What are the best motor tests, to be carried out in childhood, to assess fine motor skills, gross motor skills, balance, agility, strength, endurance and flexibility in large-sample studies (or to be used widely in schools)? I'm creating and testing my list, but sharing ideas should be better, as usual.
The requirements shall be: feasibility, cheapness (or even better gratuitousness), validity.
I know it is a big, but really useful, topic.
Any feedback would be appreciated
