A complete school custodian training program covers thirteen things: legally required safety training, asbestos awareness, bloodborne pathogen response, proper cleaning techniques, hygiene and infection control, cleaning schedules, high-touch surfaces, emergency procedures, energy awareness, customer service, certification and ongoing training, performance evaluations, and teamwork built on open communication. Some of those are federal requirements with deadlines attached. The rest are the difference between a custodial team that cleans and one that protects the learning environment.
That distinction matters more than most training conversations admit. Schools are dense, high-contact buildings where illness moves fast, and the CDC reports that hand hygiene programs alone reduce gastrointestinal absenteeism in schoolchildren by 29 to 57%. Your custodians are the adults who make that math work. Here is how to train them like it.
The Training Timeline Every School Facility Manager Should Know
Before the tips, the deadlines. Three pieces of custodian training are not optional in the United States, and two have clocks attached:
| Training | Who needs it | When | Requirement |
|---|---|---|---|
| Asbestos awareness (2 hours) | All custodial and maintenance staff in school buildings with asbestos-containing materials | Within 60 days of hire | AHERA (EPA) |
| Bloodborne pathogens | Anyone expected to clean up blood or bodily fluids, which in a school means custodians | Before exposure-risk tasks, then annually | OSHA 29 CFR 1910.1030 |
| Hazard communication | Anyone who works with cleaning chemicals | Before first assignment, and when new hazards are introduced | OSHA 29 CFR 1910.1200 |
If your program covers those three on schedule, everything else on this list makes your team better. If it doesn’t, start there.
The 13 Custodian Training Tips
Emphasize Safety From Day One
Safety training is first because some of it is federally required and all of it protects your people. Cover chemical handling and storage, personal protective equipment, ladder safety, lifting technique, wet-floor and slip-fall procedures, and how to identify and report hazards. Then go beyond the generic list: schools have specifics. Custodians should know which closets hold what chemicals, where safety data sheets live, and what the school’s incident-reporting chain looks like. Document every session, because OSHA training requirements come with recordkeeping expectations, and an undocumented training might as well not have happened.
Cover Asbestos Awareness Within 60 Days
This is the school-specific requirement that generic custodian training guides skip. Under AHERA, custodial and maintenance staff working in school buildings that contain asbestos-containing materials must receive two hours of asbestos awareness training, and new hires must get it within 60 days of starting work. Staff whose duties involve disturbing asbestos-containing material need an additional 14 hours. Awareness training teaches custodians what not to touch: where the school’s asbestos management plan is kept, which materials in their building contain asbestos, and why a damaged floor tile gets reported instead of sanded. Most school buildings built before the 1980s contain some asbestos-containing material, so treat this as standard onboarding, not an edge case.
Train Bloodborne Pathogen Response Like It Will Happen
In a school, it will: nosebleeds, playground injuries, vomit in a hallway. OSHA’s bloodborne pathogens standard requires annual training for employees expected to handle blood or other potentially infectious materials, and it obligates the employer to maintain an exposure control plan and offer hepatitis B vaccination to at-risk staff. Training should be concrete: glove and eye protection procedure, the specific disinfectant your school stocks for biohazard cleanup, bagging and disposal steps, and what to do immediately after an accidental exposure. A custodian who has rehearsed this cleans up an incident calmly in minutes. One who hasn’t improvises, and improvisation is how exposures happen.
Teach Proper Cleaning Techniques, Not Just Task Lists
“Clean the restrooms” is an assignment, not a technique. Train the method: high-to-low dusting, microfiber use, color-coded cloths so a restroom rag never touches a cafeteria table, correct dilution ratios, and the one habit that separates trained teams from untrained ones, disinfectant contact time. Every disinfectant label states how long a surface must stay wet to actually kill what it claims to kill. A product sprayed and immediately wiped is theater. Build contact times into the procedure for each area, and teach why they exist, because custodians follow rules they understand far more consistently than rules they don’t.
Make Hygiene and Infection Control a Core Competency
Schools concentrate germs, and custodial work is the school’s infection control program in practice. Train the transmission basics: which illnesses move through schools, how they travel on surfaces, and why some germs need specific products. Norovirus, the classic school outbreak virus, survives on surfaces for up to two weeks and shrugs off many standard disinfectants; the EPA maintains organism-specific disinfectant lists that name the products that work. Our guide to the illnesses and diseases caused by uncleanliness is a useful training companion here. And keep preaching handwashing, for staff and students alike, because the CDC’s numbers on absenteeism reduction make it the cheapest infection control tool a school has.
Establish and Explain the Cleaning Schedule
Create a schedule that covers daily, weekly, monthly, and seasonal tasks, including the summer deep clean that resets the building each year, and train custodians to work it. Explain the reasoning behind frequencies: why restrooms get multiple daily passes while storage areas get weekly attention. A schedule people understand survives busy weeks; a schedule handed down without explanation quietly erodes. Digital cleaning checklists help here, turning the schedule into daily task lists that update when the program changes, so training and reality never drift apart.
Focus on High-Touch Surfaces
Doorknobs, light switches, handrails, water fountains, shared keyboards, desks, and restroom fixtures carry most of a school’s germ traffic. Train custodians to treat these as a distinct daily discipline with the right product and contact time, not an afterthought at the end of a route. During cold, flu, and norovirus season, the high-touch circuit is the first thing to increase in frequency, so make sure the team knows both the standard cadence and the outbreak cadence before either is needed.
