Many students do well in courses where they have an especially strong interest, but perform poorly in other courses required in their program because they may not be able to sustain their attention long enough to put in the effort. Many people have struggled with some symptoms of inattention and related difficulties since childhood, but may not have considered the possibility of ADHD until they've reached a point where their functioning is significantly impaired at some point in their adult years.

An assessment can help determine if ADHD is a condition interfering with your success. This evaluation will clarify your cognitive strengths and needs, executive functioning (e.g., organization, sustained attention, regulation of alertness, etc), and will evaluate for possible conditions such as learning disabilities which frequently co-occur. 

The end result of an assessment is a formal report containing your test results, diagnostic impressions, and relevant recommendations that informs a plan to improve your functioning and help you achieve your goals. If an assessment indicates the presence of ADHD and/or a learning disability, then strategies and accommodations can be formally identified that can help reduce barriers to your success in post-secondary or help you advocate for reasonable accommodations in your workplace.
