The training institution is Party A, and the parents are Party B ... This is because the training institution is the party providing services and is responsible for providing education and training services, while the parents are the party receiving services and need to pay training fees and accept the services of the training institution. In the contract, the identity of both parties is very important, which determines the rights and obligations of both parties. As Party A, the training institution has the obligation to provide high-quality education and training services for parents and protect their rights and interests; As Party B, parents need to pay training fees on time, actively participate in children's education and training, and cooperate with training institutions.
