testing Is there a less expensive way to get ADHD testing? The process of getting an ADHD diagnosis is a bit odd compared to other medical diagnoses. Some family physicians are comfortable diagnosing ADHD on their own (during a regular doctor's appointment), but many will send you to go get a more in-depth assessment with a psychologist OR will refer you to a psychiatrist. Similarly, some psychiatrists will give a diagnosis following a brief assessment during an appointment, but in particularly tough cases, will also send you to get a more in-depth evaluation from a psychologist/neuropsychologist. Another difficult aspect of ADHD diagnosis is that an appointment with a psychologist will usually cost money because it is not part of the public healthcare system. There are some psychologists within the public healthcare system that do ADHD assessments, but the waitlist is extremely long.
