The primary purpose of this study is to explore the relationship between a latent variable “greening” and its measured indicators (i.e., rate of plantation, growing condition, type of plants, arrangement of plants and plantation management), and then to develop a greening evaluation form. We investigated 35 elementary schools and 172 junior high schools by means of field survey. Data were analyzed using Structural Equation Modeling (SEM) with LISREL 8.52. The findings based upon the analysis showed that the goodness of fit of the model was well (λ from 0.50 to 0.70, δ from 0.52 to 0.75, p-value=0.18, RMSEA=0.05, Standardized RMR=0.03, GFI=0.99, CFI=0.99, NNFI=0.98, ECVI< ECVI for Saturated and Independence Model). It suggests that the Greening Evaluation Form is available.
