Through TNS Teleseker, we are able to evaluate our workshops externally. For us, this represents a reliable source where we can build on. TNS is one of the leading organizations regarding market research in Israel. For Matzmichim, they conduct telephone surveys with the teachers and educators of the particular schools where we were offered a workshop in the past months. In the survey of this year, 133 teachers were interviewed.  

The survey takes place 6 months after the conducted workshop in order to check the sustainable changes. So we can get an insight whether the teachers keep on working with our methods. The 6 months in between the workshop and the interview with the teachers quite ensure a distance to the experienced workshop and the long-term contribution of the workshop becomes obvious.
