About Us

YNS is a non-profit organization that focuses in capacity building and research activities connected to issues of good governance and education, particularly in the Indonesian regional development sector. Since its establishment in 1999, YNS has been actively undertaking strategic policy research and creative development activities.
As an independent organization, YNS may directly provide a knowledge-based approach to parts of regional development, particularly aspects of human development as the primary foundation for regional development.
Human development is inextricably linked to the implementation of good governance. Human development will stimulate and improve good governance through the existence of a good education sector. Moreover good educational programs will not function efficiently and substantially without good governance. As a result, in the last 5 years, YNS has begun to focus on the education sector.

Edy Jitro Sihombing M.Pd
After attending trainings held by YNS, I implemented the print awareness to the 1st grade students. Awesome, they became aware of the use of punctuation marks. Likewise in reading, although they have not been able to read one sentence yet, they could read word by word, distinguish letters, syllables, words, and also sentences. Excellent, thanks.
