Is it possible for a child to have adhd yet still have good grades in school?

Yes: Many adhd children are highly intelligent and with behavioral and medicinal assistance they can achieve their true potential. Evaluation by a recognized expert is essential for your child.

Yes, with supports: Optimal management of adhd, be it combined type or primarily inattentive type, is multimodal: medication + behavioral therapy (or coaching) + environmental manipulations. At school, this includes a legal " section 504" that modifies the rate, timing or amount of academic work & supports parent-teacher communication. See CHADD.org. Children who are academically gifted & talented can have adhd.

Sure: Grades are only one measure or outcome and imperfect at that - many bright adhd children power their way through early grades and may get good grades, but do so inefficiently - as demands increase in middle school or with increasedproductivity demands of high school or college, greater problems can emerge or while they succeed there may be more stress. Clinical evaluation is really the way to tell.

Yes: Attention is one of the important aspect in learning. Ability to associate, information base to draw those associations from etc are important. If the behavior, activity, impulsivity cause you to disrupt the general flow of work in the class you are more likely to be classified as attention deficit disorder. Only a thorough educational psychological evaluation can sort these things out.

Yes: ADHD is an impediment to school performance. Children who are very bright can perform well in school despite their ADHD.
