Cleanroom Certification

The Cleanroom Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests cleanroom knowledge — cleanroom classification and design, gowning and personnel behaviour, cleaning, disinfection and material transfer, and environmental monitoring and qualification — written to ISO 14644-1 and 14644-2, EU GMP Annex 1 (2022) and USP <797> for 2026. Covers pharmaceutical, semiconductor and other controlled environments. Score 70% or more on its 20 questions to earn a verifiable Cleanroom Proficiency certificate (SOA-C8). Every question is based on published standards and research — including EudraLex Volume 4: EU Good Manufacturing Practice guidelines (including Annex 1, 11 and 15) (European Commission), ISO 14644-1:2015 Cleanrooms and associated controlled environments, Part 1: classification of air cleanliness by particle concentration (ISO), USP General Chapter <797> Pharmaceutical Compounding: Sterile Preparations (2023 revision) (United States Pharmacopeia) — 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: EudraLex Volume 4: EU Good Manufacturing Practice guidelines (including Annex 1, 11 and 15) (European Commission); ISO 14644-1:2015 Cleanrooms and associated controlled environments, Part 1: classification of air cleanliness by particle concentration (ISO); USP General Chapter <797> Pharmaceutical Compounding: Sterile Preparations (2023 revision) (United States Pharmacopeia). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Classification and Design (ISO classes and GMP grades, Airflow and filtration and Pressure cascades); Gowning and Behaviour (Gowning, Personnel behaviour and Hygiene); Cleaning, Disinfection and Materials (Cleaning methods, Disinfectants and Material transfer); Monitoring and Qualification (Non-viable monitoring, Viable monitoring and Qualification and deviations). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Cleanroom operator or technician, Aseptic processing operator, Quality assurance or microbiology analyst, Facilities or HVAC technician for cleanrooms and Semiconductor fab technician. It suits anyone who wants a quick, verifiable way to show Cleanroom knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

ISO 14644-1 classifies cleanrooms from ISO Class 1 (cleanest) to ISO Class 9 by the maximum number of airborne particles per cubic metre at specified sizes. Pharmaceutical cleanrooms in the EU also use GMP grades A to D, which add microbiological limits.

People. Operators shed skin particles and microorganisms, so correct gowning, slow and deliberate movement, and good aseptic technique are the most important controls after the facility's design.
