The new "Non-Governmental Education Promotion Law" established the classified management system of profit-oriented and non-profit-oriented private schools and confirmed it as the basic framework and orientation of legislation. To scientific design for-profit and non-profit school drop-out mechanisms, we defined the basic connotation of the exit mechanism of the private school. Hence, the conclusion obtained is that two occasions will appear, respectively withdrawal of private education due to "crisis" and because of "business opportunity". So we improve some suggestions on improving domestic private schools' withdrawal mechanism. For the non-profit private schools of the withdrawal mechanism, we should establish a risk alert mechanism, withdrawal property rights mechanism and stakeholder protection mechanisms. For profit-oriented private schools' withdrawal mechanism, the author holds the idea that the following can be concentrated on based on referring to "Company Law" and "Bankruptcy Law": construct property circulation mechanism based on efficiency, the third Party's assessment mechanism based on justice and withdrawal supervision mechanism based on order.
