@kwonshinhee Just sharing my experience -- non ICT grad ako then applied for ACS skills assessment for ICT security specialist.
I submitted RPL, then ACS claimed 6 years of my work experience (10 years total ko). so less than 4 years lang naclaim ko na points which is 5 pts minimum. My ACS result did not mention anything kung ano equivalent or comparable ng degree ko. Per my research, pag non ICT grad ka talaga, minimum 6 years experience kukunin ni ACS sa RPL mo so yun matitira lang pwede mo claim points. So I don't think you need to go to VETASSESS if you are non ICT graduate, i've read some questions on other threads about this.
