Children can begin APD evaluations as early as 3.5 years old using age-appropriate testing protocols designed for young learners. A full hearing evaluation must be completed within the past six months before APD testing can proceed to rule out any peripheral hearing loss. Audiologists who specialize in APD use customized testing approaches based on each child's developmental level and reported listening challenges. Testing can continue throughout the lifespan, as APD can be diagnosed in adults as well, with audiologists selecting appropriate assessments for each age group.
