Certified Industrial Hygienist (CIH) Certification Course Details: Fees, Duration, Eligibility, Course Content, How To Apply


Becoming a Certified Industrial Hygienist (CIH) is a significant step in the career of those dedicated to ensuring safe and healthy working environments. The CIH certification is recognized globally and is a testament to an individual’s expertise in industrial hygiene. In this article, we will delve into the details of the CIH certification, covering its fees, duration, eligibility criteria, course content, and how to apply.


The cost of obtaining the CIH certification can vary depending on several factors, including your membership status with the American Board of Industrial Hygiene (ABIH). As of my last knowledge update in September 2021, here is a general breakdown of the fees:

  1. Application Fee: The initial application fee typically ranged from $125 to $350. This fee covers the review of your eligibility and qualifications.
  2. Examination Fee: The CIH exam fee ranged from $350 to $700, depending on your ABIH membership status. ABIH members usually pay a reduced fee.
  3. Annual Maintenance Fee: After obtaining the CIH certification, you are required to pay an annual maintenance fee to keep your certification active. This fee usually falls in the range of $130 to $240.

Please note that these fees may have changed since my last update. It’s essential to visit the ABIH website or contact them directly for the most up-to-date fee information.


The duration of the CIH certification process can vary from one individual to another. Here is a rough timeline:

  1. Application Review: Once you submit your application, the ABIH will review it for eligibility. This process can take several weeks.
  2. Exam Preparation: Preparing for the CIH exam is a crucial step. The duration of your preparation will depend on your prior knowledge and experience. Many candidates spend several months studying for the exam.
  3. Examination: The CIH exam is typically held twice a year. It consists of two parts: a computer-based multiple-choice section and a written essay section. The entire examination process takes one day.
  4. Results: You’ll receive your exam results within a few weeks of taking the test.
  5. Certification: If you pass the CIH exam and meet all other requirements, you’ll be awarded the CIH certification.


To be eligible for the CIH certification, you must meet specific educational and experience requirements. As of my last update in September 2021, the general eligibility criteria include:

  • A bachelor’s degree in a related field (e.g., industrial hygiene, environmental health, or a related science).

Please note that these requirements may have evolved. Always check the ABIH website for the most current eligibility criteria.
