What is SubSource?

SubSource is ESI’s program to staff substitutes for 60+ school districts all across Arizona

Who are substitutes?

They are people just like you! ESI’s substitutes come from a wide-range of backgrounds, ages, cultures and experiences. Some are former teachers, many aren’t. The one thing they all have in common is a desire to help students.

Freedom & Purpose

Enjoy a flexible job, where you choose which age students to work with, which subjects to teach, which schools to serve and even which days you want to work. School districts need substitutes, so there are always plenty of positions to choose from.

Plus, you can feel good about the work you do each day. Improving students' lives through education improves your community. There's no other job out there which has so much freedom and real purpose.

Why Join ESI?

We work with more districts throughout Arizona than anyone else.
As a result our substitutes get more opportunities for work.

ESI and district support

Substituting with ESI: Two Teams, One Goal.

ESI is hired to provide substitutes for school districts. You will be a W-2 employee of ESI, though you will work each day at your chosen school district.

One thing we hear often from our substitutes is how they appreciate having the support of two teams. You see, as an ESI substitute, you get the support of the school district and ESI. You'll feel like you are a valuable part of both teams.

For instance, you can call our Employee Services team and a someone will be there for you. You will also work closely with your school district's substitute coordinator. They are remarkable people. Learn about Chris or Angie who are incredible substitute coordinators for their school districts.

ESI is not just a "staffing company". We are really an "educator company". Education is our specialty and our mission is to make sure no school position goes unfilled. You are not a contractor; you are a member of the ESI family. Together, we will elevate our Arizona community.

5,000+ substitutes?! That's a big teacher's lounge.

Our large team benefits you. Because ESI serves over 60 school districts all over Arizona, you have more options and opportunities for work. Chances are, there's a school district near you who uses ESI.

Experienced and Personal

Founded in 1999 by three educators here in Arizona, we have grown to become the leading provider of staffing services in education. One thing that has stayed the same in 20+ years is our commitment to people. We are still a family business and if you call or email us, you'll immediately appreciate our responsive, personal service.

Humans First

ESI's onboarding and employee service portal are designed with you in mind. Constantly improving, it gives you complete access to your pay stubs, leave information and benefits. You can call, email or text. Our team will be there for you.

Flexible Work, Dependable Pay

Because of our experience and our size, you are cared for by professionals. Even though you work whenever you want, your paychecks will be accurate, and they will be on-time. You will feel connected with regular email communication, social media updates and a dynamic website.

Access to Benefits

Additionally, we believe access to benefits are important for all employees. We lowered the minimum hours required to only 900 hours so you can qualify to buy our affordable, quality insurance. You will also accrue 1 hour of Paid Sick Time for every 30 hours worked, up to 40 hours per year.

Putting the "Professional" in PD

Finally, whether you are a seasoned educator or new to this profession, you will quickly appreciate our Professional Development resources. Even if you are little worried about that first day as a substitute, there's plenty of support to get you ready.

With help from Arizona State University, ESI is pleased to offer the Sanford Inspire online training program to all of our employees. It's the best-of the best in educator skills development with over 30 modules. You'll also have access to our SafeSchools virtual training program. Our substitutes have taken 1,000s of SafeSchools and Sanford Inspire courses, improving their valuable job skills at absolutely no cost.
