A Proactive Approach to Substitute Staffing

Written by STS Staff | September 15, 2026

Across the country, schools are faced with teachers retiring early, a spike in teacher burnout, and a dwindling pool of substitute teachers. At the same time, schools are competing to attract new families and maintain current enrollment. Families are seeking a school environment that is personable, consistent, and productive, despite the school’s staffing realities.  
  

Chain Reaction 

When a teacher is absent, it has a chain reaction to the school. That effect is magnified when administrators cannot procure substitute teachers. In those instances, fellow teachers and administrators must fill the vacancy. The costs of colleagues covering one another are numerous: they have less time to plan, grade, meet with parents, and recharge.  

According to the nonprofit public policy organization Brookings: 

"Chronically absent teachers can cause their classes to stagnate and potentially compel colleagues to work harder to pick up the slack."  

Covering for colleagues when substitutes cannot be found adds to the responsibilities that lead to teacher burnout. In the United States, K-12 workers have the highest burnout level of all industries nationally, and the burnout gap between K-12 workers and all other workers has increased. Preventing this growing burnout is a formidable task for school leadership. Having a sufficient supply of quality substitute teachers is one remedy.  

Of course, principals and assistant principals can also cover classes, but at what cost? When administrators must cover a class (or several), they are not performing their intended responsibilities. If there is a discipline issue in the school and the school leaders cannot address it promptly, it can disrupt multiple classes and affect other teachers and students. Office staff also feel the impact when administrators are unavailable, as they may have to handle parent, teacher, and student concerns. When administrators return from covering classes, they are often bombarded with multiple urgent items, which can be chaotic.  
 
 

Have a Plan in Place 

School leaders are keenly aware of the impact competent substitute teachers have on schools. When (not if), academic achievement suffers due to an inadequate supply of substitutes or merely mediocre substitute teachers; it’s the students who pay the price.  

Without a plan in place which provides consistency and quality, parents may decide to pull their students (and their tuition) from the school. For these reasons and more, school leaders must be proactive rather than reactive in the quest for quality substitute teachers.  

Deciding to work with a substitute teacher staffing agency–an agency specifically designed for the educational sector and dedicated to pairing competent, reliable, well-trained substitute teachers–increases the likelihood of a successful match that can be a foundation for future success. The cost-both financial and academic is well worth the investment.  
 
 

Selecting A Substitute Teacher Staffing Agency 

If you've never worked with an education-specific agency, here are some key items to seek out: 

Research their experience, reputation, and quality of subs. 

Find out their fill rate—this speaks to how proactive they are in connecting schools and subs.  

Determine if they are a good cultural fit for your school. 

Establish their support availability—Can they efficiently troubleshoot when something goes wrong? 

Do they provide support and mentorship to their subs? 

Is their service flexible and customizable? 

Do they have a streamlined system that enables hassle-free staffing (i.e., a user-friendly online platform)? 

Schools should look to avoid a staffing agency that places their people in a school and leaves them to fend for themselves. A first-rate agency will offer ongoing education and support to the substitutes they place, continually check in with school leaders to ensure placements are going smoothly, and provide access to an efficient customer experience team. Working with a staffing agency should not feel like a risk to a school and its students but rather an investment in the school's future.
