If adoption is the starting point, implementation is the journey, and it is longer and more complex than many systems anticipate. It is easy to assume that meaningful shifts will happen in math classrooms as soon as new materials are selected. However, districts that see lasting results understand that implementation takes time.
For district and building leaders, setting this expectation early matters. Stakeholders need to understand that an investment in a new mathematics curriculum is not an immediate solution. It is a long-term commitment to building stronger instruction over time.
A strong implementation journey typically unfolds across phases:
Year 1: Develop Goals, Foster Consistency, and Build Strong Instructional Habits
Educators and leaders build understanding, establish routines, and begin navigating early challenges. Inconsistency is expected as teams work to align around shared goals and practices.
Year 2: Deepen Instruction and Scale Success
Instruction becomes more consistent. Teachers refine their practice and strengthen their use of the curriculum, and leaders reinforce clear expectations across classrooms and schools.
Year 3 and Beyond: Refine Conditions to Sustain Implementation Success
The work becomes embedded. Systems and structures are refined to support long-term success, internal capacity grows, and districts can sustain and adapt their implementation over time.
This progression reflects the reality that meaningful instructional change develops over time. It comes as a result of sustained focus, adjustment, and continuous improvement.
We saw this firsthand in our work at San Tan Heights K–8 in Arizona. In year one, we jumped into implementing high-quality instructional materials in math. It was a hard start. We quickly realized that while the materials were strong, we hadn’t yet built the shared vision and classroom conditions needed to support them.
We decided to pause and refocus. We invested in building a clear vision for instruction, strengthening classroom culture, and aligning expectations across the building. Teachers welcomed the shift because it brought clarity and made the work feel doable. From there, we were able to get classrooms back on track and move forward with more consistency and purpose.
That experience shaped how we approach implementation today. Before diving into a new curriculum, we work with schools to make sure the right conditions are in place before implementation of a new curriculum. When foundations are strong, the work is not only more effective but also much more sustainable.
One of the most common implementation missteps is treating professional learning as something designed only for classroom teachers. Successful implementation requires a systemwide approach, and professional learning should be designed with all stakeholders in mind. This ensures that each group has the knowledge and support needed to lead and sustain a curriculum adoption.
Great Minds believes that curriculum implementation is a shared responsibility and that lasting instructional improvement requires coherence across all levels of the organization.
Professional learning must include:
School and district leaders
Instructional coaches
Classroom teachers
Interventionists and specialists
Special education teachers and paraprofessionals
When key groups are excluded, misalignment grows and consistency suffers. If the goal is a coherent instructional system, everyone responsible for supporting students must be part of the learning.
One of the most overlooked factors in successful implementation is principal capacity. Principals serve as the link between district vision and classroom practice. They set priorities, shape culture, and reinforce expectations. When principals lack clarity, time, or support, implementation efforts lose momentum.
Research on principals navigating significant challenges highlights this reality. Leaders are often expected to implement major initiatives while managing competing demands. Successful leaders consistently identify coaching, peer networks, district support, and professional learning as essential resources (Durham, 2025).
These findings align with broader research on educational change. School and district leaders play the central role of leadership in sustaining improvement (Fullan 2016). The work of a school and district leader is complex—implementation success depends on the systems supporting the entire classroom, not just the program itself (Fixsen 2005). Implementation within and across buildings in a system succeeds when new demands are matched with adequate resources (Demerouti et al., 2001; Bakker & Demerouti, 2007).
Even strong professional learning will not stick if systems are not aligned. Teachers often engage with multiple professional learning providers over the course of implementation, each focused on different initiatives. I recently visited a school where a teacher shared concerns about the lack of coherence across these experiences. Over the course of the year, the teacher interacted with four to five professional learning providers, each advancing a different priority. The result was fragmented support, with competing messages pulling teachers in different directions rather than building toward a common vision.
Implementation must be embedded into the structures educators rely on every day. Research on school leadership and improvement (Grissom et al., 2021; Leithwood et al., 2020) highlights the importance of aligning these organizational conditions:
Professional learning communities
Coaching cycles
Instructional walkthroughs
Data conversations
When these structures reinforce shared expectations, they accelerate progress. When they are misaligned, they create confusion and fragmentation.
Implementation is a human endeavor before it is a technical one.
Many districts approach implementation in reverse, adopting a curriculum and then trying to build support around it. But the districts that see real traction start in a different place. Before a single lesson is taught, they spend time building a shared vision for instruction and getting clear on what they want teaching and learning to look like.
A stronger approach begins with the conditions for success:
A shared vision for instruction
Clear expectations for teaching and learning
An understanding of current strengths
Support for building classroom culture
Districts that achieve lasting results plan for the long haul.
They understand that change increases demand on educators, that meaningful shifts in practice require time to develop, and that systems must evolve alongside instruction to ensure those changes take hold.
Most importantly, they invest in sustained support over time. Meaningful implementation does not happen all at once; it develops, deepens, and strengthens year by year.
