I highly recommend the MPI Level 2a course. I work with architects and designers on new construction projects as well as remodel and renovation work, and I signed up because I wanted the accreditation as well as the insight to better serve my customers. The course covered some material I was unfamiliar with and was a great refresher as well; the sections on concrete and metal were particularly valuable. This is a very comprehensive and detailed course covering a wide variety of substrates in various degrees of lifespan and conditions, which is the real world. Now that I’m an MPI-Certified Architectural Coating Specialist, I’ve set myself apart from the competition in my ability to identify substrate conditions, answer customer questions, recommend appropriate coating systems, and offer expert advice that will prevent jobsite problems down the road.
