The CTCB-I Course is a well developed and established course provided internationally through contamination control associations like the Contamination Control Network.
There are two levels of training and exam called Professional and Associate. There is theory training for all prior to exams and practical tests. The Professional has to do a two hour theory exam, a half hour Particle Counting written test, then two half hour practical exams on airflow and filter integrity testing with report writing sessions afterwards - they are marked on each of those and have to pass all elements to the required standard to achieve Professional certification. The Associates only take the two hour theory exam.
