14 students have signed up to the course, which is too few to make it practical.
The Education Committee says that had this year's IB Diploma gone ahead, some classes would only have had one or two students in them.
It says this would have been an inefficient and ineffective use of staff.
The final decision was made by the political members of Education and Andrea Dudley-Owen is the committee president:
“The Committee found this a very challenging decision, not least because it feels too operational, but also because it is very supportive of the IBDP and the breadth of choice at Post 16.
"Pausing the programme allows school leaders to use resources more efficiently, and we are still proud to be able to maintain a very broad, creative and diverse curriculum offer to students through A Levels and IB Certificates, with every subject still available.”
The current intake of IB Diploma students are unaffected.
A consultation and assessment will be made ahead of the next school year with a view to generating more interest in the International Baccalaureate Diploma.
