After repeated experiments, reliability and validity analysis and factor analysis was applied to draft scale at the beginning, scale was consist of 25 items as a standart scale. Results: Scale items was grouped in seven factors and reliability coefficients of these subscales was between 0.53-0.85. Cronbach alpha reliability coefficient of Medical Faculty Hidden Curriculum Scale consisted of 25 items was 0.8945. Scale was having construct and content validity.

Conclusion: Medical Faculty Hidden Curriculum Scale was developed which have “scientific thinking, discussion and searching skill”,“utilization of stage”,“physician skills”,“instructor objectivity”,“being decisive, tenacious and sistematic” and “having not rote learning” subscales.
