NIFDI services are interlocking components.  Every component addresses a specific aspect of the implementation and without any one component, the overall effect on students' learning suffers. NIFDI's primary interest is working with schools to develop fully realized Direct Instruction schools where all children succeed.  For this reason, NIFDI does not generally provide the components separately.  An exception is made for pilot programs that could build toward comprehensive implementations of DI.

IMPORTANT:  The description of each of these services is accompanied by a box like this one that describes the consequences of for going or not implementing any of the services fully.  Forgoing any one service can have a negative effect on student performance.
