How Does ADHD Combined Type Affect Academic Performance? 

ADHD Combined Type includes both inattentive and hyperactive-impulsive traits, which together can significantly impact how a student learns and behaves in educational settings. The effects on academic performance can vary depending on a student’s age, the support available, and the classroom environment. 

The Dual Impact on Learning and Behaviour 

Students with ADHD Combined Type often struggle with a variety of problems that impact their behaviour and ability to focus on class. 

Inattentive traits may lead to: 

• Missing instructions or forgetting key parts of tasks 

• Losing books, homework, or equipment 

• Difficulty maintaining focus during lessons or tests 

Hyperactive-impulsive traits might present as: 

• Blurting out answers before being asked 

• Struggling to remain seated during lessons 

• Interrupting teachers or peers unintentionally 

• Difficulty managing emotions 

For example, a child may start a worksheet but become distracted by background noise, then get up and begin talking to a classmate. While such behaviours are rarely deliberate, they can disrupt learning and negatively affect academic performance. 

Challenges Across Educational Stages 

Primary School 

In younger children, ADHD Combined Type often appears as distractibility, restlessness, and emotional outbursts. These pupils may find transitions between activities difficult and often need repeated reminders to stay on task or complete their work. 

Secondary School

 
As academic demands increase, problems with organisation, procrastination, and inconsistent work habits become more noticeable. Students may forget homework, misplace revision materials, or feel overwhelmed by managing multiple subjects. 

University/College 

University life poses its own challenges. Difficulties with long-form writing, time management and self-motivation can quickly lead to stress and lower grades. Even highly capable students may fall behind if they lack consistent routines or sufficient support. 

Supporting Academic Success 

Several strategies can help students with ADHD Combined Type succeed: 

• Use of visual timetables, timers, and clear step-by-step instructions 

• Strategic seating to reduce distractions 

• Extra time in exams or breaking assignments into manageable parts 

• Access to ADHD coaching or therapy to strengthen executive function 

• Medication, if recommended by a clinician, alongside consistent emotional encouragement 

Where appropriate, families in the UK can apply for an Education, Health and Care Plan (EHCP) to formally define a student’s support needs.
