The result of SMASE-WECSA's SSC has been the consensus arrived at that INSET is an important component in the delivery of quality education to all. Consequently, all member countries recognize the need to institutionalize INSET in their policy and development strategies. Many member countries have set up technical teams to deal with issues relating to mathematics and science INSET. These teams are drawn from the over 1,500 personnel, who have benefited from capacity building programmes in Philippines, Malaysia or Kenya. In Kenya, there is evidence that SMASSE has improved performance in mathematics and science subjects over the last 5 years. As a result there is emerging confidence among SSC countries on the mutual benefits that arise from joint capacity building programmes like SMASSE.
