Remembering Siegfried “Zig” Engelmann

Remembering Siegfried "Zig" Engelmann

November 26, 2025, would have marked Siegfried “Zig” Engelmann’s 94th birthday. He passed in 2019 after an amazingly productive and full life. Zig was the creator of Direct Instruction (DI), beginning with his work in education in 1965. Zig devoted most of his life to bettering the lives of children by applying his theory of instruction to a set of instructional programs that are unparalleled in their efficacy with all learners, particularly learners at risk for failure. Prior to his passing, he had written over 100 instructional programs, 30 books, and hundreds of articles and papers.

NIFDI was founded by Zig to work with schools worldwide to implement Direct Instruction with a high level of fidelity. We are proud to continue his legacy of helping all students realize their highest potential with DI.

What is a Peer Coach?

Peer coaches play a critical role in sustaining strong implementation of Direct Instruction (DI) at the school level. Selected during the first year of implementation, peer coaches are classroom teachers who demonstrate strong instructional practice, effective communication with colleagues, and a willingness to support others. Because they teach the same programs as their peers, they bring practical expertise and shared experience that help build trust and collaboration across the school.

As implementation progresses, peer coaches extend the impact of NIFDI consultants by providing ongoing, school-based support when consultants are not on-site. Their coaching is non-evaluative and focused on improving student outcomes. Peer coaches reinforce effective teaching practices and guide colleagues to make targeted adjustments that directly impact student performance and behavior.

Peer coaches participate in a structured, multi-year training sequence through NIFDI. Over the course of two to three years, they are trained to analyze student performance data, conduct both brief and extended classroom observations, and support data-driven problem solving. Advanced training prepares them to lead grade-level meetings and contribute to broader instructional planning with school leadership.

By developing peer coaches, schools build internal capacity to maintain and strengthen DI implementation over time—ensuring continuity, supporting new staff, and driving sustained student achievement.
