Testing knowledge and testing intelligence are different. Intelligence can be tested through IQ test to evaluate the person’s cognitive and intellectual abilities such as, problem solving, abstract thinking, and understanding principles. In fact, a person’s knowledge that is related to a specific field or a course for example should be tested by using exams to evaluate the level of information gained.

Stanford-Binet IQ test is one of the most popular IQ tests. It is the original and first IQ test developed in 1916 by Lewis Terman at Stanford University and was based upon the earlier work of French psychologist Alfred Binet and his student Theodore Simon. This test was created to measure children intelligence.

It measures the cognitive intelligence based on five elements:

1-Visual-spatial processing

2-Quantitative reasoning

3-Fluid reasoning

4-Knowledge

5-Working memory

The advantages of Stanford-Binet IQ test:

1-Reliability: This means that the results are consistent over time, even if different evaluators administer the test or an individual takes the test on multiple occasions.

2-Validity: This means that scores on the test accurately reflect an individual’s cognitive abilities.

3-Providing detailed information.

The advantages of Stanford-Binet IQ test:

1-Language barriers and other cultural differences may also impact performance on the exam

2-Limitations to diagnose mental issues.

To sum up, based the difference between intelligence and knowledge, each one should be tested differently. Thus, a lot of IQ tests were created to measure the intelligence of people abilities. As a manner of fact, Stanford-Binet IQ test is a reliable test though its limitations and it has been used throughout the years to measure children cognitive intelligence.
