IQ Test 101

IQ tests can be used for a wide range of purposes including:

• Educational assessment and placement
• Assessment and diagnosis of intellectual disability
• Cognitive research
• Job candidate evaluation
• Assessing cognitive abilities including memory, speed, and attention

Modern intelligence tests often focus on abilities such as mathematical skills, memory, spatial perception, and language abilities.

The capacity to see relationships, solve problems, and remember information are important components of intelligence, so these are often the skills on which IQ tests focus.

Your IQ can have an impact on different areas of your life including school and work. High scores are often associated with higher achievement in school, while lower scores may be linked to some form of intellectual disability.
