Trondheim International School ("This") was founded in 2004 as an alternative to the Norwegian schools. It became an IB World School in 2008. It sees the IB program as a continuation process from the "PYP" to the "MYP" to the "DP" programs, and therefore has a continuation process with communication with the IB Diploma Program in the Trondheim Cathedral School.
