Breakdown of Scores on an IQ Scale

• 1 to 24: Profound mental disability.
• 25 to 39: Severe mental disability.
• 40 to 54: Moderate mental disability.
• 55 to 69: Mild mental disability.

What is the mental age of a person with an IQ of 60?

An IQ of 60 typically falls into the mild intellectual disability range (IQ 50-69) and corresponds to a mental age for adults of roughly 9 to under 12 years old, meaning their cognitive skills are similar to an average 9-12 year old child, enabling them to learn basic academic skills and practical life skills but facing significant learning challenges. While the old formula (Mental Age / Chronological Age x 100) isn't used for adults, an IQ of 60 indicates cognitive functioning equivalent to a younger child, allowing for functional independence in daily life, work, and social relationships, although it's considered borderline or mild impairment.
