Why districts partner with HelloSubs

Built to work with your district — not replace it.

Whether you need a few extra subs on your hardest days or a pool rebuilt from the ground up, HelloSubs fits around the systems and people you already have.

Keep the systems you already use

No rip-and-replace. HelloSubs integrates with — or works right alongside — your current absence management and HR systems, so your team keeps the workflow it already knows.

Supplement your sub pool

Backfill the gaps your internal pool can’t cover — the Mondays, the Fridays, the flu weeks. No upfront fees, no minimums, no long-term contract.

Live human support

We work as an extension of your HR team, with live phone & email support Sunday through Friday. When something comes up at 6 AM, you reach a person — not a ticket queue.

We can build your pool

Fill rates already strong? Keep doing what works. If they’re slipping — or your teachers hesitate to use the subs you have — we build the pool for you. We generate thousands of applications every week and hire only the best.

Training built for your district

Customized training and orientation guides for your district — not an hour of someone talking. AI-enabled, scenario-based practice that actually improves how subs perform in your classrooms.

Educators who want to be there

Stop relying on your students’ parents to cover classrooms. HelloSubs brings you teachers who chose this work — and want to be in front of your students.

Simple, transparent pricing

No upfront or monthly fees. Only pay for days worked.

Unlike traditional staffing agencies that charge a percentage of wages, our fee is a flat daily rate — so more money goes to the teacher and more savings stay in your budget. Districts get volume pricing built around their campus count — we’ll walk you through it on the call.

Frequently asked questions

Substitute staffing for K-12 districts.

Do we have to replace our absence management system?+
No. HelloSubs integrates with — or works right alongside — the absence management and HR systems you already use. Your team keeps its workflow; we fill the openings your pool can’t. If you don’t have a system you love, ours is included free.
Our fill rates are already good. Is HelloSubs still useful?+
Possibly — as a backstop. Many districts keep their own pool as the first call and use HelloSubs for the gaps: high-absence days, hard-to-staff campuses, and long-term leaves. If you’re already well covered, we’ll tell you that on the call.
Can you build us a substitute pool from scratch?+
Yes. We generate thousands of applications every week, and every sub completes background checks, credential verification, reference checks, and an interview before their first assignment — then district-specific training before they reach your classrooms.
What does the training look like?+
Instead of an hour-long orientation lecture, subs work through AI-enabled, scenario-based training and orientation guides customized to your district — your procedures, your expectations, the situations they’ll actually face.
Can we request the same substitutes again?+
Yes — and most schools do. When a sub works well in your building, you can ask for them by name on future openings. Familiar subs need less orientation and keep classrooms running the way your teachers set them up.
How does pricing work for districts?+
A flat fee per substitute, per day — never a percentage of wages — with volume pricing for districts. No upfront cost, no monthly minimum, and you only pay for days worked. We’ll build your quote on the call.
Can you cover long-term absences and leaves?+
Yes. Alongside day-to-day coverage we place substitutes on long-term assignments — parental and medical leave, sabbaticals, and vacancies you’re still recruiting for.

Keep what works. We’ll fill the rest.

Supplement your pool, rebuild it, or back it up on your hardest days — and protect instructional time with substitutes your teachers will want back.
