Is it necessary for children to test calligraphy? Is there a national calligraphy grading institution in Shaanxi?

Hello, it's totally unnecessary. If you want to take the exam, you can consult a calligraphy teacher or ask the local book association. This is the significance of these ratings. The most important thing is to win the prize in the Calligraphy Competition of China Book Association, which will be useful for joining local book associations and national book associations in the future. Grade is not important, what matters is the seal of China Book Association on the award certificate. I hope it helps you.
