The principles of a good evaluation do not change with age: a clear question, multiple sources of information, validated tests, careful interpretation and a useful report. What changes is how those principles are carried out.
Who provides the information
For children, parents are primary informants, and teachers often complete rating scales because school is where many concerns show up. Teens contribute their own perspective more directly, and their self-report becomes an important part of the picture. Adults are usually the main informant about their own lives, sometimes with a partner or family member adding an outside view.
Which tests are used
Test batteries are matched to age. Child measures are built around play, pictures and developmentally appropriate tasks, and include academic achievement testing when school is part of the question. Adult batteries emphasize cognition, attention, memory, emotional functioning and, where relevant, work or academic demands. Every standardized test is scored against people of the same age, which is what makes the comparison meaningful.
How the day is structured
Young children need shorter sessions, more breaks and sometimes more than one visit. Teens and adults can usually complete more in a single day. At Amlea, every evaluation includes a built-in break and a 30-minute fNIRS session, and the CareTeam explains the schedule for your specific evaluation before the day.
What the report is for
Child and teen reports are often used with schools: 504 plans, IEP conversations and classroom supports. Adult reports are more often used for workplace or college accommodations, treatment planning with a therapist or physician, or clarity about long-standing questions. In every case, the report should answer the question that was asked in plain language and end with specific recommendations.
The question drives everything. "Is this ADHD, autism, a learning difference, or something else" is answered with different tools at different ages. Sharing your specific question when you book helps the clinician choose the right ones.
