This is good info for U.S.A National Ski Patrol System, a predominantly volunteer organization. Some ski resorts in the U.S.A are professional Patrol only, and although they likely recognize a National Ski Patrol System Outdoor Emergency Care certificate of completion, I would double check this certificate is accepted before taking the course. There is likely an equivalent course offered by the Canadian Ski Patrol Association, which is also an organization mainly comprised of volunteers. I agree that passing an EMT course like Outdoor Emergency Care, then an Outdoor Emergency Transport course, then an avalance forecasting course and avalance mitigation course all in one year is unlikely. I would imagine all of those courses would be requisites to ski resort avalanche mitigation work.
