Maintenance Technician Certification

The Maintenance Technician Certification is a free beginner-level, 15-minute skill test from Science of Apps. It tests the multi-skill knowledge a building or facilities maintenance technician needs — electrical basics and safe work practices, plumbing, HVAC and refrigeration, and carpentry, building systems and preventive maintenance — written to OSHA lockout/tagout, ladder and hazard communication rules, NFPA 70 and 70E, the Uniform Plumbing Code, EPA Section 608 and ASHRAE guidance for 2026. For industrial machinery maintenance, see the separate industrial maintenance test. Score 70% or more on its 15 questions to earn a verifiable Maintenance Technician Proficiency certificate (SOA-MT2). Every question is based on published standards and research — including IFMA credentials: Facility Management Professional (FMP) and core competencies (International Facility Management Association), NFPA 70: National Electrical Code (NEC) (National Fire Protection Association), Uniform Plumbing Code (IAPMO) — and each answer is explained with its source.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: IFMA credentials: Facility Management Professional (FMP) and core competencies (International Facility Management Association); NFPA 70: National Electrical Code (NEC) (National Fire Protection Association); Uniform Plumbing Code (IAPMO); ASHRAE standards and guidelines (ASHRAE); NFPA 70E: Electrical safety in the workplace (NFPA); Section 608 refrigerant management (US EPA). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Three skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Electrical Basics and Safety (Circuits and Ohm's law, Lockout/tagout and PPE and Outlets, breakers and GFCIs); Plumbing, HVAC and Refrigeration (Plumbing repairs, Heating and cooling and Refrigerant rules); Carpentry, Building Systems and Preventive Maintenance (Repairs and finishes, Fire and life safety and Preventive maintenance planning). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Building or facilities maintenance technician, Apartment or property maintenance technician, School, hospital or hotel maintenance staff, Handyperson or general maintenance worker and Maintenance supervisor. It suits anyone who wants a quick, verifiable way to show Maintenance Technician knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

Building maintenance certifications, such as the US Certificate for Apartment Maintenance Technicians or facilities technician programmes, cover electrical, plumbing, HVAC, appliance and carpentry repairs, plus safety and preventive maintenance. Many employers also require EPA Section 608 certification to handle refrigerants.

In the US, anyone who maintains, services or repairs equipment that could release refrigerants, such as air conditioners and refrigerators, must hold EPA Section 608 certification. Other countries have similar refrigerant handling licences.
