The designation of ``Key School'' exists for selected schools at every educational level in China: elementary, secondary and higher. In addition, there are various levels of the ``key'' designation itself: There are national key institutions, provincial or municipal key institutions, and county or district key institutions. Key schools all enjoy priority funding as well as the privilege of recruiting the best students. At the elementary and secondary levels, this concept is similar to that of a ``magnet'' or ``college preparatory'' school in the United States. Entry into such schools is based on examination and academic promise and achievement. For such schools, success is usually measured in terms of the percentage of its graduates entering colleges and universities, especially the key colleges and universities. The philosophy has been that giving a limited number of schools, colleges and universities priority in allocating limited resources, then the training of the needed top-level manpower for China's reconstruction can be carried out more efficiently.
In certain areas, the concept of ``Key School'' has come under fire. Indeed, the success of the Key elementary and middle schools has too often been measured solely in terms of college placement of its students, rather than on more objective measurements of learning. Furthermore, remnants of the same sort of elitism that shut down the key schools during the Cultural Revolution have re-emerged, leading to questioning by the educational authorities.
