In short: Teacher shortages create more than an empty classroom; they create a pressurized system where remaining staff absorb the gap until a replacement is found, if one is found at all. According to the Learning Policy Institute, 48 states and DC employed nearly 366,000 not-fully-certified teachers in the 2024-25 school year, and roughly 1 in 8 teaching positions nationally are either unfilled or staffed by someone not fully certified. Replacing a single teacher costs a district between $12,000 and $25,000. Integrating HR with finance, payroll, and scheduling through an ERP system helps districts get ahead of this cycle: supporting upskilling and retention, cutting the administrative cost of recruitment, and using real data to understand why teachers actually leave.

Teacher shortages create more than just an empty classroom. When an educator submits their resignation letter, they create a pressurized system. Staff members who stay have to fill the void until administrators find a replacement. But what happens when they can’t fill the position?

The scale of the shortage is significant and well documented. According to the Learning Policy Institute’s 2025 analysis, 48 states and the District of Columbia employed an estimated 365,967 teachers who were not fully certified for their teaching assignments in the 2024-25 school year, and states reporting vacancy data showed 45,582 unfilled teaching positions. Taken together, roughly 1 in 8 teaching positions nationally are either unfilled or filled by someone not fully certified, a gap that affects more than 6 million students. When districts can’t fill positions, it wreaks havoc on the remaining staff, perpetuating an endless cycle of teacher burnout, absenteeism, and turnover.

It’s obvious why burnout in education exists:

• Oversized classrooms
• Mental and emotional labor
• Mental health crisis
• Toxic work cultures

People continuously ask how they can support teachers, but it’s also important to consider how to support administrators as they navigate this landscape. As administrators take these challenges head-on, it’s important for them to stop operating in silos. If district leadership isn’t collaborating to address teacher shortages, how can they expect the rest of their schools to do the same?

Every time a teacher resigns, it costs a district between $12,000 and $25,000, depending on district size. The time and energy spent just finding a replacement makes filling teaching vacancies that much harder.

Separated systems hinder Human Resources from doing its job effectively, burying HR in unproductive manual tasks. When HR lacks the functionality to generate reports quickly, it loses the capacity to find qualified candidates before someone else does.

Teaching candidates are a rare commodity. To keep school districts staffed and prepared, it’s vital to have systems that work together.

Benefits of HR integration for K-12 school districts

School administrators keep their entire district and network of staff members operating at a high level. With the guidance of the superintendent, each administrator oversees their own area of specialty, whether it’s:

• Director of Curriculum
• Human Resources
• Business and Finance
• Technology

These roles and their systems all play a key part in a district’s operations, which is exactly why integrating each separate system enables optimal management and efficiency.

Enterprise Resource Planning (ERP) helps integrate finance, human resources, and payroll systems, among others. Here are some of the benefits to your school district.

Upskilling: turning existing staff into your next specialists

HR needs help getting to the root cause of staff shortages to keep teachers engaged. Research on why teachers actually leave the profession backs this up directly: across OECD countries, about half of fully qualified teachers who leave the profession resign rather than retire, which points to retention, not just recruitment, as the real lever districts need to pull. After the novelty of teaching wears off, what can educators do to craft a fulfilling career? HR has the ability to proactively address stagnancy with thoughtful upskilling. Using systems to track qualification and training, teachers can find new, exciting career pathing that supports retention and quells burnout.

Education often only offers upskilling for teachers if it involves costly outside schooling. But school administration has a large pool of highly talented individuals with special interests and strengths already on staff. In need of professional development for a high population of English language learners? Instead of hiring an outside trainer with no relationship to the district, HR can track which teachers already have ELL students in their classrooms. The Director of Curriculum can then pay them to work with the district’s ESL teacher or supervisor to craft compelling internal training. With intuitive tracking built into an integrated HR system, HR has the potential to help staff reignite their passions through career pathways that already exist inside the district.

