5 yr old normal behaviour or something else?

My son is 5 yrs old in SK. Teacher and I had a meeting yesterday she thinks my son has ADHD and provided a list for why she thinks this. To me it sounds like a 5 yr old behaviour. She provided me with a letter to give his dr to have his evaluated. Below are the key points. I don't know what to do? Or how to deal with this. Any advice pls! Would appreciate it :) Struggles with attentive listening during group learning (lies down, feet on the wall, roles around, in others personal space, chatting, zones out) Struggles with focusing when educator is talking to him one-on-one. He fidgets with hands/fingers, needs reminders to make eye contact, constantly moving his body Distracted during small group table activities - fidgeting in his chair, getting up and walking around, pushes chair back to balance on the back two legs, tapping pencil, Blurting answers to questions rather than raising his hand Some difficulty with emotional regulation - Can get upset when a peer doesn't follow his plan or idea for play by grabbing/tossing materials or ruining creation Struggles with following transition routines like getting ready for outside/end of day by zoning out, fidgeting with belongings or chatting with others. Rushing through his work to get to a preferred task (exploration/play) Struggles with using an indoor voice, walking feet and cleaning up materials.
