Calculating CM Credit

CM credit is claimed in at least one of the CM Areas of IH, IH Ethics or Safety (definitions below) at a rate of 0.167 point per technical contact hour. The event must be at least one hour except for ethics which can be any length.

Technical Contact time includes technical portions such as presentations, lectures, break outs, Q&A, exams, event overview, event recaps, and discussions. The non-technical portions of an event should not be counted, e.g., generic welcome speeches, participant introductions, breaks, meals, networking, exhibitor time, roundtables or discussions with unspecified topics, social tours.

Note: Newer CM worksheets will accept either CM points or CM contact hours. Older worksheets only use CM points and hours must be converted at a rate of 0.167 point per hour.

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.

The Diplomate should claim their technical contact hours as reported by the course Sponsor, regardless of the actual time it takes to complete the course. For example, a 3 hour class completed in 4 hours should be claimed for "3 hours" on the CM Worksheet.

The same course may be claimed only one time per CM cycle. An initial training course and then later, a refresher training course are counted as two different courses.

Note: A course can be repeated and then claimed in different CM cycles.

Academic Courses Academic courses related to IH, Safety or Ethics receive 15 hours of CM credit per academic semester credit hour. (10 hours of CM credit if on the quarter-hour system). IH Ethics CM credit is capped at 30 hours per CM cycle.
Conferences The Diplomate should claim their technical contact hours based on their actual participation in the technical sessions. This is often less than the maximum possible time as reported by the Sponsor.
Training Inside Your Organization
Training inside your company or business can be claimed for CM credit if it meets the time and subject matter specifications for CM Credit.

Note: Many topics do not qualify since they are already credited in Category 1 Active Practice, e.g., leadership messages, goal reviews, strategy sessions, problem solving sessions, area updates.
Doctoral & Masters 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 meets the criteria for subject matter and length.
Event Delivery Methods Physical presence events and distance learning events (e.g. virtual courses, home study) are treated the same for purposes of CM credit calculations.
Management Training

CM credit for general management* training was discontinued in 2009. However, if the Management training has significant EH&S aspects in the content, it can be currently claimed in the IH CM Area.

*General management training generically addresses professional development of management and leadership skills, 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.

CM Areas

Industrial Hygiene Events are considered to be the IH CM Area if the subject matter aligns with the IH Rubrics or is identified on the IH Job Analysis. Additional areas will be accepted if there is a human health aspect.
Safety Events are considered to be the Safety CM Area if the subject matter is more acute hazard oriented and not addressed by the IH definition. 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.
IH Ethics Events are considered to be the IH Ethics CM Area if the subject matter aligns with the ABIH Code of Ethics or the AIH, AIHA, ACGIH Member Ethical Principles.

ABIH is interpreting this very broadly today. For example, appropriate subject matter includes: business conflicts, workplace relationships, technical judgment that compromises the values of an organization, integrity, professional conduct, confidentiality of sensitive information (e.g. HIPPA, human subject protection during research projects, employee medical records), conflict of interest, and intellectual property rights/plagiarism.

Some additional guidance is available in the Ethics FAQ.

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.

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

Acceptable records include but are not limited to:

CM Credit Calculations If the Diplomate has calculated their CM credit, retain an agenda, schedule or other document showing topics and contact time.

A certificate of completion may be adequate if it clearly shows the contact time and subject matter that aligns to at least one of the CM Areas.
Attendance Records
  • Certificate of Completion, attendance roster, acknowledgement letter, on-site registration receipt for same day event, transcript showing event completion or Attendance Verification Form, or
  • Registration record and evidence of physical presence in the city on the day(s) of the event, e.g. approved expense report, hotel, meal or parking receipts
    • An AIHA Education Transcript for a Conference is a registration receipt; it by itself is not a complete participation record
    • Airline boarding passes show evidence for the days of travel; these may not be sufficient for a multi-day conference
  • CIH Vouching: For one event during a CM cycle, a Diplomate is allowed to have another Diplomate vouch for attendance. This is expected to be used only when other proof-of-participation is not available.
Unacceptable Records
  • Advance travel purchases - these show intent, not participation
  • Event Agenda/Conference Schedule – can be obtained without actually participating
  • ABIH CM Event Letter of Approval (for CM points) – does not show proof of participation
  • Event badges – often, these are distributed prior to the event
  • Documentation dated differently than the dates claimed on the worksheet
