School choice reimbursement

Every family in a failing public school system will be able to attend any school of their choice and seek reimbursement from their home district equal to the amount spent per pupil at that district. The condition for reimbursement is their student must meet or exceed the standardized academic achievement of their counterparts in the public school. Public school per pupil spending is a simple calculation of total budget/number of students. This reimbursement will be based solely on student achievement. Home schoolers can participate as well. Public schools will have to improve efficiently because if not, every year their cost per student increases it will create more competition for alternatives.
