By the end of the semester, if the child's goal achievement rate reaches 95%, we will say it is useful, and if the goal achievement rate is very low, we will say it is useless.

So you will find that the early education center promised that you would cultivate children's intelligence when you signed up for class. This abstract commitment can't evaluate the effect at all.

For example, the goal of kindergarten semester is to know 200 words, recite 10 stories, use scissors, know 8 origami steps, and walk smoothly across a 20 cm wide balance beam ... This is called a quantifiable goal.
