ISA Certified Arborist Prepatory Programme (Singapore) and ISA Certified Arborist Application (US and Other Countries)

About 8 years ago, it was acceptable to have a diploma in arboriculture or equivalent, plus 2 years of relavent experience in order to be accepted into the ISA Certified Arborist Prepartory Programme (see Table 1). This is programme is a series of classes facilitated by the National Parks Board in Singapore, which a candidate could go through before taking the exams to become an ISA Certified Arborist. Taking the classes could increase the chances that the candidate would pass the exams. Fast forward 5 years, around year 2017, the prerequisite changed to that of a two-year degree in arboriculture plus two years of practical experience. How many people in Singapore would have such a degree and even if one had the inclination to attain it, one would have to obtain it overseas. As for the four-year degree "in a related field" - what would constitute as related?

In the US and other countries, their statutory boards does not organise prepartory programmes for potential ISA certified Arborists, but rather the country Chapters, associate organisations or interest groups. ISA just administer the applications, exams and certification. It has stated the eligibility of candidates who wish to apply for the exam (see Table 2). Almost the same as the Singapore requirements, ISA require degree holders to have either a two-year associate degree with 2 years practical experience or four-year bachelor degree with 1 year practical experience. But what is lacking in the Singapore requirements is the "Assessment-Based Certificate Programs (Diplomas, Certificates)" category. "900 hours of assessed training" could be roughly 1 year of full-time study/training, and 1800 hours of assessed training could be roughly 2 years of full-time study/training.

Is the ISA Certified Arborist Prepartory Programme in Singapore leaving out candidates who do not have two-year or four-year degrees?
