On 15-19 April 2013, Sergei Kochetkov, Senior Interpreter from the Russian Interpretation Section at the UN Headquarters in New York, gave a series of master classes in the St Petersburg School of Conference Interpreting and Translation. During a week of intensive work the students brushed up their simultaneous interpretation skills doing actual speeches from the UN meetings in English and French. The classes with Sergei Kochetkov are a unique professional experience for the School trainees. Advice and analysis from such an experienced interpreter as Sergei Kochetkov will help the students acquire and apply UN standards of simultaneous interpretation.
