How a K–8 School Expanded Reading Intervention Access by 39% and Strengthened Literacy Outcomes
The Challenge
When school leaders reviewed their literacy data, they identified a concerning trend: reading performance was declining, and an increasing number of students required additional support to meet grade-level expectations.
The school had a dedicated team of educators and interventionists committed to helping students succeed. However, leaders recognized that more students needed intervention services than the current system could effectively support. They also wanted to ensure that students were receiving the right intervention—matched to their identified needs.
Like many schools, intervention schedules, group structures, and service delivery models had evolved over time. The challenge wasn't a lack of resources or commitment. The challenge was ensuring that existing resources were being used strategically and that interventions were aligned to students' specific literacy needs.
School leaders partnered with New School Consulting to answer a critical question:
How can we provide targeted interventions to more students?
Conducting the Reading Intervention Audit
To address these challenges, New School Consulting conducted a comprehensive reading intervention audit focused on:
Student literacy data
Intervention schedules
Staffing allocations
Student intervention groups
Intervention intensity and frequency
Alignment between intervention programs and skill deficits
Data-based decision-making processes
Intervention capacity and resource utilization
Research consistently demonstrates that students make the greatest gains when interventions are matched to their specific skill deficits rather than solely to an overall performance level. Effective intervention requires schools to identify not only which students need support, but also what skills those students need to develop.
As part of the audit, we examined whether intervention services were aligned to students' actual literacy needs and whether intervention groups were structured to allow educators to provide targeted instruction.
The goal was not simply to identify areas for improvement. The goal was to create a strategic plan that would expand intervention access, strengthen instructional alignment, and maximize the impact of existing resources.
From Data to Action
The audit revealed several opportunities to improve efficiency while increasing access to support.
One of the most significant findings was the need to better align interventions to student skill gaps. While overall risk levels remain important, students often require support in different areas of reading development. Two students identified as needing intervention may have very different instructional needs.
Using student performance data, intervention groups were reorganized to better align instruction with identified literacy skill deficits. This approach aligns with recommendations from the Institute of Education Sciences (IES), which emphasize the importance of using student assessment data to identify specific literacy needs and provide targeted intervention. Rather than grouping students solely by overall performance level, the school reorganized intervention groups to better match instruction to the underlying skills students needed to develop.
The school also refined scheduling practices and intervention structures to ensure intervention resources could reach more students while maintaining quality instruction.
Rather than investing in additional personnel or implementing new programs, the focus was on strengthening the systems already in place.
Expanding Access to Reading Intervention
The results were significant.
Following implementation of the audit recommendations, the school increased its intervention capacity from 187 students to 260 students.
That represents 73 additional students receiving targeted literacy support— a 39% increase in intervention access without adding intervention staff.
The revised intervention model also increased available intervention time from 1,445 minutes per day to 1,555 minutes per day, creating an additional 110 minutes of intervention support each day.
At the same time, the school streamlined intervention delivery by reducing the number of intervention groups from 56 to 53, creating a more efficient and sustainable service model while serving significantly more students.
Early Evidence of Impact
While many factors contribute to student achievement, the school observed encouraging literacy outcomes following implementation.
Using DIBELS Composite Score data, the percentage of students identified in the Intensive risk category decreased from 66% at midyear to 54% by the end of the school year.
At the same time:
Students meeting benchmark or above benchmark increased from 21% to 28%
Students performing above benchmark increased from 7% to 11%
More students moved out of the highest-risk category and into less intensive levels of support
Although student growth is influenced by many factors, these results suggest that increasing access to intervention and improving alignment between student needs and instructional support helped position more students for reading success.
Why This Matters
One of the biggest misconceptions in education is that improving outcomes always requires more staff, more funding, or a new program.
The National Center on Intensive Intervention (NCII) tells us that intervention effectiveness depends not only on the intervention itself, but also on how well it is implemented. Schools achieve stronger outcomes when they use data to identify student needs, match interventions to those needs, and create systems that ensure resources are being used effectively.
In many schools, intervention challenges are not caused by a lack of programs. They are caused by systems that make it difficult to ensure students receive the right intervention at the right time.
This project demonstrates the power of combining data analysis, MTSS best practices, strategic planning, and implementation support to improve student outcomes.
By strengthening systems rather than simply adding programs, the school was able to:
Increase intervention access
Improve service delivery efficiency
Better align interventions to student skill deficits
Strengthen MTSS implementation
Create more opportunities for students to receive targeted literacy support
Improve reading outcomes for students across the school
Looking Ahead
The educators at this school were already deeply committed to helping students become successful readers.
By taking a closer look at how intervention services were organized, delivered, and aligned to student needs, they were able to significantly expand access to support and create a stronger foundation for literacy growth.
School improvement doesn't always begin with additional resources.
Sometimes it begins with asking better questions, using data strategically, and ensuring every student receives the support they need to succeed.
