Aims: Understanding the components and analyzing the relationships among the various components of the teaching quality from the professors’ view point can help better analyzing of teaching quality. This study aimed to analyze the relationship between the factors influencing the teaching quality of teachers' attitudes using structural equation modeling.

Methods: This cross-sectional study was done in 2013. 396 professors and faculty members were elected from Medical Sciences University of Tehran selected by simple random sampling method. Siraj teaching quality questionnaire was used to measure teaching quality. Data analyzed by the Lisrel 8.8 software. To evaluate the models’ fitting, the GFI, AGFI, RMSEA parameters and Chi-square test were used.

Findings: Interpersonal relations component showed the greatest effect to improve the quality of teaching. The highest factor loading of the lesson plans component was with teaching component (0.11), the highest factor loading of teaching component was with teaching component method (0.34) and the highest loading factor of teaching evaluation component was with teaching component (0.34) and the loading factor of interpersonal relations component the highest factor loading was associated with teaching evaluation component (0.36). Also, regarding RMSEA, AFGI and GFI, the structural relationship analysis modeling had a good fitting among the components of teaching quality.

Conclusion: Interpersonal relation component is the most important component among the other teaching quality components and structural equation modeling show that the relationship between various factors and their interaction should be appropriately identified.
