Calculating CM Credit

CM credit can be claimed for an educational event completed during the CM cycle that is targeted to the professional level (not technician), advancing the person's technical knowledge and skills in the areas of IH, safety, or ethics. 

IH or safety training must be at least one hour; ethics training can be any length.

CM credit is claimed at a rate of 0.167 points per technical contact hour in the CM Areas of IH, Ethics, Management, or Safety.

A technical contact hour is the time spent in technical sessions. It includes technical presentations, lectures, breakouts, Q&A, exams, event overview, event recaps, and discussions. It does not include the non-technical activities, e.g., meals, breaks, exhibitor time, networking, participant introductions, social tours, generic welcome speeches.


  • Claim the hours as provided by the Course Sponsor. Note that some course providers use CEUs, where 1 CEU = 10 technical contact hours. If the hours were not provided by the Sponsor, calculate the hours from an agenda or schedule. One (1) hour of technical contact time = 0.167 points.
  • For Academic Courses, claim 15 contact hours (2.5 CM points) for each academic semester credit hour. If on the quarter-hour system, claim 10 contact hours (1.67 CM point) for each academic quarter-hour credit.


  • Claim 3 hours for each half-day of attendance, or
  • Track and claim your actual hours of attendance in the technical sessions.

Note: Claiming the maximum time for a conference often means that you attended every possible technical session and you did not do any non-technical activity, e.g., breaks, networking, Vendors visits, awards, social events, etc.

As a matter of convenience, most Diplomates use the "3 hours/half day" estimate. As with courses, one (1) hour of technical contact time = 0.167 points.

For additional information, see Calculating CM Credit For Educational Events

CM Approval Numbers CM approval numbers are not required on the CM worksheets for any event, past or future.

A course may be claimed only one time per CM cycle because typically, the technical content does not change significantly (>50%) each time it's taught. If the content does change by >50%, each attendance can be claimed. The Diplomate will want to retain records to verify that the content has changed.

A course can be repeated and claimed in a later CM cycle.

For CM purposes, an initial training course and then later, a refresher training course are counted as two different courses.

Per Board legacy rule, First-Aid, CPR and AED classes are not eligible for CM credit. 

Conferences Conferences can be claimed for each attendance because it is assumed that the technical content changes for each conference.
Training Inside Your Organization

Training inside your company can be claimed for CM credit if it meets the subject matter and time specifications listed above.

Note: Many internal company training topics do not qualify for CM credit in Category 4 because the Diplomate already receives CM credit in Category 1 Active Practice, e.g., leadership messages, goal reviews, strategy sessions, problem-solving sessions, area updates.

These must be designated activities with proof of participation meeting the same records requirements as other items in Category 4 (date, time, length, subject, or title clearly defined, proof of attendance, signature of person in responsible charge, etc.)

Graduate Degrees

Doctoral: 10 IH points (60 hours) can be claimed for a Doctoral degree completed during the CM cycle in IH or an IH-related field.

Masters: CM credit is not awarded for a Masters thesis (or degree).

Graduate Courses: Academic courses in the Doctoral or Masters programs can be claimed for CM credit if the course is IH, safety, management, or ethics related.
Distance Learning Distance learning events (e.g. virtual seminars/courses/conferenes, home study, etc) and physical presence events are treated the same for purposes of CM credit calculations.

CM Areas

Ethics The subject matter aligns with the BGC® Code of Ethics or the AIH, AIHA, ACGIH Member Ethical Principles. This type of subject matter concerns topics such as fairness, honesty, truthfulness, integrity, accuracy, objectivity, confidentiality, compliance, legality, conflicts of interest, conflict management, undue influence, equal opportunity, diversity, intellectual property rights/plagiarism, use of certification marks and professional competency/limitations (i.e., when to refer a client).

Additional guidance is available in the Ethics FAQ.
Industrial Hygiene The subject matter aligns with the IH Rubrics or is identified on the CIH Exam Blueprint. Additional areas will be considered if there is a human health aspect to the content.
Management - General

General management training, including Leadership, addresses skill development which is generically applicable to many professionals, not just IH professionals, e.g., communication techniques, technical writing, presentation techniques, organizational effectiveness, media training, computer skills, supervisory skills, quality training, financial or accounting training, expert witness training, project management.

(If the general management training has significant EH&S aspects in the content, it can still be claimed in the Industrial Hygiene area of Category 4.)

Safety The subject matter is more acute hazard oriented and not included in the IH CM Area. For example, Safety CM credit can be claimed for guarding, electrical hazards, fall protection, workplace violence, or physical security. Note: Confined Space Entry is considered to be the IH CM area. Per Board legacy rule, First-Aid, CPR and AED classes are not eligible for CM credit.
Additional Resources Additional examples for each of the CM Areas can be found in the "Overview" and the "Supplemental Information" documents, which are used to easily explain the CM program. Both can be found in the ABIH Document Library or accessed through the Calculating CM Credit For Educational Events web page.

Diplomate records must be consistent with the dates and activities listed on the CM worksheet. If participation cannot be verified, the Diplomate should not list the item on the worksheet.

An acceptable proof-of-completion record is one that shows the Diplomate’s name, date of completion, event title, event Sponsor/Provider, and the duration (e.g. hours or CEUs).  If any of this information is missing or if the subject matter is not clear from the event title, then additional records will be needed, e.g., event description, agenda, or schedule.


  • Class or Course: When you attend a class or course, you only need one acceptable proof-of-completion record such as a certificate, transcript, roster, or other acknowledgment or your participation. (NOTE - If you are claiming the same class more than once during a CM cycle (e.g. annual ethics training), you will also need to retain something which shows that the content changed by more than 50% each time it was taught.)
  • Conference: When you attend a conference, you typically will need two records: 1) a registration receipt and 2) a record such as an expense report which proves that you were physically in the city on the days of the claimed CM credit.

Diplomates should retain records until after a recertification decision has been made.

Acceptable Records:

If the event Sponsor or Provider does generate a participation record, then any one of the following will be acceptable:

  • Certificate, letter/email, transcript, roster, or other Sponsor-generated record showing completion
  • Registration receipt if purchased on-site, at a single-day event
  • Event badge only if issued on-site, at a single-day event

If the event Sponsor or Provider does not generate a participation record and the Sponsor, Provider or Content Owner does not have any additional restrictions for use, participation, or viewing, then the Diplomate may use one of the following:

  • Registration record and evidence of physical presence in the city on the day(s) of the event, e.g. approved expense report, purchase receipts
  • Attendance Roster
  • BGC Attendance Verification Form
  • CIH vouching (allowed once per CM cycle)

NOTE: the AIHA Educational Transcript is a complete record for any AIHA PDC, Webinar, Road Course, or Virtual Conference if it shows "Passed/Attended". However, it is only a registration receipt for any physically-attended AIHA conference. This means that an additional record will be needed to verify physical presence in the event city.  Also, the transcript cannot be used for any non-AIHA event.

Unacceptable Records: The following records typically are not accepted:

  • Advance travel purchases
  • Agenda, Program, Conference Schedules or presentation slides
  • ABIH Letter of Award for CM Points
  • Event badges if distributed prior to the event
  • Airline boarding passes are acceptable for the days of travel but are not sufficient for a multi-day conference
