The twenty-second identification of labor ability is the grading of the degree of labor dysfunction and the degree of self handicap.

Labor dysfunction is divided into ten disability grades, the heaviest one and the lightest grade ten.

Barriers to self-care can be divided into three levels: life can not be taken care of at all, most of the life can not take care of themselves and part of life can not take care of themselves.

The standard of labor capacity appraisal shall be formulated by the labor and social security administrative department of the State Council in conjunction with the health administrative department of the State Council and other departments.
