It is 6:15 a.m., your phone alerts you to an available classroom assignment, and you have only a short time to decide whether to accept it. For teachers on call, that kind of morning can be normal. The work offers flexibility and valuable classroom experience, but assignments, income, and expectations may change from day to day.
The phrase teachers on call generally refers to substitute educators who temporarily replace absent classroom teachers. Some work directly for a school district, while others receive assignments through staffing agencies or digital scheduling systems. Understanding the qualifications, pay structure, and career possibilities can help you decide whether this flexible education role fits your goals.
What Do Teachers on Call Actually Do?
A short-term substitute usually follows lesson plans left by the regular teacher. However, the job involves much more than handing out worksheets. Teachers on call are responsible for maintaining a safe, productive classroom and helping students continue learning with as little disruption as possible.
Typical responsibilities include:
- Taking attendance and following the school’s daily schedule
- Explaining assignments and answering student questions
- Managing classroom behavior fairly and consistently
- Supervising hallways, lunch periods, recess, or dismissal
- Following emergency, health, and student-safety procedures
- Leaving notes for the regular teacher about completed work and classroom events
Assignments may last one day, several days, or longer. Short-term substitutes typically rely on the classroom teacher’s plans, while long-term substitutes may prepare lessons, grade work, communicate with families, and perform many of the duties of a permanent teacher.
What Education and Credentials Are Required?
There is no single nationwide qualification that applies to every substitute position. Requirements depend on the state, school district, grade level, assignment length, and type of school. A district may accept applicants with a high school diploma or a certain number of college credits, while another may require a bachelor’s degree, teaching license, or substitute permit.
Common hiring requirements include:
- A high school diploma, college credits, or a bachelor’s degree
- A criminal background check and fingerprinting
- Proof of identity and authorization to work
- Official college transcripts when higher education is required
- A state or local substitute teaching permit, where applicable
- Orientation or training in classroom management and school procedures
Public schools generally follow state and district rules, whereas private and charter schools may use different standards. Requirements can also be stricter for long-term placements, special education classrooms, or assignments in which the substitute becomes responsible for planning and assessment.
Is a Teaching License Necessary?
Not always. Some districts hire on-call teachers without full teacher certification, particularly for short assignments. Others require a temporary substitute credential or an active teaching license. Licensed educators may qualify for higher daily rates, specialized assignments, or long-term positions.
Before applying, check the district’s current job posting rather than assuming that requirements are the same throughout your state. Ask whether permits must be obtained before hiring, how long approval takes, and whether the district reimburses fingerprinting or application costs.
How the Hiring Process Usually Works
Candidates commonly complete an online application, provide transcripts or references, undergo a background check, and attend orientation. Once approved, they receive access to available assignments by phone, email, website, or mobile app.
You may be able to choose preferred schools, grade levels, subjects, and workdays. Accepting a wider range of assignments can produce more consistent work, but it is reasonable to begin with classrooms where you feel confident. For example, someone with experience coaching teenagers may prefer middle or high school, while a former childcare worker may be more comfortable in elementary classrooms.
Successful substitutes often build relationships with office staff and permanent teachers. Arriving early, following lesson plans carefully, and leaving useful notes can lead to repeat requests and longer placements.
Salary and Pay Factors
Teachers on call may be paid by the day, half-day, or hour. Compensation varies widely, so a national figure should be treated as a reference point rather than a guaranteed salary. The U.S. Bureau of Labor Statistics reports a 2025 median annual wage of $41,670 for short-term substitute teachers in its federal occupational projections for short-term substitute teachers. Actual yearly earnings depend heavily on how many assignments a person accepts.
Major factors affecting pay include:
- Geographic location and local cost of living
- District budgets and collective bargaining policies
- Education level and teacher certification
- Short-term versus long-term assignment status
- Experience and specialized subject knowledge
- Demand for substitutes in a particular school system
- Direct district employment versus staffing-agency placement
Some districts increase the daily rate after a substitute works a set number of consecutive days in one classroom. Hard-to-fill roles, including special education, bilingual education, mathematics, and science assignments, may also offer higher compensation in certain areas.
When comparing opportunities, look beyond the advertised daily rate. Consider unpaid school breaks, transportation costs, assignment cancellations, minimum work requirements, and whether preparation or training time is paid.

Do On-Call Teachers Receive Benefits?
Benefits are not guaranteed. Many substitute teachers work part time or on an as-needed basis and do not receive health insurance, paid leave, or retirement contributions. A district may provide benefits only after an employee meets a minimum number of hours or accepts a long-term placement.
Ask employers about eligibility rules, pay frequency, cancellation policies, retirement deductions, and whether substitutes are treated as employees or placed through an outside organization. These details can significantly affect the real value of an offer.
Job Growth and Employment Stability
Federal projections indicate that employment of short-term substitute teachers is expected to grow 2 percent from 2025 to 2035, with about 65,000 openings projected each year on average. Many openings are expected to come from workers leaving the occupation rather than rapid expansion.
Local demand can be stronger than national growth suggests. Schools need qualified adults when permanent educators are ill, attending training, taking family leave, or filling vacancies. Demand may fluctuate during the year, with fewer assignments during holidays and summer breaks.
Because daily work is not always predictable, some substitutes register with multiple districts where permitted. Others combine substitute teaching with tutoring, coaching, freelance work, or seasonal employment.
Skills That Make the Work Easier
A substitute may enter an unfamiliar classroom with little advance notice, making adaptability essential. Strong candidates communicate clearly, remain calm under pressure, and apply school rules without escalating minor problems.
Helpful skills include classroom management, organization, cultural awareness, basic technology proficiency, and the ability to explain instructions in more than one way. Reliability is equally important. Schools remember substitutes who arrive on time, protect student privacy, ask appropriate questions, and respond professionally when plans change.
Can Substitute Teaching Lead to a Permanent Career?
Yes. On-call teaching can provide practical experience for future educators and help career changers decide whether they enjoy working in schools. It also allows candidates to meet administrators, learn district procedures, and observe different grade levels before pursuing certification.
Advancement may involve obtaining a teaching license, accepting long-term assignments, becoming a paraprofessional, or applying for a permanent classroom position. Some people, however, intentionally remain substitutes because they value schedule control and variety.
Is This Career a Good Fit?
Teachers on call can make an immediate difference by giving students continuity when their regular teacher is absent. The role may suit you if you enjoy working with young people, can manage uncertainty, and want flexibility more than a fixed weekly schedule.
Before accepting a position, confirm credential requirements, realistic assignment availability, expected duties, daily pay, and benefit eligibility. A clear understanding of those details will help you decide whether substitute teaching is a temporary income source, a pathway into education, or a flexible long-term career.
