I know that curricular is an adjective and curriculum a noun, but are they both used in exactly the same meaning? Or are there some differences concerning what they imply or apply to? Being a non-native English speaker I would say that they are the same or at least are used as synonyms. I would prefer to use "curriculum framework" but quite often the translation e.g. from German 'Rahmencurriculum' is made with "curricular framework".
It is clearly not curricular framework in OP's case.
A framework curriculum is a sample/ model built on the basis of guidelines (the 'framework'). Individual institutions can design their curricula on this model, or probably adopt it as such.
A curricular framework (loosely, curriculum framework) is a set of guidelines defining and explaining what a curriculum is required to be like or contain.
