93% of districts report substitute teacher shortages, forcing regular teachers to cover classes during their only planning period — the one hour they have to prepare lessons and grade work

In recent national surveys, 93% of school district leaders report some level of substitute teacher shortage, with 77% calling it 'considerable.' When a teacher is absent and no substitute is available, districts resort to a cascade of bad options: pulling other teachers from their planning periods to cover the class, splitting students among neighboring classrooms (increasing those class sizes by 5-8 students), or placing paraprofessionals or administrators in front of students they are not trained to teach. The substitute pay rate — a median of $17.97/hour with no benefits, no guaranteed hours, and no pay during breaks — explains why the applicant pool has collapsed. The planning period is not a break. It is the only time during a 7-hour instructional day when a teacher can grade assignments, respond to parent emails, prepare materials for the next lesson, collaborate with colleagues, and complete mandatory documentation. When that period is taken for coverage, all of that work shifts to before school, after school, or home — unpaid hours that push the effective hourly wage even lower. Teachers report that losing planning periods 2-3 times per week is a primary driver of burnout, because it creates a choice between doing their job poorly (not grading, not planning) or doing it on their own time (not sleeping, not seeing family). The root cause is economic: substitute teaching pays poverty wages for irregular, unpredictable work with no benefits. A person willing to work in a school for $17.97/hour can earn more at Target ($15-24/hour with benefits and consistent scheduling) or driving for DoorDash. Districts cannot raise substitute pay without board approval and budget reallocation, and most district budgets are 80-85% personnel costs with little flexibility. The result is that the substitute pool has dried up, and the cost is silently transferred to regular teachers in the form of lost planning time — an invisible subsidy that does not appear in any budget line item.
