The introduction of choice will stimulate better performance in every school institution through competition. If the school does not perform well the students will tend to select institutions where they are performing at a higher level.
1) Parents and children will be able to select schools that align better with their learning style. Not all people learn best the same way. Schools that offer alternatives that are needed, will succeed, while those that do not will have to alter their methods in order to get students to enroll. This market system is a reality in the higher education arena in the US today. Universities are expanding to accommodate the needs of potential students everywhere.
2) If parents want their children to receive social and moral teaching that aligns with what a school is teaching, they will be able to send their children there. If, however, they are unhappy with the philosophy of the school, they can enroll elsewhere. This will have a balancing effect on the administration that is not possible when choice is restricted.
3) Security and safety will be impacted by school choice because the institutions will all be more sensitive to the students and families who pay the bills, rather than to a bureaucrat who has no direct personal concern for the individuals. However this issue requires more than just the school choice solution. Schools need to be funded to enhance security, including but not restricted to facilities enhancement and policing.
