This paper presents a picture of the feasible implementation of the newly proposed National Curriculum in Iran, and attempts to show that how much “the implementing considerations of this curriculum” fits with the “global and national experiences” of curriculum implementations. For this purpose, the author analyzed the relative documents and observations. The study showed that the implementation of large scales curriculum requires four levels of decision makings including; definition of views, indication of approaches, selection of methods and establishment of an implementation style. Although there is a compilation of positive experiences in the past regarding curriculum implementations, it seems that writers of the proposed National Curriculum have not taken them into consideration. On the contrary, it looks like that the writers prefer to use a differenciative view, engineering approach and incremental method for the implementation of the proposed National Curriculum in which, some parts of the present curriculum is accepted as suitable along with the implementation of the proposed curriculum. As well, the implementation of a program necessitates the agreement of stakeholders, human resources, facilities, and monitoring. But, in describing the implementation of the proposed document, there is little or no attention pays to these four categories. However, for the evaluation of the necessary requirements for implementation of the National Curriculum of the I.R. of Iran, the valuable experiences of the evaluation of two educational systems in Iran and the international experiences have been available and yet, it seems that this document has been prepared independent of these experiences.
