Why school leaders choose HelloSubs

The same trusted faces, back again.

Consistency is what separates a staffing partner from a staffing agency. Every sub is background-checked, credential-verified, reference-checked and interviewed before their first assignment — and when one works well in your building, you can request them again.

Vetted before day one

Background checks, credential verification, reference checks, and an interview — every sub, every time.

4.9★ average rating

Rated by the schools they work in, across thousands of placements.

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. Multi-campus groups pay less per day, and districts of six or more qualify for additional discounting.

Frequently asked questions

Substitute staffing for K-12 schools.

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, know your procedures, and keep classrooms running the way your teachers set them up.
How do you ensure substitute quality?+
Every substitute completes a thorough vetting process — background checks, credential verification, reference checks, and an interview — before their first assignment. Schools rate subs after each placement, and those ratings shape who we send you next.
Are your substitutes certified or licensed?+
Requirements vary by state and role, and we place to your state's rules. Where a substitute license or teaching certificate is required, our subs hold it — and we help candidates through the licensure process so your openings aren't limited by paperwork.
How does the volume pricing work?+
Our fee is a flat rate per substitute, per day — never a percentage of wages. One campus is $35/day. Two to five campuses are $33/day. Groups and districts running six or more campuses qualify for additional discounted pricing — tell us your campus count and we'll build a custom quote.
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. You pay the same flat daily fee.
How do you handle last-minute call-outs?+
This is what the platform is built for. The moment you post, our system sends targeted notifications to substitutes who match your criteria and are available — including subs who have worked in your building before.
What if we don't need coverage some weeks?+
You only pay for the days substitutes actually work. No upfront cost, no monthly minimum, no charge for a quiet week.
