For more information about systems thinking and how it can be used by state education agencies (SEAs) to support district-wide improvement, see the Moving Your Numbers publication, The Critical Role of SEAs in Facilitating School District Capacity to Improve Learning and Achievement for Students with Disabilities (NCEO, 2012). For more information about improvement models, such as Improvement Science and the Collective Impact Framework, go to the Improvement Frameworks section of the Tools & Resources tab.

The delivery of services by SSTs is guided by the following non-negotiables undergirding Ohio’s statewide system of support:
- Improvement is everyone’s responsibility.
- Improvement requires all components of the system (state, regional, district, school, classroom, community) to work together.
- Districts play a key role in improving outcomes for all students across the system.
- Fidelity of implementation of the right strategies to meet district needs is necessary and sufficient to achieve sustainable improvement on behalf of all students.
- All SST functions (e.g., services related to special education, early learning, literacy, etc.) should be delivered in a coherent fashion using the OIP improvement framework.
- A unified statewide system of support requires the intentional use of a consistent set of tools and protocols (e.g., support documents) by all state-supported regional providers (rather than allowing for multiple approaches across the state, based on preference).
