There are 120,000 teaching assistants in English schools. The government claim that teaching assistants are at the heart of its strategy for improving standards in schools.

The assistants supported weaker groups in the class while the teacher continued with the lesson. Despite the extra help, their results did not improve.
I didn't find the right solution from the internet.
