily life, intelligence testing can be used to understand the causes of this situation and support the learning process.
• In children with behavioral or emotional problems: When behavioral or emotional problems such as hyperactivity, introversion, and fear of school are observed, intelligence tests can be a tool to understand the child's cognitive status.
• For children who need special education: Intelligence tests can be an important resource for understanding the learning profiles of children who need special education and preparing appropriate educational programs for them.
• For gifted or talented children: Intelligence tests can be used to identify the strengths of gifted children and develop a personalized educational plan for them.

These tests are a tool for understanding a child's cognitive abilities and are typically administered by a clinical psychologist, educational specialist, or pedagogue. By highlighting a child's strengths and identifying their weaknesses, the test results can guide families and educators to support their children more effectively.

How Should Intelligence Test Results Be Interpreted?

When interpreting intelligence test results, a child's scores are often compared to those of other children in a specific age group. This comparison is used to understand how a child's intelligence test performance compares to their age. Furthermore, intelligence tests can assess not only intelligence level but also performance in various areas, such as learning disabilities, attention deficits, motor skills, and other abilities.

Intelligence test results are often expressed as standard scores or percentiles. Standard scores indicate where a child's performance on the test ranks relative to their age. For example, a standard score of 100 indicates that the child is performing on par with other children in their age group, while a standard score of 85 indicates that the child is performing below other children in their age group.

In addition to intelligence tests, additional tests can be used to assess a child's performance in areas such as attention, hyperactivity, learning disabilities, and motor skills. These additional tests allow for a more comprehensive examination of a child's cognitive and behavioral abilities.

The results of these tests are used to understand a child's strengths and weaknesses, identify educational and support needs, develop specialized education programs, and guide families to support their children more effectively. However, test results alone may not fully reflect a child's full potential or abilities, so interpretation and evaluation of the results should be done carefully by professionals.

What are the Types of Intelligence Tests?

Among the reliable intelligence tests used in our country, some stand out:

Wechsler Intelligence Scale for Children IV (WISC-IV) : This test is used to assess the cognitive abilities of children and adolescents. It includes scales to determine the intelligence levels, strengths, and weaknesses of children ages 6 to 16. It evaluates general intelligence, attention, concentration, memory, and problem-solving abilities through verbal and performance tests.

Stanford-Binet Test : This test is used to determine the intelligence levels of children between the ages of 2 and 6. It assesses fine motor skills, visual and auditory memory, reasoning abilities, and language skills. It compares a child's mental development across different areas and reveals their performance.

Leiter International Performance Test : This test is used to assess the intellectual abilities of children with hearing or speech impairments. It is a performance test that does not require language skills and is administered to individuals aged 2 to 18. It measures visual learning and problem-solving skills to assess intelligence.

These tests are administered to determine children's mental abilities and explore their strengths and positive aspects. Each test includes scales for different age groups and characteristics and is evaluated by experts. Test results are used to guide the child's educational and developmental process.

What is Checked in an Intelligence Test?

Intelligence tests consist of measurements taken to assess a person's cognitive abilities. These tests are typically administered to children, adolescents, or adults. Intelligence tests assess various skills and areas:

• Verbal abilities: Verbal abilities such as vocabulary, word comprehension, grammar, logical thinking and general knowledge are assessed.
• Performance abilities: Performance abilities are measured in areas such as picture completion, organization, visual-spatial skills, and mathematical thinking.
• Memory: Short-term and long-term memory, auditory and visual memory abilities are tested.
• Logical thinking and problem solving: Understanding logical sequences, analytical thinking abilities, problem solving strategies and reasoning skills are assessed.
• Attention and concentration: Cognitive processes such as focus, attention span and concentration are measured.

Intelligence tests are typically administered using standardized methods and compared with age-appropriate normative data. These tests are used to identify a person's strengths and weaknesses and provide guidance for educational, therapeutic, or developmental purposes.

What Questions Are Asked in an Intelligence Test?

Intelligence tests typically include questions from a variety of categories, including multiple choice questions, puzzles, mathematical problems, and logical thinking questions. These tests aim to measure a person's general intellectual abilities, verbal and numerical abilities, problem-solving abilities, and logical thinking abilities.

For example, intelligence tests such as the Wechsler Intelligence Scale for Children IV (WISC-IV) may include questions across a variety of categories to measure vocabulary, logical reasoning, abstract thinking, numerical skills, and visual-spatial abilities. These questions are intended to assess problem-solving skills, reasoning abilities, and general intelligence.

Other tests, such as the Stanford-Binet Intelligence Test, may include questions of varying difficulty levels based on a child's developmental level. They may include different types of questions, specifically to measure verbal skills, memory abilities, logical thinking skills, and visual-spatial abilities.

It's important to remember that each intelligence test includes questions in specific categories and aims to measure different areas of intelligence. Therefore, the content and questions of intelligence tests can vary from test to test.

At What Age Should a Child Take an Intelligence Test?

Intelligence tests are generally administered to children ages 6 and older. However, in some special circumstances or for certain tests, intelligence tests can be administered at earlier ages. For example, non-linguistic intelligence tests, such as the Leiter International Performance Test, can be administered to children as young as 2 years old.

How Many Hours Does an Intelligence Test Take?

The length of intelligence tests can vary depending on the type of test, its scope, and the child's ability to perform the test. Intelligence tests typically last several hours. For example, comprehensive intelligence tests, such as the Wechsler Intelligence Scale for Children (WISC), can take several hours to complete, depending on the child's responses and the sectional differences.

However, the testing duration may vary depending on the child's attention span, concentration, and overall engagement level. In some cases, the test can be administered in multiple sessions to prevent fatigue and improve performance. Experts typically determine the duration based on the scope of the test and the child's condition, and plan the most appropriate testing time based on the child's needs.
