Ugh, two year checks.
I’ve done hundreds of the things and they are always a source of upset for parents! Almost regardless of the content tbh.
The criteria is tricky and different professionals approach the same areas of development slightly differently. Personally I think this is due to personal approach mixed in with the vagueness of the EYFS guidelines on checks.
It is also so important to remember that, as a professional, we can only score based on what we actually see.
So, for example, imagine I am assessing a child on their fine motor skills by watching them using a pencil to draw. They pick up the pencil, but drop it. I encourage them to try again, but they become distracted and walk away. This happens on a few occasions.
Now, I’ve seen them pick up the pencil but not actually use it. I believe that they could based on their understanding, grip, etc but I haven’t actually seen it. You may tell me that he draws all the time at home. But I haven’t seen it. Therefore, I can’t put down that they are secure in this skill. If I see it once or twice, I can still only put emerging or developing, because I haven’t seen it regularly. They can do it, but that isn’t reflected in the language of the assessment.
I’ve very much oversimplified it there, but I hope you see what I mean!
