Thanks for posting your query.
I understand your concern as a vigilant parent but please do not label your child as ADHD
before a formal diagnosis is made.
Most children this age are mischievous , hyperactive and may not be attentive in class.
However In ADHD the behaviour is severe enough to disrupt normal life at home as well as school. Child may be inattentive in all tasks not just schoolwork , and the hyperactivity will be seen as child not able to sit still even for interesting activity/ play requiring focus.
In case you and the teachers do find the behaviour out of proportion then kindly approach a Pediatrician
or a Child psychologist
to get your childs diagnosis confirmed.
Wishing your child good health.
