Steve is one of cApStAn’s founders. He received his education in English, Dutch, French and German but he is essentially an autodidact and a field practitioner. In 1998, Steve was sought out to organise the translation verification of PISA 2000 instruments and, since cApStAn’s creation in 2000, Steve has supervised linguistic quality assurance in PISA and in over 35 international surveys and polls. His translatability assessment methodology is applied in small and large multilingual projects in both the private and the public sector. Steve is the driving force behind cApStAn’s adaptive strategy.
