The purpose of this study is to develop the "Organizational Health Scale" for employees and test its validity and reliability. The experimental form created for this purpose has been presented to the experts for their opinions. In line with the feedback from experts, exploratory factor analysis (EFA) has been conducted in a pilot study within a sample group of 50 people, and 1 item has been removed from the survey consisting of 29 items. The data obtained by 354 participants working in the health sector responding the 28-item test form have been analysed using the SPSS 20.0 and AMOS 24.0 software. In exploring factor analysis, a three-dimensional structure such as "career", "managerial ability" and "social psychology" have been reached. Together, these three factors explain 88.4% of the total variance. As a result of confirming factor analysis for scale, fit values have been obtained as RMSEA=0.055, CFI=0.926, TLI=0.925, GFI=0.901, AGFI=0.911, RMR=0.062 and the organizational health scale has been found to have good fit criteria. Cronbach's alpha reliability coefficients have been found to be 0.86 for the whole scale, 0.76 for the career sub-dimension, 0.80 for the managerial ability sub-dimension, and 0.64 for the social psychology sub-dimension, and the scale has been found to have internal consistency. The findings of the research have revealed that organizational health scale is a valid and reliable measuring tool. T Test, one-way variability analysis and Tukey Test have been carried out in order to determine if the organizational health levels of the participants are different in terms of demographic variables. As a result of the analysis carried out; it has been found out that there are significant differences between organizational health sub-dimensions according to the variables of gender, age, marital status, education, title, working time.
