Based on the information on the websites of the discipline inspection and supervision committees of 31 provinces （cities，districts），this paper evaluates the information disclosure work of the Provincial Discipline Inspection and Supervision organs. In current stage，the construction and openness of Provincial Discipline Inspection and Supervision organs’ platform turn out relatively sound and perfect，and the information disclosure of structural organizations is generally similar，with relatively comprehensive departmental budget and final accounts，concrete information on personnel and staff，timely and comprehensive work reports of the plenary session of the Discipline Inspection Commission. The information disclosure of inspection work and its process are more standardized in order，with powerful and effective information of “Notification exposure”，and the wider participation in supervision. However，some problems on information disclosure could be noted on the following aspects，including incomplete organizational structure，inadequate information on department revenue and expenditure，and insufficient，information on the construction of social participation and interaction channels. It is suggested to comprehensively strengthen the website construction，systematically enhance the transparency of the information disclosure，continuously strengthen the notification and exposure，and deepen and broaden the interaction and exchange.
