Does anyone know the codes for EPA Type 1,2,3 and Universal for promotion points under certifications?

Are you referring to turning those certs into Promotion Points? See this link...then also seek out your Education Office for further clarification. I've searched the COOL website, but I can't find anything specific about actual points worth.

There is an old post on here that I also found where it stated, "DOD/EPA 608 Refrigerant Processing Certification is worth promotion points for Soldiers who hold the MOS of 91C." But that was also a post from 9 years ago