Cost effectiveness in recruitment

HR can save real time, especially in teacher recruitment. A 2024-25 survey found that 74% of districts had trouble filling their open teaching positions, which means every open role is effectively competing against every other district trying to fill the same kind of gap. HR’s time is far better spent on that competition than on manually inputting data, extracting it, or connecting disparate systems by hand. With an ERP, a Director of HR can add, modify, and approve job requisitions to streamline the hiring process. This saves a district’s time and resources in finding, and more importantly placing, the right candidate, which saves money over the long term.

Improved tracking of internal talent

With high volumes of teaching vacancies across the country, an ERP system helps HR build a centralized database of candidate information, including current teachers’ resumes and qualifications. When it’s difficult to fill a vacancy externally, HR has the potential to draw on existing staff to alleviate the gap. This isn’t a long-term fix, but it gives HR a genuine sense of relief during periods of high turnover, since there’s a whole pool of current staff to turn to rather than starting an external search from zero.

Combat teacher shortages with data for short-term and long-term planning

A streamlined standard procedure enables a smooth exit every time a teacher resigns. While administrators want to fill vacancies quickly, they also need to understand why the employee left in the first place, or resignations have a real chance of repeating themselves for the same underlying reason.

With an ERP system, HR gains real power to improve teacher retention rates. Centralized data, combined with a structured exit interview, helps districts with forecasting and long-term planning. For example, an ERP can generate real-time data on teachers’ workloads, schedules, class sizes, and student performance. These metrics help HR, Directors of Curriculum, and superintendents make informed decisions about offering authentic support and professional development. Backing an exit interview’s qualitative data with tangible metrics also helps district leaders defend budgeting proposals during challenging economic times. This kind of data-informed planning is exactly what Sparkrock’s research into K-12 district priorities identifies as a growing gap: districts often lack the centralized tools to track well-being trends and intervene before burnout turns into another resignation.

How to secure and onboard new teacher hires with more efficiency

Every time a teacher resigns, it leaves a gap that the Director of Human Resources and HR specialists have to fill as quickly and compliantly as possible.

Before they can even post the vacancy, HR needs to know the district’s codes and policies and how they align with federal and state regulations. With an ERP, HR has the power to run reports and ensure compliance for every job posting, application, interview, and hire.

An ERP system also helps bridge communication from an IT perspective. HR can share critical personnel information with the Director of Technology to ensure a new hire has access to email, grading portals, and other online resources from day one.

With an ERP, Human Resources can automate contracts, benefits, and payroll. ERP software also helps integrate and streamline document management when districts bring on new employees, letting staff share and save important information and documents without the headaches that come with chasing down paperwork later. Creative staffing approaches, like job sharing, flex scheduling, and engaging retired educators as mentors, become far easier to manage and track once scheduling and HR data live in the same connected system.

District-level management systems create a trickle-down effect in schools. Disorganized, separated systems foster miscommunication, inefficiency, and low morale. When school administrators merge their systems into one source of truth, they’re better able to handle the challenges in education with data-driven insight, especially when it comes to curbing teacher turnover.

Frequently asked questions

How severe is the current teacher shortage? Very. According to the Learning Policy Institute, 48 states and DC employed nearly 366,000 teachers not fully certified for their assignments in the 2024-25 school year, and states reporting vacancy data showed over 45,000 unfilled positions. Together, roughly 1 in 8 teaching positions nationally are unfilled or staffed by someone not fully certified.

How much does it cost a district when a teacher resigns? Between $12,000 and $25,000 per departure, depending on district size, once recruitment, hiring, and onboarding costs are factored in. That cost compounds when a district faces high turnover across multiple positions in the same year.

How can HR technology help improve teacher retention? By giving HR the data to understand why teachers actually leave, not just how to replace them faster. Integrated systems can track workload, scheduling, and exit interview data together, which helps districts address the root causes of burnout and turnover rather than just refilling the same positions repeatedly.

What role does an ERP system play in teacher recruitment and onboarding? It lets HR create, modify, and approve job requisitions in one system, run compliance reports for every posting and hire, and share new-hire information with IT and other departments automatically, so a new teacher has access to email, grading portals, and other systems from their first day rather than waiting on manual setup across multiple disconnected tools.
