@cyborg5 there are two authorities to consider in relation to formal qualification. When claiming points, you deal with immigration requirements. You can claim 15 points if qualification is equivalent to at least an Australian bachelor degree, related or not related to your occupation. With regards to the relevant assessing authority, a separate requirement has to meet to get a positive outcome.
I must say, you need to do further reading on both skills assessment and Visa application process. Don’t get confused with requirements between skills assessment vs immigration rules. All the best.
