The best place to start is by choosing where you’d like to work. If your answer is everywhere, then a certification like CASI is a great idea.
CASI snowboard instructor certification is accepted in many different countries worldwide and its courses are delivered in six different countries, at the time of writing this article.
After choosing where you’d like to work, the next step is to check your certification with the governing body of that country. For example, if you want to work in Canada, check with CASI to see if your certification is valid. If not, find out how to make it valid, or look into taking a CASI snowboard instructor course.
If you plan on taking snowboard instructor courses in the country where you are working, in many cases the governing body will grant you one level of certification lower than what you hold.
For example, if you arrive in Canada with a NZSIA Level 3, then you might be asked to take the CASI Level 3 course as a starting point in that system. You can probably still teach at your local resort with your NZSIA Level 3, but will need to test for CASI Level 3 when taking certification courses in the new system.
