I believe that a child's speech and language should be assessed. Speech and Language are important when communicating with other children. Educators and parents should make sure that their children are at the appropriate level when it comes to their speech in order to move on to the next grade level. If a child is 4 years old and speaking like a 2 year old that could be an issue. If this happens I believe a speech therapist should be brought in to work with the child. If a child has delayed speech then most likely they don't understand much of what they are hearing either.
What ways are school aged children assessed in other parts of the world?
In Russia, elementary school last for 9 grades. After 9th grade they go to secondary school. At the end of the 9th grade children take a National Exam. Russian children go to school from ages 6 to 17. Classroom work often means reciting and being tested in a written form or orally by the teacher. Sometimes students are evaluated by the teacher in front of the class.
