Applying an efficient method for studying and assessing school learning space is a considerable issue in Iran country so the main purpose of this research was to introduce a scale utilizing CFA models. The mixed method was used for extracting architectural variables of the learning environment, via a survey study by distributing the "six factor school building checklist" consisting of six sub-constructs among the sample of 180 accessible volunteer girl students in Gorgan city ( academic year 1397-98). The qualitative study was performed by coding technique to extract some repeated factors for enhancing student achievements from recent research (2017-2022), which includes the effects of green spaces, flexible spaces, daylight, seating arrangement, window view, and outdoor education. According to the quantitative part of current study, all the six factors can describe the "six factor school building checklist" and the model fit was achieved and reported as a very good model fit according to CFI (0.93) and RMSEA (0.045) indexes. The factors hierarchically, social space, interface, massing, way finding, context and finally comfort can determine and describe the main scale. Thirty- three variables among Thirty-eight, can describe the main construct. From the social space factor; the ease of accessibility to the teachers' office, from the interface; students' spatial experience from the main entrance to the classroom, from the massing; variation in the massing for providing interest, from the way finding factor; easily understood circulation for interior routes and finally controlling the destructive noise level from the comfort factor reported with the highest factor loadings.
