Continuous Improvement

Continuous Improvement is a set of principles and practices to help educators “get better at getting better.” Marshall’s Continuous Improvement team uses these tools to tackle intricate, systems-level problems in K-12 education. Currently, we support a multi-year Networked Improvement Community (NIC) to make dramatic gains for Black and Latinx students with disabilities experiencing poverty.

Networked Improvement Community for Students with Disabilities

Marshall is a part of the Networked Improvement Community for Students with Disabilities (NIC). Made possible by the Bill & Melinda Gates Foundation and alongside technical assistance providers SWIFT Education Center, NIRN, RTI International, and SRI International, the NIC’s goal is to systematically improve the way our education system serves Black and Latinx students with disabilities experiencing poverty and bring these solutions back to school systems everywhere. The pilot community is made up of 10 charter management organizations that collectively serve more than 75,000 students around the country.

Public schools across America struggle to meet the diverse needs of students, particularly those farthest from opportunity. When marginalization intersects with disability, students often face low expectations, are systematically segregated, denied access to college and career curriculum, and do not receive sufficient support to obtain a high school diploma and pursue their dreams. Nationwide, students with disabilities represent 13.7% of all enrolled students — totaling almost 7 million students in the 2017-18 school year.

As a network, we have the opportunity to change that story for these students by applying the science of improvement to identify positive deviants, share best practices, and scale solutions across the system.

Marshall's Approach

    Continuous Improvement and Targeted Universalism

    We use the tools of continuous improvement to identify students who are positioned furthest from opportunity within a system and partner with young people and community members to improve the system. This approach marries the technical and adaptive expertise of improvement science with the philosophy of targeted universalism to drive system improvements that produce more equitable learning environments and outcomes.

    Tailored for Each Community

    Because all communities are different, we must be adaptive to a range of needs. The specific roles and responsibilities, systems and structures, and processes and protocols must be tailored to the people they serve. Each community also has its own working norms, knowledge and expertise, relationships, and localized best practices that must be built into the Continuous Improvement process.

    From Problem Statement to Change Packages

    Improvement efforts start with a Problem Statement that defines a systemic problem experienced by students. We create a specific and measurable goal, or Aim, to guide our collective effort in solving the problem. Commonly understood and constantly revised Theories of Action guide where and how teams can introduce changes to reach their Aim. Through rigorous testing and measurement, we codify those learnings into Change Packages so that others can enact the changes as they spread and scale.

Our History of Improvement

Marshall Street launched the Continuous Improvement initiative in 2019, using the learnings from Summit Public Schools. Since 2013, Summit has used the tools of continuous improvement to make sizable gains in student outcomes. Our work in reducing inequity in academic outcomes for our English Learners was recognized with the Carnegie Spotlight on Quality in Continuous Improvement.

As Marshall, we continue to grow our expertise in systems and structures for improvement, data collection and analysis, and synthesizing and disseminating actionable knowledge. Today, we are part of a nationwide networked improvement community for students with disabilities.
