What is IQ and how is it measured?
IQ (Intelligence Quotient) is a standardized score used to assess human intelligence. It's calculated by comparing your test performance to the average performance of people in your age group. The standard IQ scale uses 100 as the average, with 15 points representing one standard deviation. This means about 68% of people score between 85 and 115.
What type of IQ test is this?
IQ Spark uses Raven's Progressive Matrices, a non-verbal test that measures abstract reasoning ability. The test consists of visual geometric patterns with a missing piece, and you must identify the correct piece from multiple options. This type of test specifically measures "fluid intelligence" – your ability to solve new problems and identify patterns.
How accurate is this online IQ test?
While IQ Spark is based on the scientifically validated Raven's Progressive Matrices methodology, online tests have limitations compared to professionally administered tests. Factors like testing environment, fatigue, and technical issues can affect results. For official purposes (education, employment, clinical assessment), we recommend consulting a licensed psychologist for a comprehensive evaluation.
How long does the test take?
The test has a 20-minute time limit for 36 questions. Most people complete it in 15-20 minutes. The time limit is designed to add a reasonable challenge while still allowing enough time to thoughtfully consider each question.
Can I retake the test?
Yes, you can retake the test as many times as you like. However, practice effects may increase your score on subsequent attempts. For the most accurate assessment, we recommend waiting at least 2-4 weeks between attempts.
What do the IQ score categories mean?
IQ scores are typically categorized as follows:
- 130+: Very Superior (top 2%)
- 120-129: Superior (top 9%)
- 110-119: High Average (top 25%)
- 90-109: Average (50%)
- 80-89: Low Average
- 70-79: Borderline
- Below 70: Extremely Low
Why does the test adjust for age?
Fluid intelligence (the type measured by pattern recognition tests) naturally changes throughout life. It typically peaks in early adulthood and gradually declines with age. Our age adjustment accounts for this, ensuring that your score reflects your cognitive ability relative to others in your age group.
Is my personal data secure?
Yes. IQ Spark does not store any personal data on servers. Your test responses and results are processed entirely in your web browser and are not transmitted or saved anywhere. We only use anonymous analytics to improve our service.
Can IQ be improved?
While your baseline cognitive ability is largely genetic, research suggests that certain activities can help maintain and potentially improve cognitive function. These include regular mental challenges (puzzles, learning new skills), physical exercise, adequate sleep, and a healthy diet. However, claims of dramatically "increasing IQ" should be viewed skeptically.
Why are there no language-based questions?
IQ Spark deliberately uses non-verbal pattern recognition questions to make the test "culture-fair" – meaning your score isn't affected by your language skills, educational background, or cultural knowledge. This type of test is considered one of the purest measures of innate reasoning ability.
