What age group is the Leiter International Performance Scale designed for?

The Leiter International Performance Scale is designed for individuals aged 2 to 18 years. This assessment tool primarily evaluates non-verbal cognitive abilities, making it particularly useful for assessing children and adolescents who may have difficulties with traditional verbal assessments. It accommodates a wide age range to ensure that it can effectively measure developmental progress and intellectual capabilities in diverse populations, including those with special needs. By covering this age range, the Leiter allows for a comprehensive analysis of cognitive functioning as children grow and develop through different stages of life, taking into account varying developmental milestones. This flexibility makes it an essential resource for educators and specialists working in special education settings.
