how to evaluate a kid without standard tests such as SAT/PSAT/SSAT

[eiholi]

^^ A particular test may not tell a lot about a kid but it helps us put a finger on his/her uniqueness as a human being. The other day I listened to a Radiolab podcast ( [listen here](http://www.radiolab.org/story/96056-your-future-marshmallow/) ) where a marshmallow test at age 4 may tell 200 points apart on SAT scores. They claim

put a kid in a room with a marshmallow, and tell her if she can resist eating it for 15 minutes, she can have 2 marshmallows. It turns out the kids who could wait were much more likely to be successful as adults.

So we have a lot to learn about our kids that some may say we won’t know and just wait and see. In reality predisposition of whatever or knowledge at a certain age may or may not weigh much in one’s life course.

Anyone knows other little tests that we can use to know our kids better?
