CBES® credentialing involves a 2-step assessment process that determines the student’s

  1. understanding of knowledge and key principles imparted in the CBES course and,
  2. abilities to competently apply CBES®knowledge and principles in actual office and field ergonomic assessments.

  3. Enroll in Course

CBES Examination


CBES® Examination



The multiple-choice CBES® examination is administered to test the student’s knowledge of the key points addressed in the CBES® course. A passing score of 80% is required. CBES® examination grades are maintained strictly confidential and are not shared with anyone without expressed written permission of the student. Scores below 80% require a re-take examination with a resulting pass score to continue the credentialing process. Re-takes require a $75 administrative fee.

CBES® Ergonomic Assessment

Each student desiring to be credentialed will be asked to complete 5 office and 5 field ergonomic examinations.

Office Ergonomics

The CBES® Office Ergonomic Evaluation form provided during the CBES® course must be used for all office ergonomic assessments for credentialing.

Photographs must accompany the report that clearly show before and after ergonomic interventions. It is understood that some office ergonomic recommendations resulting from your assessment can involve engineering changes that may not be authorized by the employer to incorporate, or that may be too time consuming to incorporate in order to submit your assessment report on time. In such cases photographs of such changes are not required for submission of the assessment.

Field Ergonomics

The CBES® Field Ergonomic Evaluation form provided during the CBES® course must be used for all field ergonomic assessments for credentialing. Field ergonomic reports can be based on a specific job task or job task cycle. Different job tasks or job task cycles from the same work environment can be provided to satisfy the criteria for credentialing.

At least one of the five field ergonomic assessments must show application of the NIOSH lift equation and at least one of the five field ergonomic assessments must show one must show the use of the REBA form. Completed NIOSH Lift Equation and REBA work sheets (provided in the CBES® course) must be submitted along with the field ergonomic reports.

Photographs must accompany the report that clearly show before and after ergonomic interventions. It is understood that some field ergonomic recommendations resulting from your assessment can involve engineering changes that may not be authorized by the employer to incorporate, or that may be too time consuming to incorporate in order to submit your assessment report on time. In such cases photographs of such changes are not required for submission of the assessment.


Deadline for Ergonomic Report Submission

A maximum period of 6 months following the date of the CBES® course completion is allowed for report submissions.

Reviews of Ergonomic Report Submissions

If submitted CBES® ergonomic reports reveal satisfactory competence and understanding of key concepts, reports will be accepted as sufficient for CBES® credentialing and maintained on file with the student’s CBES® examination. If insufficient evidence of full competency is demonstrated, the basis for constructive improvement will be provided in writing to the student. A request for an additional report or reports to address any deficiencies identified will be submitted. Once the additional report or reports are received and competency shown, then the student will be awarded the CBES® credential.

Once credentialed, the student will be registered at ISR Institute as being CBES® credentialed. Credentialed students will receive a professional certificate suitable for framing specifying successful fulfillment of the CBES® course and fieldwork for credentialling. The credentialed student will then be able to legally designate CBES® behind his/her name.
