The Test Committee recently met and reviewed the passing score, as set in the previous format of domains, and considered the passing score for the exam. Based upon the Angoff Technique, widely used in many certification programs in North America, the Test Committee determined to set the passing score at 2% points higher than the 70% set more than 15 years ago. In addition to the Angoff technique, the Test Committee, made up of a diverse group of professionals from all segments of the arborist community, justified the slight incremental change in the passing score as consistent with the increase in training and educational materials now available as well the increased expectations of employers of Certified Arborists.
The change in exam format and the application of the new passing score will be July 1, 2009.You will be required to obtain a 72% overall score on the exam in order to have a passing score. If a passing score of 72% is not achieved you will have to retake the entire exam until a passing score is obtained to gain certification.
Unfortunately, when changes like this occur, there is always a group caught in transition. You must complete your exam under the existing requirements and you will have until September 30, 2009 to do so. The ISA Certification team understands your challenges and will work with you in every way possible to help you complete your domain retakes before that date.
