Structural Gaps Keep the Educator Pipeline Blocked — and What Innovative Programs Are Doing Differently

Building the Educator Pipeline — Article 3 of 4

For years, the conversation about teacher shortages has centered on the wrong question. States and districts have debated certification requirements, debated who should qualify, and debated how much flexibility is reasonable under pressure. What they have largely not debated is the design of the system itself — and that is where the real problem lives.

By the time a district is making emergency hiring decisions, the pipeline has already failed. The vacancy is not the problem; it is the symptom. The problem is that most systems were never designed to build a teacher workforce intentionally. They were designed to credential people who had already decided, on their own, to become teachers — and to process them efficiently once that decision was made. That is a fundamentally different thing.

And the numbers making the decision to become a teacher AND successfully navigating the process to become certified are woefully short for many systems.

Four structural gaps show up repeatedly in systems that are struggling, and they are worth naming directly.

Teaching as a single point of entry - not a progression.

Most preparation systems are built around a credential: something you earn before you can begin. But experience, as the Texas research made clear, is the more reliable predictor of effectiveness than the credential itself. When the system has no structure for building experience before full classroom responsibility, it not only produces teachers who are certified but underprepared — it also excludes a significant population of adults who are already doing meaningful educational work. Paraprofessionals who know the students, the culture, and the school. Tutors, instructional aides, and community educators who bring context that no university program can replicate. These individuals are not outside the pipeline. They are in it every day. What is missing is a structured pathway that recognizes where they are and moves them forward from there, leaving significant talent on the table.

Part of what makes that structure possible is expanding who builds it. Districts that have successfully created multiple entry points have done so by broadening their partnership base well beyond the traditional university relationship. Community colleges offer accessible, affordable on-ramps for candidates who cannot commit to a four-year program before they begin earning. Adult education programs reach working adults already in schools who need flexible, stackable credentials. Nonprofit organizations — particularly those with deep community roots — bring local trust and recruiting reach that institutions often lack. And for apprenticeship models specifically, State Education Agencies and the Department of Labor are critical partners: they bring the regulatory frameworks, registered apprenticeship infrastructure, and in many cases the grant funding that makes paid earn-while-you-learn pathways financially viable. Building a pipeline that works for a broader range of candidates requires a broader range of partners — and districts that wait for a single university partnership to solve their workforce problem are likely to keep waiting.

Required clinical practice or pipeline filter.

Teaching remains one of the only professions where the entry pathway requires years of full-time study and unpaid or underpaid clinical practice before a livable salary begins. For candidates who cannot afford to step away from paid employment — which describes a large proportion of the people most likely to reflect the communities where teachers are needed most — the traditional model is simply inaccessible. A system that requires candidates to absorb significant personal cost before they can contribute is not a pipeline. It is a filter.

Good teachers don’t always make good mentors.

Experience matters and pre-service/novice teachers working with an experienced mentor can support building a classroom-ready teacher. But the mentor gap is not simply about whether a mentor is assigned or what an amazing teacher they are — it is about having a passion for mentoring and the preparation they have for that role. In a traditional placement with college age candidates, a mentor teacher guides a student teacher or new hire based largely on their own experience and goodwill with university supervisors who can support and evaluate. With today’s programs, this can be an insufficient foundation for a diverse candidate pool and extended clinical models.

In a residency or apprenticeship, the mentor is working with a candidate over a full year or more, observing regularly, providing structured feedback, developing teaching and district competencies, and sharing instructional responsibility for a classroom. Those are distinct and demanding professional skills — and most systems provide little to no formal training. Note, this also follows for other preparation apprenticeships such as paras and building leaders.

Data collection and systems is not a data culture.

Most systems do have data. What they lack is organization, transparency, and a culture where data is used to drive action. The systems that exist were largely built to manage the hiring funnel: who applied, who was credentialed, who was placed. What they do not track is the talent already inside the system and how it is — or is not — moving forward.

A tracking system that follows high school student interest, pre-service candidates by program, vacancies, hiring, selection, and retention would give leaders transparency across departments and schools. It would help them understand where talent comes from, how it moves through the district, where it gets stuck, who stays, who leaves, and what conditions predict success or attrition. That shift moves the conversation from “how many openings do we have” to “what patterns are causing our openings and how are our investments building a stronger workforce.”

Over time, a system like this makes it possible to see, for example, whether para-to-teacher candidates stay longer than external hires, whether early-career turnover is concentrated in certain schools, or whether mentor assignment is associated with stronger retention. That is the difference between managing a crisis and building a system.

Innovative programs doing things differently.

What makes these four gaps significant is not that they are unknown. It is that most systems have not yet restructured around them. Some are beginning to, and the results are instructive.

Texas’s scaled investment in teacher residencies — over 85 programs, more than 2,000 paid residents between 2021 and 2024 — is the most visible example of a state attempting to close multiple gaps simultaneously. Residency programs require candidates to spend a full year embedded in a classroom alongside a mentor teacher before taking on full responsibility. They are paid. And they are structured explicitly around co-teaching and mentorship rather than isolated practice. Critically, the Texas initiative also required districts to adopt strategic staffing models — restructuring educator positions to fund residencies sustainably after grant funding ended, rather than treating the investment as a one-time program.

Beyond this, Ector County, Texas, implemented team-based staffing alongside teacher residencies, the district reduced vacancies by more than 90 percent — from over 350 substitute teachers filling classrooms in 2019 to just 29 in 2024–25. That is not a policy adjustment. It is a structural redesign — and it required addressing not just who was in the pipeline but how the school itself was organized to receive and develop them.

The Opportunity Culture model, now reaching more than 200,000 students nationally, offers a parallel example — organizing schools around teams of educators at different experience levels, with experienced teachers in formal Multi-Classroom Leader roles earning meaningfully higher compensation funded through budget reallocation rather than new spending. Residents on these teams receive salaries rather than working unpaid. The model addresses three of the four structural gaps at once: it creates a paid pathway, it embeds mentorship into the daily structure of the school, and it builds the training and role definition that makes mentoring a genuine professional responsibility rather than an informal courtesy.

In Delaware, stackable pathways are building momentum, where the progression is playing out one educator at a time — and where the cost of a broken system is visible in years, not statistics. Phadre West spent more than a decade as a special education paraprofessional in Capital School District. She knew the students, the schools, and the work. She had tried to pursue a teaching degree in 2009, but financial barriers and structural roadblocks stopped her. The pathway existed in theory, she enrolled. In practice, it was inaccessible.

Thirteen years later, with the support of program director Sherri Hollis, Phadre became one of the first participants in Delaware's new para apprenticeship pathway — working full time alongside a mentor teacher while completing her degree at Wilmington University. This year, she is a confident first-year teacher whose students are among the highest performers in the district. And she is already being considered as a future mentor in the program that made her path possible. Her story is not just inspiring. It is instructive. The system did not need to lower its standards to reach Phadre West. It needed to build a pathway that met her where she already was.

What these programs share is not a single approach. They share a design philosophy: that preparation happens over time, in real classrooms, alongside experienced and well-supported practitioners, with financial structures that make access possible and data systems that make progress visible. That is the unlock. Not a new policy. A different architecture.

The question is not whether this architecture works — the evidence suggests it does. The question is whether the field is willing to move from isolated pilots to the kind of coherent, connected infrastructure that makes it the norm rather than the exception. Looking to hear more?
