Introduction: There is a dearth of standardized instrument to ass the lifelong leaning capabilities of nurses. This study aimed at evaluating some of the psychometric properties of the Clinical Learning Organisational Culture Survey (CLOCS) in Iranian context.

Methods: The sample study comprised of 327 nursing staff affiliated to government educational hospitals in Rasht- I. R Iran during 2013. The participants voluntarily completed the COLS, comprised of 28 items with five sub scales. Data were computer analyzed, using LISREL 8. 75, person correlation and confirmatory factor analysis.

Results: Confirmatory factor analysis yielded promising results by segregating the previous five factors, namely, dissatisfaction, applicability, dependency, and influence. (GFI=. 89 CFI=. 90 RMSEA=. 08). They turned to show highly reliable internal consistency and factor structure. Respectively (0/71), (0/52), (0/74), (0/64), (0/53).

Conclusion: Henderson’s COLS is a highly reliable and valid scale which can have strong holding in evaluating educational system in Iranian context.
