The objective of this research was aimed to investigate the environmental problems of an unhygienic school in order for them to apply participation strategies for Buddhist novices to hygienically improve their school; both before and after the application of the participation strategies. This research population was 426 Buddhist novices, 4 laymen and 6 monk teachers. The first sample group of 206 Buddhist novices was randomly selected for an evaluation of surrounding satisfaction. The second sample group was 24 Buddhist novices studying in grade 11 and meeting the qualification  for the development and participation of a hygienic school environment. 
	The research procedure comprised the study of common problems, collection of opinion and suggestions for a solution, finding development strategy for hygienic environment, and strategy application and assessment. The research instrument was a questionnaire regarding the novice satisfaction towards their school environment and the development guideline for hygienic environment of the school. The data analysis was conducted through percentage, mean and, standard deviation.  
	The finding revealed that the common problems were insecurity, landscape, and unhygienic standards. After the participation creation and hygienic environmental development, the novices satisfaction towards their school environment was at a high level. To promote this participation strategy a project was co-developed called 5S (promotion project with five hygienic steps). It showed that the school environment became more hygienic after its adoption; the novices satisfaction increased from 2.05 to 3.89.
