An online ADHD assessment typically costs $150 to $900, depending on the service provider and whether the package includes a full diagnostic evaluation or just a quick screening [1][2].
For a specific and widely cited option, ADHD Online charges a flat $189 for its initial "Mentavi Smart Assessment," which is a comprehensive questionnaire reviewed by a licensed psychologist [1]. This is significantly cheaper than in-person evaluations, which can cost upwards of $1,000 to $5,000 out-of-pocket [1][2].
Here is a breakdown of typical costs:
- Quick Online Screening: $150 – $300 (Fast and accessible, but may not be accepted for formal accommodations like school or work) [2][3].
- Comprehensive Online Diagnosis: $189 – $500 (Includes detailed questionnaires and professional review, often accepted by physicians) [1][2].
- In-Person Evaluation: $1,500 – $5,000+ (Most comprehensive, involving 6–10 hours of testing, but very expensive) [3][5].
Recommendation: If you are looking for a cost-effective and physician-accepted option, consider ADHD Online at $189 for its full assessment [1]. For those needing a free initial check before paying, Mental Health America offers a free, scientifically validated online ADHD test [9].
