The purpose of this research is to find out: 1) the strategy of Islamic boarding schools in building the substantive competence of students in preaching, 2) the strategy of Islamic boarding schools in building the methodological competence of students in preaching. To find out how the results of this research were carried out with descriptive qualitative research with data collection techniques through interviews, observation and documentation. From the results of this study, it can be concluded that the strategy of Islamic boarding schools in building the substantive competence of students in preaching includes coaching that leads to strengthening Islamic values, so that these Islamic values will be seen from their breadth of knowledge and morals. While the development of the methodological competence of students in preaching includes building the abilities that exist in students in preaching, so that they are able to make good da'wah plans, as well as being able to carry out these plans and master the capability of da'wah.

The use of methods is very important in obtaining the success of any process, the better the method used, the more effective the process is in achieving the desired goal. In da'wah activities, method is important to achieve the goals of da'wah. Talking about the da'wah method, it is very identical to the da'wah method in surah an-nahl verse 125, namely the method of bil hikmah, mau’izhah and Mujadalah. If we examine this da'wah method in the perspective of empowerment, it will be found a match between the da'wah method in Surah an-nahl verse 125 with the empowerment method in general. Da'wah with empowerment has similarities in its activities, they both carry out the process of releasing themselves for the community or their mad'u from bad conditions to better conditions, and in the end they become independent and able to overcome their problems independently.
