The teacher is at the center of the three IB programs. During the candidacy stage (before authorization of a school as an IB World School, it is mandatory for the teachers to undergo the professional development training program that the IB offers to ensure high standards of teaching. For the authorized schools, yearly teacher development workshops are conducted for all the three programs where teachers from the IB authorized schools are supposed to undergo training.

The IB program has a clear focus on international education with content in an international context being covered in the curriculum. Students are also encouraged to think beyond what the curriculum states and to engage in community activities to further the all-round development of the student. Particularly at the diploma level, students are offered a variety of options (arts and science courses), thus offering flexibility.

Collaborative development of the schools is furthered by the IB through an online curriculum centre, which is a forum where schools and teachers share resources and discuss various academic matters. Worldwide conferences for the IB world schools are also conducted once in two years. The IB also offers recognition to schools that wish to form local associations for collaboration and development activities at the regional level.
