Corruption is a critical issue in all types of organization: businesses, government bodies, state
enterprises, hospitals and universities in Thailand for a long time. Transparency International, the Global
Coalition Against Corruption conducted the survey on Corruption Perceptions Index to indicate the country
rank on how corrupt their public sectors were perceived to be during the year 2001 – 2012. The survey
during 2001 – 2011 used the scale of 0 to 10, where 0 meant the country was perceived to be highly
corrupted and 10 meant very clean from corruption. For the 2012 survey, the scale changed to 0 – 100,
where 0 represented the country which was perceived as highly corrupted and 100 represented very
clean from corruption. The ranking for Thailand from 2001 to 2012 has not improved (Table 1).
Corruption results in the loss to the organization and impacts the economy and country growth.