Cover Emergency Procedures
Spills, floods, equipment failures, fire alarms, lockdowns, weather events: custodians are often the first responders to a building problem and are on site during events when other adults are managing students. Train the response procedures for each scenario, the reporting chain, and where shutoffs and emergency supplies are located. Walk the building during training rather than describing it in a classroom. A custodian who knows exactly where the water shutoff is saves a gym floor.
Teach Energy and Resource Awareness
Custodians touch every room in the building after hours, which makes them the school’s best energy patrol. Train them to power down what should be off, report leaks and malfunctioning fixtures promptly, and use chemicals at correct dilutions, which is both a safety practice and a budget one. Utility and supply savings land in the same school budget that funds their department, and framing it that way turns a chore into advocacy.
Provide Customer Service Training
Custodians interact with students, teachers, parents, and visitors daily, and in a school they are also role models whether anyone planned it or not. Train professional, courteous interaction: how to respond to a teacher’s request, how to handle an interruption mid-task, when to redirect a request to a supervisor. Teams that handle these moments well build the kind of goodwill that shows up later as budget support and job security. It also shows up in enrollment optics; we’ve written before about how facility cleanliness shapes campus impressions.
Offer Certification and Ongoing Training
Cleaning science, products, and equipment keep evolving, and the industry’s own institutions do serious training work. ISSA’s Cleaning Management Institute offers a Certified Custodial Technician program covering disinfection, floor care, carpet, and restroom work, with certification good for two years. ISSA also publishes the Clean Standard: K-12, built on a “clean, measure, monitor” approach to school cleaning quality, and APPA maintains the custodial operations guidelines that education facility departments benchmark against. Sending custodians through recognized programs improves the work and tells your team the district considers them professionals worth investing in.
Conduct Regular Performance Evaluations
Evaluate against the standards you trained, at a predictable cadence, with specifics. Inspection results make evaluations objective instead of impressionistic: when quality checks are documented in cleaning inspection software, a supervisor can show a custodian exactly which areas pass consistently and which need work, and the conversation becomes coaching rather than opinion. Use evaluations to spot retraining needs early, recognize strengths publicly, and identify who is ready for lead roles.
Build Teamwork, Pride, and Open Communication
School custodial work splits across day and night shifts that rarely meet, which makes handoffs the weak point of most programs. Train the team to communicate across that gap: what got done, what didn’t, what needs attention tomorrow. Shift notes scribbled on paper get lost; a shared system where day staff flag issues and night staff close them keeps the building consistent. The JM Connect mobile app exists for exactly this, connecting custodians in the field to supervisors and to each other so the second shift starts informed instead of guessing.
Communication is also how pride takes root. The custodians who stay, improve, and care are the ones who feel their work matters and their voice is heard. Recognize good work visibly, celebrate milestones, and build real channels for custodians to raise concerns and suggest improvements, because nobody knows the building’s problems earlier than the people who clean it nightly. Then act on what they tell you. A facility manager who implements a custodian’s suggestion and credits them has done more for retention than any pizza party.

What This Looks Like in Practice
A workable onboarding sequence for a new school custodian: safety fundamentals and hazard communication before the first solo shift, bloodborne pathogen training before any exposure-risk duties, asbestos awareness inside the 60-day window, cleaning technique and schedule training through the first month alongside an experienced teammate, and a 90-day evaluation that sets the baseline for ongoing coaching. Annual refreshers for bloodborne pathogens and a standing calendar for certification and skills training carry it forward from there.
Tracking all of that per employee is its own job, which is why school custodial teams increasingly run training records, checklists, and inspections in one system; our companion piece on what school custodial teams should track inside their management software goes deeper on that.
Frequently Asked Questions
What custodian training is legally required for schools?
Three things stand out in the United States: two hours of asbestos awareness training under AHERA for custodial and maintenance staff in school buildings with asbestos-containing materials (within 60 days of hire), annual OSHA bloodborne pathogens training for staff expected to clean up blood or bodily fluids, and OSHA hazard communication training before working with cleaning chemicals. State requirements can add to this list, so check yours.
How long should custodian training take?
Compliance basics fit into the first weeks, but competence takes longer: plan on roughly 30 days of structured onboarding with an experienced teammate before a new custodian runs a full route independently, then a 90-day evaluation. Training after that is ongoing, not finished.
What certifications exist for custodial staff?
ISSA’s Cleaning Management Institute offers Custodial Technician certification at basic and advanced levels, and CIMS certification exists at the organizational level for cleaning operations. For schools specifically, the ISSA Clean Standard: K-12 provides a framework for measuring cleaning effectiveness rather than certifying individuals.
Do contracted cleaning companies need the same training in schools?
Yes. AHERA’s custodial training requirements and OSHA’s standards apply to the people doing the work in the building, whether the district employs them or a building service contractor does. Districts hiring a BSC should ask for training documentation during procurement, and contractors who can produce it immediately hold a real competitive advantage in education bids.
A Well-Trained Custodial Team Is a Health Asset
The thirteen tips above split into two halves that reinforce each other: the compliance half that keeps your district legal and your people safe, and the craft half that turns cleaning into measurable building health. Facility managers who train both halves, document the training, and reinforce it through daily tools end up with custodial teams that need less supervision, not more.
