In a study by Century and Levy (2002), sustainability is defined as “the ability of a program to maintain its core beliefs and values and use them to guide program adaptations to changes and pressures over time” (p. 3). You and your team will want to consider how you can sustain and increase practices that are aligned to your literacy goals and the guidelines laid out in the TSLP.
Sustainability of practices is particularly a concern when temporary funding is used to support improved practices. Ideally, conversations about sustainability take place as use of temporary funds is planned, and they continue throughout a grant or temporary funding period, not just as the end of the funding is approaching. You can see examples of ways to build sustainability in Level D of each Action Step except those in the Sustainability module, which has only Levels A through C.
There are common threads throughout Level D in the Leadership, Assessment, Standards-Based Instruction, Effective Instructional Framework, and Reporting and Accountability components. You will notice that some Indicators in Level D focus on establishing systems for monitoring progress toward literacy goals and evaluating the effectiveness of literacy initiatives. Others focus on establishing written policies and procedures to share when there are personnel changes. Professional development is a strong thread throughout the TSLP, and in Level D, you are reminded to provide professional development to new staff to ensure that all staff members have the capacity to implement the practices and skills targeted in your literacy improvement efforts.
As this process progresses, the culture of the organization can be transformed. “The new way” becomes “the accepted way” and eventually becomes “the way we do education here in our school, district, or state” (Fixsen & Paine, 2009, p.14).

NEXT STEPS: Depending on your progress in implementing the TSLP, you may want to consider the following next steps:
- Use the six-step “TSLP Implementation Process: Working on an Action Step” and, as a team, create or update a TSLP implementation plan for your school.
- Communicate your plan with all stakeholders and involve staff in executing your plan.
- Maintain a regular meeting schedule for your campus-based leadership team to evaluate progress toward goals and plan for next steps.
- Review Level D in each Action Step and determine what systems need to be established or reviewed and what policies and procedures need further development.
