population growth
The three-child policy may promote population growth and make the education system face greater challenges to accept more students.
educational resources
The three-child policy may aggravate the uneven distribution of educational resources, because some wealthy families may be more likely to provide better educational resources for their children, which may make it more difficult for children from poor families to obtain high-quality education.
Employment opportunities for women
The three-child policy may affect women's employment opportunities and career development, because some families may prefer to hire full-time nannies and family caregivers, which may make it more difficult for women to enter the workplace and get acceptable wages.
Student competition
The three-child policy may intensify the competition among students, because the number of students increases without the corresponding increase in educational resources and opportunities, which may lead to more students participating in more intense learning competition.
