Survey collectors and supervisors will be trained to improve the quality of data collected and additional equipment such as computers and servers will upgrade the current database system. Faculty research capacity will be strengthened. For this next phase, HSPH plans to design and implement a public health intervention focusing on adolescent health and also enhance dialogue with stakeholders and local authorities. These communications activities would be pursued through workshops, seminars, and monthly meetings.
