The SON-test in Kenya
Since last year the development of a new version of the SON-R 5.5-17 has started.
With this new version the pictorial materials will be modernised while the aim is to make the test less sensitive for cultural differences. With this adaptation, research that has been conducted with the SON-R 5.5-17 in Brazil, China and Peru will be used.
Preliminary research with the changed test-materials is now taking place in the Netherlands, Brazil, Kenya and Morocco.

The photographs have been taken during research that was done by two students of the University of Groningen, Heleanne Rusthoven and Geerte Boven, in March 2004, in Nakuru, Kenya.
This research was conducted in cooperation with the department of education of the Nakuru city council and took place at two schools in the city of Nakuru and at a rural school.
