At my son's school there is first a meeting with parents and others, then follow up evaluation if everyone agrees. The parents have to give consent first. I wish his K teacher had recommended it. Now in 4th grade his problems are much worse and we're finally getting evaluations done. I go tomorrow to get the outcome and see where to go from there. He didn't really struggle academically until 2nd grade but had all of the issues you mentioned. Not trying to scare you but at that young age it's much easier to help a child before they fall way behind and start to really feel the effects emotionally. Of course it's up to you. I'm just adding my experience.
