Construction Health and Safety Technician (CHST)


The Board of Certified Safety Professionals (BCSP) is an independent, not for profit certifying agency that was founded based on recommendations from an American Society of Safety Engineers (ASSE) study of the skills, experience and job roles of health and safety professionals. The initial certification board was formed and by 1969, certification standards were developed and the board became an independent, nonprofit entity. Participation of a variety of sponsoring organizations assures that the diverse interests of industries that employ health and safety professionals are represented in standards-setting and certification testing processes.[1] Construction safety is a growing field. Since it was first recognized as a unique professional specialty, its ranks have grown to the point where it is the largest practice specialty within the membership organization of the American Society of Safety Engineers.[2] The CHST certification exam was first given in 1992 to recognize the importance of specialized experience and skills in the field.[3] As of 2012, there were 2600 actively certified CHSTs.[4]

CHST Study Guide

The CHST exam is used to assess the knowledge and skills needed by construction industry personnel who work in a health and safety capacity to prevent illness and injury on the job site. Certified individuals may work for general contractors, subcontractors, inspectors, or construction safety consultants. [5] The CHST can increase an individual’s earning potential. According to the latest salary survey data, CHST salaries average over $83,000 per year.[6] To be eligible for the CHST exam, candidates must possess a high school diploma or GED, along with 3 or more years’ work experience in the construction industry in which health, safety and/or environmental work constituted a minimum of 35% of the candidate’s job.[7]

Test Administration

CHST Flashcards

The cost to take the CHST exam is $440, which includes a non-refundable $140 application processing fee.[8] Fee waivers are available for US military veterans, federal government employees, and faculty of accredited colleges and universities who teach at least one health and safety course.[9] Candidates schedule their exam date directly with any of hundreds of Pearson VUE testing centers across the United States and Canada. Exams are available during normal business days throughout the year.[10] Eligible candidates must schedule their exam before their eligibility end date given to them by BCSP. If they wish to take their exam after the end of their eligibility period, they must reapply with the full testing fee. This can be avoided by applying for a one-year extension 60 or more days prior to the eligibility end date provided in the examination authorization letter.[11] Candidates who do not pass the exam receive a score report showing the subject matter areas in which they need improvement. BSCP recommends that candidates focus their remedial study on those areas of weakness before applying to retake the exam.[12]

The total score is calculated by adding the number of correctly answered items. Incorrect answers are not counted and therefore it is advantageous to answer all items on the exam, even if some are educated guesses. The minimum passing score for each revision of the OHST exam is determined by evaluating each test item and assigning a score value based on the item’s difficulty. Values are added and the minimum score value required to demonstrate competence is established.[15]
