ITA is an initiation and effort of NACC to measure good governance of the public agencies with evidence-based, perception and experience-based index and indicators. It is an important and constructive strategy to prevent corruption in the public agencies for Thailand.
The challenge is that the effort needs "time" and "many factor" to excel in measuring good governance in the task diversities of the public agencies. However, Thailand's NACC-ITA is a valuable measurement of corruption in accord with UNDP's Users' Guide to Measuring Corruption.
