Yes, allowing extra time for ADHD students is one of the most effective and widely used test accommodations. It helps reduce the pressure caused by distractibility, slower processing speed, and frequent task switching, key challenges for many students with ADHD during exams. With more time, students can work through tasks more calmly and carefully, improving both accuracy and confidence. 

That said, extra time for ADHD students works best when paired with the right exam strategies, such as time planning, break scheduling, and access to a quiet test environment. These combined supports can significantly improve academic performance over time.

How Extra Time Helps ADHD Students Succeed 

Here’s why extra time for ADHD students is often included in formal accommodations and how it supports exam performance. 

Reduces time-related anxiety  

Extra time gives students room to pause, refocus, and re-read questions. This helps manage stress and supports better test outcomes. 

Supports working memory and processing  

Students with ADHD may take longer to organise thoughts or recall information. Additional time reduces the risk of rushed or incomplete answers. 

Allows for breaks and pacing  

Structured pauses during tests can prevent burnout and support energy management. These exam strategies help maintain focus over longer periods. 

Improves fairness and academic performance 

 When used appropriately, extra time doesn’t give an unfair advantage. It simply allows students to show what they know under more accessible conditions, improving overall academic performance.
