This survey was conducted during the last part of the in-service course and sheds some light on how permutation and combination was taught in the Singapore schools after this topic was introduced into the syllabus. As the study was done only on a small group of participating teachers and that the sample was not random, the result of this study cannot be over generalised to the entire group of Singapore mathematics teachers. Further study is needed to have a more in-depth understanding on how combinatorics is taught in the Singapore secondary school setting. .
