Certified Substitute Application Procedure


    Thank you for your interest in the Deer Valley Unified School District! Providing quality Guest

    Teachers and Substitute Staff for our students is among our top priorities.


    Deer Valley Unified developed a community partnership with Educational Services, Inc. (ESI) to

    provide support and resources for guest teachers who play a vital role in delivering a quality

    education and ensuring student success.


    Founded by three educators in 1999, ESI is the founder and leader of the return-to-work/phased

    retirement program in Arizona, and the largest provider of substitute teacher services in the state.


    ESI’s SubSource program offers many benefits for school districts and employees who serve as

    substitutes in ESI client districts. This partnership also provides districts with an efficient tool to

    assist during legislative mandates and tight budget constraints.


    ESI’s solutions help districts save time and minimize HR costs while providing substitute teaching

    professionals with employee benefits and resources.



    Come join our partnership and make a difference in the lives of
    Deer Valley’s students and community!
